Have they developed Word and other templates for documents created during SDLC? In three of my most recent positions, the stress was on completing the documents according to schedule, rather than emphasizing the work. The work involved cataloguing requirements, analyzing them and developing a good design document, and thoroughly testing the resulting code. When I first started programming in SAS® , I was lucky to get any users requirements at all; it was always “I’ll know it when I see it.” But with the emphasis on the documentation, and not on the analytical work behind them, the project still falls behind schedule because of missed requirements. If the requirements are not thoroughly complete when coding begins , it is likely to fail in the testing phase, especially if the independent test team gets abetter, more complete version of the requirements than the development team. We discuss the work that is involved in detail for producing sound requirements, design, and testing protocols. Consider the retirement of legacy software as part of the SDLC.  \nINTRODUCTION  \nPHASES  \nThe exact naming and components of the phases can vary and are adapted to your company’s specific needs and adjusted to the scope of the project (Fulton 2003) .  \nTraditional view of the SDLC is a waterfall approach. One phase keys off the end of the previous phase.  \nFigure 1 : Waterfall Approach  \nFigure 2: Iterative Process  \nA more flexible and accurate description is of an interative process. No one ever gets it exactly right the first time and an iterative process depicts this.  \n1  \nSAS Global Forum 2012 Planning and Support  \nPLANNING  \nIn this phase, the background and scope of the SAS and other programming to complete the project are  \nFigure 3: Gantt Chart  \nestimated. This is done to determine the size and level of effort, staffing plans and budget. The project goals are set, and roles and responsibilities are identified. A project plan for performing the work and managing the project is developed. This should include tasks, schedules, and assignments. The project management will be implementing tracking and oversight mechanisms, configuration management activities, training, and a test plan / strategy. (Helton 2002) At this phase, documentation and validation that will be required are developed.  \nThese efforts may be described as “proof of concept.” The job is to identify risks and risk assessment of assumptions and identify the critical path (CPA) of the work. The critical path is often identified using software such as Microsoft Project. Within a project the final project plan is often in the form of a Gantt Chart (using Microsoft Project or other software for projects of medium complexity or an excel spreadsheet for projects of low complexity) .  \nThe benefit of using CPA within the planning  \nprocess is to help you develop and test your  \nplan to ensure that it is robust. Critical Path Analysis identifies tasks which must be completed on time for the whole project to be completed on time. It also identifies which tasks can be delayed if resource needs tobe reallocated to catch up on missed or overrunning tasks. The disadvantage of CPA, if you use it as the  \nFigure 4: Critical Path Analysis  \nSAS Global Forum 2012 Planning and Support  \ntechnique by which your project plans are communicated and managed against, is that the relation of tasks to time is not as immediately obvious as with Gantt Charts. This can make them more difficult to understand.  \nA further benefit of Critical Path Analysis is that it helps you to identify the minimum length of time needed to complete a project.
