The Secret to Enterprise Projects: Don’t Care Who Gets the Credit

on Wednesday, 25 February 2015. Posted in General - Misc. Tips, Blog

The Secret to Enterprise Projects: Don’t Care Who Gets the Credit

For a lot of people, having to work alongside others to complete any given project is their least favorite part of the job. Teamwork can be difficult, especially if all members involved have very different personalities that sometimes clash. In fact, 97% of employees and executive surveyed believe that lack of alignment within a team directly impacts the outcome of a project (source).

But usually one of the biggest sources of content when working on a project comes from members becoming more interested in proving their worth by getting credit for their own work, rather than wanting credit for team completion of a project. And really, the truth is that when you stop caring and who gets the credit, you’ll find that working on a project gets much less stressful. Though it might seem counterintuitive, forgetting about who gets the credit for a project will only benefit you as a leader in the long run. Here are 5 reasons why:

Your teammates will enjoy working with you

No one enjoys working with someone who is power hungry or someone who micromanages. Unfortunately for many, teamwork is a necessary evil that dominates the white-collar professional world. According to a recent survey by BusinessWeek, 82% of those surveyed said they depended on partnering with others throughout the day to get their work done. By being the type of team member who is more concerned about the group as a whole, they’ll know that you give them enough room to breathe and develop. Since they don’t feel smothered, it will be much easier for them to follow your advice and requests during the course of a project.

Team efficiency will be boosted

When it comes to team projects, time management is key. And the stress of deadlines is amplified even more when team members don’t agree, can’t get along, or just simply don’t work well together. By focusing on the greater good and helping the cohesion of your group, you’ll find that time coordination will be amplified and your team will finish more work in a given time frame.

Team moral will soar

When people like who they’re working with, team projects can really be an enjoyable experience. On the other hand, team projects can be extremely disappointing if there isn’t cohesion within a group. When surveyed, 86% of employees and executives sited lack of collaboration or ineffective communication for workplace failures (source). Making an effort to be more of a team player and less concerned about individual will help you boost team moral. All members involved will be energized and ready to face any obstacles, ultimately resulting in a positive experience and a successful project outcome.

Their skills will develop more

Because your team members know that they can shine with their individual skills, they’ll do their best in developing them. They won’t stifle their creativity or productivity due to reservations they have about potential reactions from their team.

They’ll stick more to your team

In the business world, a team that works well together on project is as good as gold. Being the type of team member people like to work with means that you’ll have team members who last longer and actually want to stick around to work with you. In the end, you’ll have even more success as a group as you continue to develop the synergy you helped start in the first place.

As Henry Ford stated, “Coming together is a beginning, staying together is progress, and working together is success.” And this entire process is dependent on that team sharing a common goal, using their individual talents to work toward that goal, and using those talents and skills in unison. Worrying less about who is getting the credit and more about the success of the entire group is the first step to achieving that.

Get rid of the lengthy COTS Feasibility Study, Interesting facts & data to make you think twice

Get rid of the lengthy COTS Feasibility Study, Interesting facts & data to make you think twice

 

 

 

 

                                                       Feasibility studies permit planners to outline their ideas on paper before implementing them. This can reveal errors in project design before their implementation negatively affects the project. Applying the lessons gained from a feasibility study can significantly lower the project risks. In my view feasibility studies should never be longer than 4 months, no matter how big your project is let me explain:

The Feasibility study is not a sales pitch, way too often we focus on the COTS (Commercial off the shelf ) product, In my view, this is a fundamental mistake all these products work and are already integrated (PeopleSoft, Oracle EBS, Fusion,JDE, SAP, Siebel) it does not make sense any longer with the vast information out they’re to be completing Feasibility studies with full system analysis like Oracle or SAP that last longer than 4 months.

Why? I have yet to hear in my career that Oracle or SAP cannot perform a certain business function if not vanilla or with a RICE(Report-Interface-Conversion-Extension). Especially know that everyone has adopted a SOA more Open based Architecture.

