Projecttime management



Importanceof activity sequencing

Theprocess of identifying and recording the logical relationships amongscheduled tasks is referred to as activity sequencing. Activitysequencing is of great importance to project managers in the sensethat, the dependencies exhibited among projects in a network analysiscontrol the directors’ ability to make changes to the time scheduleduring the actual execution of the activities. Underestimating theimportance of activity sequencing implies that most tools andtechniques won’t work since the manager ignored variousdependencies among activities.

Activitysequencing enables project managers to estimate the longest and theshortest time possible it would take to complete the project. Throughthe process of crashing, managers can be able to trade off betweentime and cost and come up with the most optimal time to complete theproject and the associated minimum cost.

Estimatingactivity durations versus estimating the effort required to performan activity

Everyactivity in a project has three attributes which include: Resourcesneeded, its length and the work effort. Estimating activity durationsinvolves analyzing each and every task and determine how long itwould take. In most cases there are three-time durations: Thepessimistic time duration, the optimistic time length and the mostlikely time duration of each activity. The average of thesethree-time durations will provide the exercise period. However,estimating time length takes place only after determining the amountof work and resources needed per activity. Estimating work effortinvolves detailing all work related to performing the task andestablishing the amount of work effort each employee has to invest.To determining work effort, one has to lay down all the availableexpertise their level of skills and compare with the technicality ofthe project
