The Linear Project Management Life Cycle (PMLC) model is the simplest and the most innate of all the project management approaches. This approach assumes that you have all the information needed for the projects goal and solution. The Linear PMLC does not accommodate modifications and/or deviations well. Deviations, such as scope changes, can cause major turmoil in the project schedule. The Linear PMLC consists of the five process groups, each performed once in the following sequence: Scoping, Planning, Launching, Monitoring and Controlling, Closing. The completed project is not complete until the Closing process is executed. Also, each process group must be completed first before the next process group can begin. The Linear PMLC model works best with project that have the following characteristics: • Complete and clearly defined goals, solutions, requirements, functions and features • Few expected scope change requests • Routine and repetitive activities • Use of established templates The strengths of the Linear PMLC model include: • The entire project is scheduled at the beginning of the project • Resource requirements are known from the start • The Linear PMLC model does not require the most skilled team members • Team member are not required to be co-located The weaknesses of the PMLC model include: • Does not accommodate change very well
Unformatted text preview: SYSTEMS DEVELOPMENT LIFE CYCLE 3 A systems development life cycle is a framework for describing the phases involved in developing information systems. There are a variety of popular SDLC types that have evolved over the years. Each type has its strengths and weaknesses, and each methodology is best suited to the specific kind of project needs. The SDLC methodology types are as follows: • Waterfall • Prototyping • Incremental • Spiral • RAD (Rapid Application Development) The Waterfall has a well defined linear framework. The project is divided into sequential phases (i.e., initial, requirements, design, coding and testing, implementation, Operation/Support). SYSTEMS DEVELOPMENT LIFE CYCLE 4 References Wysocki, R.K.