Below is an email I received by an individual that gave me approval to print this email onto this article, he shares his experience about their feasibility study:

Subject: RE: Oracle Fusion vs PSFT

 

Hi Alex,

Great read on your Fusion article, just to let you know we just performed a 10 Month feasibility study on PeopleSoft or Fusion and we came up with the similar conclusions as per your article.

The only thing that bothers me, we could of donated that money to a worthy cause. I think we spent almost a million dollars if you tally up the employees like myself hourly rate and some consultants that were with us.

I have been in the IT field for 25 years, and the end game is always the same ;consultant come in make the money and leave after 3-6 months to the next project and the employees get the s**t for why we spent so much money, and the employees are stuck to show the value add of the 10 month feasibility project.

On a side note, I really enjoy your blog and thank you for the whitepapers.

 

Best Regards,

In the case above, we all sense some passion&frustration, I dont blame him they spent over 1 million dollars to go ahead to say that PeopleSoft 9 or Fusion can integrate to the current landscape of systems. Same answer as day 1. They’re study presented risks and returns associated with the project so the prospective managers can evaluate them. Again in their case they also believed their Finance and HRMS systems where so different compared to the norm and fell into a sales pitch of functionalities.

Here are some more examples of long feasibility studies that went the wrong direction:

1) ERP implementation , business functions inability of Hershey to ship candys for Halloween (The Feasibility study was 10 months)

2) ERP Implementation Nike Losing major shoe orders (The Feasibility study was 9 months)

3) Foxmeyers failure to process financial information and orders (The Feasibility study was 11 months)

4) BSkyB (BSY) got a 318 Million pound settlement in 2010 for a COTS system that did not work (The Feasibility study was 13 months)

5) UK Government scraps a 12 Billion National Program to provide integrated electronic records (15 Month Feasibility)

6) State of California spent 300 Million dollars in implementing a COTS software (12 Month feasibility study)

Here are some practical tips and guidelines:

  1. Use social media, an example when i wrote the article about Fusion and asked people to share their go live experiences i received 87 emails in 72 hours. These answers helped me understand quickly the different strengths and weaknesses of the product.
  2. In my view, The acceptable level for any business feasibility of a COTS package should not be more than 4 months, but the appropriate risk rate will vary for each individual depending on their personal work situation. Less experience teams usually require more time to complete a COTS Feasibility study.
  3. No SALES Pitch, focus on the integration, economic viability and operational zing of the project
  4. Don’t expect perfection in a feasibility study this is the main reason it should be short and done quickly.
  5. Bottom lines there are dozens of reasons why a feasibility study can't be done in a shorter timeframe, but perhaps only one why it can. It’s up to you to decide whether you are going to search for a way to do it, or regularly settle for a handy excuse. Some companies fall into the trap and use the feasibility study more like a sales pitch . Don’t do it!.

I am a big fan of the feasibility study but it should be a quick study and low cost exercise to determine if your COTS project (Commercial Off the Shelf Product) makes sense to adopt it within your organization.

 

 

 

Best practices in solution architecture for Oracle EBS, OBI, Hyperion Planning

Best practices in solution architecture for Oracle EBS, OBI, Hyperion Planning

A perfect design is an enemy of a good design. Often, we strive for a perfect design by customizing our systems, with what we currently know and forget quickly that the out of the box design may not provide the best solution to a given problem but it would probably have the best chance of meeting the schedule , regulatory compliance and cost constraints with acceptable quality.

I just completed US financial services solution architecture and noticing a trend with enterprise customers towards simplicity and making sure the business is provided tools to adapt to the new out of the box functionality reality. 2014 focus seems to be on essentials, mobile and providing a responsive design to the end user.

Having been lucky enough to have implemented multiple times EBS R12, Hyperion Products, OBI and CRM projects, I share some best practices on what in my view should not be modified and other areas that should be slightly improved from a business architecture standpoint:

 

Architecture OBI Hyperion  EBS

 

One question that comes often what is each product main purpose: here is a quick 1 liner on the products.

