Explain Network Planning Model

These project scheduling techniques model the project's activities and their relationships as a network. In the network, time flows from left to right. These techniques were originally developed in the 1950s - the two best known being CPM (Critical Path Method) and PERT (Program Evaluation Review Technique). More recently a variation on these techniques, called precedence networks, has become popular and it is this method that is adopted in the majority of computer applications currently available. All three methods are very similar and it must be admitted that many people use the same name (particularly CPM) indiscriminately to refer to any or all of the methods

Explain objectives of Activity Planning

  Feasibility assessment :-It is not until we have constructed a detailed plan that we can forecast a completion date with any reasonable knowledge of its achievability. The fact that a project may have been estimated as requiring two work-years effort might not mean that it would be feasible to complete it within, say, three months were eight people to work on it - that will depend upon the availability of staff and the degree to which activities may be undertaken in parallel. Resource allocation:- The project plan allows us to investigate the relationship between timescales and resource availability (in general, allocating additional resources to a project shortens its duration) and the efficacy of additional spending on resource procurement. Detailed costing:- After producing an activity plan and allocating specific resources, we can obtain more detailed estimates of costs and their timing. Motivation :-Providing targets and being seen to monitor achievement against targets is an effective way of motivating staff, particularly where they have been involved in setting those targets in the first place. Co-ordination :- The project plan, particularly with large projects involving more than a single project team, provides an effective vehicle for communication and co-ordination among teams.

What is software prototyping?

A prototype is the working model of one or more aspects of the project system. It is constructed and tested easily and inexpensively in order to test our assumption. Prototype can be classified in to two ways. Throw away prototype Evolutionary prototype Throw away prototype: the prototype tests some idea and then discarded with the true development of the operational system is commenced. The prototype could be developed using different software and hardware. Evolutionary prototype: the prototype is developed and modifies until it is finally in a state where it can became the operational system.
