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 ]
Very often, software projects start with an existing baseline that contains the project in its prior version and depending on the project, many of existing software modules and components are reused, which reduces development and testing time, therefore, increasing the probability of delivering a software project on schedule.
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 scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.
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.
Analyzing progress compared to the baseline schedule is known as earned value management. [5] The inputs of the project planning phase 2 include the project charter and the concept proposal. The outputs of the project planning phase include the project requirements, the project schedule, and the project management plan. [6]
Time management may be aided by a range of skills, tools and techniques, especially when accomplishing specific tasks, projects and goals complying with a due date. [ 3 ] Initially, the term time management encompassed only business and work activities, but eventually the term comprised personal activities as well.
If that activity time is for the first work center, then schedule the job first. If that activity time is for the second work center then schedule the job last. Break ties arbitrarily. Eliminate the shortest job from further consideration. Repeat steps 2 and 3, working towards the center of the job schedule until all jobs have been scheduled.