Hyperion Financial management is Oracle’s consolidation tool and statutory reporting

Hyperion Planning is the Strategic Planning, Budgeting and forecasting tool

Hyperion Financial Data Management is a tool to map different chart of accounts between source systems (EBS and non EBS applications) and HFM

Oracle EBS R12 is the ERP that store the Financial, Project, Procurement, Supply chain transactions

OBI Oracle Business Intelligence is the BI platform that stores the OLAP analytics, provides enterprise reporting, mobile BI and different scorecards.

When implementing your enterprise software keep in mind the following best practices:

1)  Times are changing; your approach to BI must change, Mobile Users Deserve the Same Quality of Browsing Experience as on your computer, one financial services company in the US is making sure most ERP, CRM transactions can be performed by mobile or tablet. Put in place mobile responsive design architecture when designing your solution. Your competitors are probably doing it or thinking about it. Technology has become the differentiator, not the business process.

2)  Capture integration requirements, then challenge all requirements that don’t respect the out of the box functionality, always make use of the product API’s to customize your solution if required. Focus on essential requirements only.

3) All enterprise software now integratre with Microsoft Excel, Microsoft’s classic spreadsheet program, is a favorite of sales and finance teams everywhere, use it to minimize change management

4)  One that I see often, not matching the growth strategy for the company to the capabilities of the system being implemented. Make sure everyone understands your functionality/ project scope and ROI to avoid the smoking mirror syndrome were the expectations and money spent do not correlate to the required outcome. Communicate with facts and data only!

Like usual please provide your thoughts and comments on solution architecture best practices.

 

 

Business Intelligence should not be Hype, use it to answer these 4 golden rules, I included an explanation of the OBIEE Design Architecture with step by step approach to building Reports.

BI should provide users the data and tools to answer questions that are important to running the part of the business you are responsible for

  1. Determine if the business is on track
  2. Identify where things are going wrong
  3. Take and monitor corrective actions
  4. Spot trends

 

Below is the OBIEE Standalone Architecture and an overview of its components

 OBIEE Architecture

  • Data Source --Contain the business data, users want to analyze. OBI supports Relational Database, OLAP databases, Flat Files, Spreadsheets, XML files etc .
  • OBI Web Server-- Provides the processing to visualize the information for client consumption.
  • Clients
    • Answers--Provides a self-service analysis platform for analytical needs.
    • Dashboards—Provides a way to organize related information for easy access.
    • Delivers---Used to create Ibots. Delivers alerts to subscribed users. It is integrated with dashboards and answers.
    • BI Analytical Server--- Provides efficient processing , generates dynamic SQL to query data base iin the data sources, structures results to satisfy requests.
    • BI Scheduler---Manages and executes jobs requesting data analytics. Schedules reports to be delivered to users at specified times.

Oracle Fusion Applications Workflow for Project Implementation & answers to questions received by e-mail on Fusion

 

 

We are now at release 6 of Oracle fusion applications (11.1.6), many questions have been raised on the implementation approach. Fusion don't forget is a combination of multiple Enterprise systems that Oracle acquired and yes Oracle took some of each to create Fusion.

Below is a visual diagram I created on the steps required to implement an instance of fusion applications:

 Oracle fusion apps implementaiton workflow

 

In general , it took me about 3 days to configure HCM and Financials, the functional configuration enables your Offerings and Functional Areas for implementation, and you select the Feature Choices, which typically enable you to integrate Offerings. Below is a screenshot

Question – What are some of the differences between EBS and Fusion Applications?

This questions comes often and people still believe no major changes exist,    below are 4 of them in the areas of Authentication, Authorization, Security and Segregation of duties.

 

E-Business

Fusion Application

Authentication

FND_USER

FMW(Fusion MiddleWare) OAM/LDAP

Authorization

AOL security model

FMW OPSS Oracle Platform Security Services

Security platform

Proprietary

FMW OPSS

Segregation Of Duties (SOD)

No functionality

Predefined SOD policies
Application Access Controls
Governor (AACG)

Question – In Fusion Applications Vision data does not exist anymore?

