In tracking and reporting progress to manage a schedule, the project manager must know how the work is progressing compared to the schedule master and if necessary, make changes to keep the progress on time. Tracking the schedule performing involving measuring the work performed against work expected to be perform with given expenditure of resources and periodic reporting on the progress of the project , provide the project management team with information and data using diagrams, pie charts and graphs management system. Reporting percentage is completed by or to determine the percentage of the project that has been completed , the project manager must determine what to measure because some percentage are misleading for example the project that has been completed 25 percent does not mean that the project is 25 percent complete and if labor is used as a units of measure, the percentage of packing is even less because more time is estimated to pack each item in the kitchen and the unit of measurement is related to the type of the project like software are line of code written . To measure a project using a milestone provide an important opportunity to the project management team to focus on the completing the activity on the schedule on complex project as useful tools for communicating important dates to the entire project teams. Project team member can now adjust their effort to complete the project to meet the milestones. To inform a stakeholders, a schedule update is distributed regularly to provide the project stakeholders with an assessment of progress of the project against on the master schedule. To understand the resource leveling, the management of schedule activity is constrained by the availability of the resources. To accelerate the schedule ,the project manager must know how to accelerate schedule to compensate for unanticipated event that delay critical activity. the project manager. Compressing or crashing the schedule are technique or the term use by the project managers to shorten a project schedule: Contingency resources,is the extra time, or buffer time or reserved time that is build on the schedule. Method of accelerating the schedule is to add activity on the critical path that are empty or that are operational. Reassessing resources . Activity that are not non critical path,that have free float can be delayed without delaying the end date of the project if they start by start late date and the project manager can divert some resources from activity with free floats to the activity on the critical path without delaying the project completion. Changing scope, the unit cost of the work to be performed on a project is calculated at the beginning of the project based on the execution strategy of the project to meet the project completion date. If the project completion date is move up, then the unit cost is likely to increase and to save money a project team up to extends the project end date to avoid paying overtime and normal labor rate from the project schedule. Additional resources, Another option is to allocate fund that can be used to add resources if necessary can be increased by adding overtime to the schedule calendars by hiring additional contract workers and renting additional equipments. Changing quality. Another option for accelerating the schedule is the changing of the quality of the specification of the projects. This usually done as a scope Change. The progress can be measured be determine the percentage of resources, expended completion of activities by schedule dates, milestone achieved or fraction of activities accomplished. The Standards used to measure progress particularly when partial payment is made to the contractor is made a concerned and should be specified in the contract document. Resource leveling is reallocating people and equipment to remove period of overuse or under use . Unplanned delayed and cost can be anticipating by including contingency time and budget amount where needed to keep the schedule on time. Resource allocation and resource calendar should be examine to determine if the resource is over committed. Free Float can be used to delay non critical activities that use the same resource to locate its time more evenly. If there is any need to accelerate, schedule,activities that are not on the critical path can be delayed using their free floats and their resources can be move to activities on the critical path to complete the same sooner. Contingency resource can be committed to speeding up the activities. If necessary the scope can be changed to bring in additional resources or lower the quality.
