The basic SDLC has seven phases such as Concept, Requirements, Design, Implementation, Release, Operation and maintenance and Decommission. The new phases which have been evolved over the last two years called the replacement and disposal phases are not identified to the SDLC as separate phases; however, they are adapted and included to the SDLC. According to the SDLC methodology, step 5 which the old system gradually replaced when the new system can phased in is in the Release and Operation phase.
At same time, Entrance and Exit Criteria have also been introduced for each project phase. Entrance and Exit Criteria are checkpoints and should be clearly identified by key points as follows:
• Exit Criteria from a project phase is dictated by the needs which is Entrance Criteria of the next phase.
• Each project phase transition is made up of people who those providing information from the previous phase and people who those receiving information from the Providers for the present phase.
• Validation of Exit Criteria is confirmed by the Receivers such as,
1. A Checklist organized as a set of questions and proofs.
2. Verification and review of supporting documents.
3. Evidence has been stored in an approved repository.
4. Signature of acceptance by the receiver.
• Key measurements to evaluate effectiveness of process and condition of artifacts and distribution information can be part of the Exit Criteria.
Here are some examples of entrance and exit criteria for SDLC.
Concept phase
- Entrance
Draft business case and system concept
- Exit
Provide summery of concept phases process.
Requirement phase
- Entrance
- Exit
Prior to the planning phases, established performance goal and identified cost, schedule
benefit and risks should be planned and documented.
Each phase has entrance and exit criteria to connect to next phases. These way criteria are clear and organized what need to be done. I think that the system approach is been adapted to the SDLC from these evidences.
Can this apply for the integration of the accounting and the cash cycle into the SDLC? Yes, because SDLC makes system clear, especially accounting and handling cash is needed to be organized in order to not making any mistake. Accuracy is one the most important characteristic of accountants. During my searching, I found the article about financial service firm which chosen to set up PMO process for project management, SDLC and project office dashboarding. http://www.botinternational.com/20070223.htm
Also I saw some job posting combined with financial or accounting and SDLC. http://jobview.monster.com/getjob.asp?JobID=63685822&JobTitle=Oracle+Developer+-+E+Business+Suite+11i&q=system+development+life+cycle%2c+accounging&brd=1&cy=us&vw=b&AVSDM=2007-10-12+12%3a24%3a00&pg=1&seq=2
Here are some examples of exit criteria used in accounting.
• Summarize the overall of the plan and determines needfulness.
• Identify the risk and benefit, schedule, time and budget.
• Consider accounting life cycle and chose the best design
• Find any alternatives and reanalyze if needed.
• Make sure it works properly and efficiency. Alternative calculation for cross reference.
• Pick the sample for auditing and maintenance purposed.
• If satisfy whole life cycle, then system project closed.
As a result of my searching, I could say that SDLC is totally adapted in accounting environment and this two together makes more effective management system and brings great benefit to the firm.