This is a common myth; here is a screenshot with some vision data

 fusion vision

Question 3 – Oracle Fusion Applications Documentation not available online?

Below is the link to Oracle Fusion Applications release 11.1.6

 fusion apps doc 11.1.6

http://docs.oracle.com/cd/E37583_01/index.htm

Oracle Fusion documentation is improving rapidly, it know include lots of detail with examples to help us take the right decisions.

 

 

Test drove for the last 6 months Oracle Fusion Applications, they have achieved Incredible Things, 7 Pros and 2 Challenges of Fusion Applications.

on Wednesday, 13 February 2013. Posted in fusion, Blog, Enterprise Architecture

Test drove for the last 6 months Oracle Fusion Applications, they have achieved Incredible Things, 7 Pros and 2 Challenges of Fusion Applications.

 

As most of you know for the past 6 months with some individuals in Palo Alto,CA. I have been testing, educating myself on the next generation of Oracle applications called Oracle Fusions Applications. What is Oracle Fusion Applications? It is inspired by the best of breed of Oracle’s application: Peoplesoft (HRMS), E-Business Suite (Financials), Primavera (Projects), JD Edwards (Manufacturing/Financials) and Siebel (Embedded analytics)

The question that everyone is asking should i stay on my current ERP or replace my systems with Fusion applications: (I must get an email every two weeks on this topic). Before i share my thoughts on this topic, let me share my experience for the last 6 months on the current version of the Fusion applications:

Pros

1)The response time is solid, look and feel is great.

 fusionalextest2147

2) They have incorporated a configuration setup workflow that makes it much easier to configure your module. Above screenshot I logged in with Fusion Functional Setup Manager (FSM) this is a one- stop shop for all implementation activities from planning to deployment. FSM is a separate module product, who manages all setups and all the various branches of products groups. Fusion includes FSM to allow implementation by others than the IT department or consultants. This includes plenty of checklists and simplifies the job of the project manager to setup and monitor the setup tasks as identified by Fusion itself. (Functional setup much quicker and easier to perform!)

3) What I appreciated the most was the export setup data, this functionality also allows users to easily migrate configurations from one instance to another (Test/ Production), works great did not encounter any major issues.

fusionalexexportsetups

 

4) Oracle Fusion Architecture provides an open architecture ecosystem, which is service & event- enabled.

5) Current present day applications have been on proprietary tools like People Tools, Forms, which require niche skill sets to manage and maintain.

6) Fusion has been developed; with Open standards based technology and is built on re-known Oracle Fusion Middleware (ADF, JAVA, SOA, BPEL, WEB 2.0 etc).

7) Currently CRM and HCM families are the most popular modules of Fusion, followed by Supply chain management (SCM).  Below are all the family products:

 fusionapplications

Where does PeopleSoft, EBS, Primavera, JDE and Siebel go from there? All these ERP’s had released a major version after the announcement of Fusion GA(General Availability), and there's no end in sight for future support(I guess until 2020). In fact, I think Oracle has good reason to keep these Enterprise systems going, even with Fusion now as an option.

I don't think Oracle is in a rush to try to get people to move to Fusion. PeopleSoft, EBS etc...They are very profitable business for them.

If you just look at PeopleSoft are far more profitable than Fusion precisely because the latter is so new. The dilemma for customers is when to opt for innovation over stability.

Oracle Fusion implementation can be done in 4 ways by

  1. Upgrading—Replacing an existing Oracle Applications instance with a new release (either a currently installed Oracle Applications version or Oracle Fusion Applications)
  2. Reimplementation—Treating an existing Oracle Applications installation as a “legacy system” and implementing some components of a live Oracle Fusion Applications installation or an entirely new Oracle Fusion Applications installation
  3. Coexistence—Adding Oracle Fusion Applications solutions to a customer’s existing Oracle Applications solutions, rather than upgrading or implementing new solutions in place of existing solutions
  4. Migration of data—Converting data from one Oracle instance to another Oracle instance by using Oracle’s Open Interfaces API and other Oracle or third-party conversion tools

