start and finish considering its predecessor activities. A strategic project usually has scope as its most critical issue, while a tactical project has schedule, cost, or a different set of scope as the primary constraint. The difference in the latest and earliest finish of each activity is that activity's slack. The critical path activities that directly impact the completion time. Note that open-source software "projects" (for example) may lack defined team-membership, precise planning and time-limited durations. It is common practice to specify optimistic times to be three standard deviations from the mean so that there is approximately a 1 chance that the activity will be completed within the optimistic time. Some analyses of project-oriented activity distinguish - using military-style terminology - between grandiose strategic projects and more trivial or component operational projects: tactical projects.
Further information (please click Evaluation Criteria. Estimate Activity Times, weeks are a commonly used unit of time for activity completion, but any consistent unit of time can be used. Please note that a final evaluation needs to be undertaken before completion of each project or programme. They can be formulated as smart criteria : 9 Specific Measurable (or at least evaluable) achievement Achievable (recently Agreed to or Acceptable are used by whom? These are projects that have one operational goal, which probably does not entail contributions by most employees within the organization. Type of evaluation.1) Mid-term and/or final evaluation;.2) Independent Project Evaluation or In-Depth Evaluation;.3) Rationale for this choice. If activities outside the critical path speed up or slow down (within limits the total project time does not change. Construct the Network Diagram. Compare: Hundhausen, Richard (2006). The underestimation of the project completion time due to alternate paths becoming critical is perhaps the most serious of these issues.
