A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
The project has two critical paths: activities B and C, or A, D, and F – giving a minimum project time of 7 months with fast tracking. Activity E is sub-critical, and has a float of 1 month. The critical path method ( CPM ), or critical path analysis ( CPA ), is an algorithm for scheduling a set of project activities. [ 1 ]
Local (basic block) scheduling: instructions can't move across basic block boundaries. Global scheduling: instructions can move across basic block boundaries. Modulo scheduling: an algorithm for generating software pipelining, which is a way of increasing instruction level parallelism by interleaving different iterations of an inner loop.
PSP0 has 3 phases: planning, development (design, code, compile, test) and a post mortem. A baseline is established for current process measuring: time spent on programming, faults injected/removed and size of a program. In a post mortem, the engineer ensures all data for the projects has been properly recorded and analysed.
A Gantt chart is a type of bar chart [4] [5] that illustrates a project schedule. [6] This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. [ 4 ] [ 7 ] The width of the horizontal bars in the graph shows the duration of each activity.
The project schedule is a calendar that links the tasks to be done with the resources that will do them. It is the core of the project plan used to show the organization how the work will be done, commit people to the project, determine resource needs, and used as a kind of checklist to make sure that every task necessary is performed.

The Graphical Path Method (GPM) (formerly known as the ‘Graphical Planning Method’) was originally developed from 2004 to 2006 by Dr. Gui Ponce de Leon, current Chairman of the Project Management Institute College of Scheduling (PMICOS), and was first presented at the PMICOS 2008 annual conference.