I am strong believer of co-existence strategy and architecture for Oracle E-Business Suite, PeopleSoft, JD Edwards and Siebel apps and Fusion, for the following 3 reasons:

1- Risk mitigation, Fusion applications is still in my view a new product

2- You require revamping your technology skills within your organization to extend, maintain and support the various components of Oracle Fusion Applications here is my short list (A coexistence strategy can help you slowly adapt with the change of technologies):

  • SQL, PL/SQL, JAVA & java script
  • XML – Extended Markup Language
  • CSS – Cascading Style Sheets
  • XSL – Extensible Style sheet Language
  • ADF – Application Development Framework
  • JSF – Java Server Faces
  • Web Services
  • BPEL – Business Process Execution Language
  • AIA – Application Integration Architecture
  • Web Center
  • BI Publisher
  • OBIEE – Oracle Business Intelligence Enterprise Edition
  • Hyperion Essbase
  • WebLogic Server Administration
  • Oracle Identity Management

3- Most corporations have invested significant money in their current technologies, and will require a strong business case with facts and numbers on the added value of going to Fusion in a big bang approach.

Interest will remain high with Fusion applications and my predictions in the next 5-8 years everyone will be on Fusion similar model like SAP. Why 5-8 years? Most corporations require lots of inter connections to other systems (spider web architecture) and have invested in significant customizations to meet the corporations global business requirements.

My overall experience with the Fusion applications exceeded my expectations. Would appreciate to hear from clients and others that are live with Fusion.

9 ways to reduce cost and maximize value on User Productivity Kit (UPK)

on Sunday, 10 February 2013. Posted in Business Analysis, Blog

9 ways to reduce cost and maximize value on User Productivity Kit (UPK)

 

What is UPK?It is a software tool that can capture all the steps in a system process. It records every keystroke, every click of the mouse, each menu option chosen and each button pressed. All this is done in the UPK Recorder by going through the transaction and pressing “printscreen” after every user action. From this, without any further effort from the developer, UPK builds a number of valuable outputs

All major ERP/Enterprise  players have their own version (PSFT, EBS,JDE, SAP, Siebel) perhaps one of the less well known of the software products on the price list, however just a brief consideration of its name indicates that it may be of considerable value to organisations. We invest significant money and resources in the purchase and implementation of software applications but do we realise, in practice, the levels of productivity that we would like to have and that will bring the full return on our investment? 

Here are some tips to help you reduce costs:

  1. These tools have become quite easy to manipulate you don’t require a centralized group, de-centralize function these packages have become mainstream. De-Centralize the use of these type of packages.
  2. You invest more than time and money when you decide to go with a UPK package. You are, in essence, investing in a product to explain and handle your business processes. With everything that you spend (time, money, and effort) learning the system, Negotiate hard with your vendor, Your goal should be to pay the right price and not what the vendor is telling you, I have seen clients get substantial savings on these type of products. The downside once you are committed to the UPK system even if it is not entirely suited to you and your staff. This makes it unlikely that you'll switch to a new system, even if that system might work better, because you've just spent so much time incorporating it into your organization. Change is expensive.
  3. If you buy use it throughout the whole project lifecycle, as recommended below:Snap 2013-02-10 at 14.56.20

 

Were it adds value to your implementation:

4) Users learn and absorb the new application and procedures much easier through the many training tools available through UPK.

5) Quality assurance testing is made simpler and virtually seamless by capturing test case scenarios using the Oracle UPK.

6) Process documentation is completed almost automatically by utilising UPK.

7) When creating your content always have the training plan in mind, and it should always address these points:

Learning objectives

Training and delivery approach per module

Audience per module

Course curriculum

Course schedule

Assumptions

8) ROI on UPK is usually delivered quickly, it will help you standardize application throughout the organization and help you reduce test script creation time and reduce documentation time

9) Maintain your walk away power. It is better to walk away from a not interesting price rather than making too large of a concession, that your organization will regret later.

Finally in my experiences, UPK can output Instructor manuals, student guides and quick reference cards directly from the same single recording exercise. The efficiency that can be gained across the project is obvious in terms of a single recording and development exercise supporting so many project activities. UPK could be financially justified on the generation of test scripts alone for a medium to large implementation. 

When it comes to supporting major application implementations, there is no substitute for experience. Hire people with experience to help you design your UPK strategy and deployment.

 

Test drove Oracle Exadata with Oracle GL Financial Analytics, the pros/cons, and vision to embrace it within your blueprint

on Thursday, 17 January 2013. Posted in Enterprise Software , Blog

 

 

Oracle’s vision is clear with Exadata , it integrates by design with other Oracle products like Enterprise manager 12c and a game changer in performance.

Exadata came from the Sun Microsystems acquisition; this has proven to be a strategic acquisition. Sun technology enabled Oracle to become one of the leaders in the highly profitable engineered system segment of the hardware business. I believe that products like Exadata and the SPARC SuperCluster will not only continue to drive growth for their hardware business but force the titans to innovate instead of executing.


The vision for the 4 titans SAP, Oracle , IBM and Microsoft is to offer their clients, an option to be in command of all layers of their clients technology stacks, “One Throat to Choke” principle. This is an expression used in business to describe the advantage of purchasing goods or integrated services from a single vendor. That way, when something goes wrong, there is only “one throat to choke.”

Also I believe in the future (next 24 months)the licensing agreements will begin a new phase of bundling hardware and software together.

 I had the opportunity with some folks in California to test drive Exadata. I was impressed the Exadata X3 (X3 stands for third Generation) is a real game-changer, as far as data is concerned, the combination of the huge on-board flash memory with the benefits of Hybrid Columnar Compression, meaning that you could store at least 200TB of data in memory on a full rack of Exadata X3. In other words you should never have to hit spinning disks for your data again.

We installed Oracle financial analytics with GL (General Ledger) and used the 5 interactive dashboards of GL to test Exadata. The financial dashboards were:

1-Profit and Loss

2-Expense

3-Balance sheet

4-Cash Cycles

5-Liquidity

Below is the look and feel of the GL financial dashboards:

 

oracle financial gl interactive dashboards

 

Pros

 1)We pushed the Exadata machine to 100 000 transactions per seconds with no wait as you see below the dark blue color is the user I/O, no latency. Flash Log and machine performance was exceptional.

 

Exadata Output

2)Exadata has a Hybrid Columnar Compression (HCC) is a feature introduced in Oracle Database 11g Release 2 which Oracle allows to be used on Exadata storage, in our testing we had an uncompressed database of 75 Gigabytes, and by using the compression advisor functionality it was reduces 20 times to 3.8 Gigabytes. This feature impressed me the most; it is less talked about , should produce a significant savings on storage.

3)Seamless Integration with Oracle Enterprise Manager, it comes with 3 views Hardware, Software/System and a configuration view that summarizes all components with patch recommendation. (Here is a white paper link that explains the integration in detail.) http://www.oracle.com/technetwork/oem/exa-mgmt/exadata-mgmt-twp-1662642.pdf

4)The adoption of Exadata will necessitate a revamp of the IT support roles to make this single group responsible for the entire frame from storage to the database.

The Exadata machine administrator will need to be versatile and knowledgeable in different areas: Here are my thoughts on the breakdown of the role:

55% Database Administration
25% Cell Administration
10% Linux or Solaris Administration
10% Miscellaneous (Infiniband,other...)

 

Cons

1)Oracle Exadata x3 being a new product has a small footprint and the competition especially from the other titans is ferocious, business case must be thorough, I think best approved using an enterprise consolidation project of many environments, the business case must identify the extent of the existing Information System problems and show a roadmap moving towards a private cloud.

2)The Oracle Exadata, SAP Hana and IBM Neteeza all have similar architectures no ‘wow’ differentiator between them To learn more on this product line, here are some links to help you get started:

My next entry will provide you tips and tricks in using Oracle's Unified methodology (OUM) for your project and make my first video on this topic.

I received many inquiries asking me about the technical details of this website: Here are the specifications: The website is built with Joomla 3.0 (open source), database is MySQL, The server is a virtual private server, Operating system is CentOS6(based on Linux) with 2GB RAM and 60GB of Disk Space.

 

 

Service Oriented Architecture (SOA)

on Tuesday, 01 January 2013. Posted in Solution & Business Architecture, Blog

SOA will dramatically change our working environments. Oracle SOA suite is the beginning of standards-based applications that are secured, managed and governed , and are spawned

by changes like Mergers & Acquisitions, regulatory compliance, and increased competition.  

With this in mind, we introduce the concept of a Service Oriented Architecture (SOA).

 

What is SOA it is a design blueprint for applications within an enterprise.
 

 

Corporations will adopt SOA, to increase their business agility, for faster response changes, increased technology asset reuse, reduced integration expenses, reduced business risk & exposure

The ability of SOA to change, evolve, and manage business processes throughout an

enterprise is changing the way IT works. SOA is enabling IT to operate as a

business unit. Alignment and accounting for IT investments is now based on business

strategies and transactions. SOA in an enterprise will identify and highlight

business dependencies and encourages cooperation and communication between

business units and IT.

 

SOA uses Services. Corporate applications evolve into organized collections of what are

referred to as “business services”. Looking at these applications from a service

orientation perspective closely maps to business initiatives and processes. So a

service can be payroll, or extending credit, or adding a new customer—it’s no longer

only a technical transactional process.


A well architected SOA provides top to bottom management visibilityof existing web services, so one doesn’t go on a “scavenger hunt” for any given

application. A SOA provides for a more rapid method of distributing applications and

increased agility. By leveraging, and the reuse of existing enterprise software,

infrastructure, and networking/bandwidth, the costs of custom integration and

interoperability are lowered. Manual tasks are reduced or eliminated. Compliance

within an organization’s industry is accomplished by exposing business

processes and reducing risks. For even greater cost savings, these

business services are reusable for many different applications both within and outside

of the enterprise without costly changes.

Most corporations have started to plan and implement a SOA adoption.

OUM differs from the AIM Methodology

on Tuesday, 01 January 2013. Posted in Business Analysis, Blog

A person asked a very good question at this year’s OpenWorld, how OUM differs from AIM in term of methodology and deliverables?

AIM retirement date was January 31, 2011.  Going forward, OUM supersedes AIM.

One of the big advantages it know entails BI and EPM projects within the methodology and follows Oracle’s strategy  to bring all applications under the same methodology and in v5.3 it know includes PeopleSoft, JDE and Siebel products.

OUM is an iterative methodology it follows best practices. An iterative approach embraces requirements change by building processes into the project that allow for refining requirements while also maintaining a strong focus on cost and scope containment.

Since OUM is an iterative approach to implementing software systems, it is essential that practitioners first understand the concepts of iterations “Think a little - do a little. Think a little more – do a little more.”

Below is OUM Implement Core Workflow View was created to identify the core tasks within the Implement Focus Area. This view should serve to accelerate the understanding of OUM by new practitioners and help to keep project teams focused on these tasks. The delta with AIM is of medium complexity.

OUM emphasis in on a graphical representation, this is done intentionally since we all know that text can be misinterpreted. Below is an example that comes with the System Context template of OUM (Deliverable RD.005)

The Above System Context Diagram is a graphical representation depicting the boundary of the system and its association with external entities called actors.  An actor can be one of 4 types (i.e., human, another system, a clock representing a time-based event, or a hardware device).  These actors have the ability of sending or receiving information and/or events into or out of the system.  The key information represented on the association line between the actor and the system is at a summary-level and shows an arrow indicating the direction of the information flow.

Oracle Partners meeting the access requirements described (You must be an Oracle Gold partner unlike AIM were it was readily available) to obtain the OUM materials.  To access the method pack, related collateral, and training courses:

OUM obliges a standardization of implementations across all Oracle products a good thing in my view , you can also tailor OUM to support your specific project situation. With its ready-made templates, guidelines, and scalable work breakdown structure,the emphasis on graphical representation and the iterative approach are the main improvements over AIM.
