SPEC - Project Management Terminology, resources are required to carry out the project tasks. They can be people, equipment, facilities, funding, or anything else capable of definition required for the completion of a project activity. The lack of a resource will therefore be a constraint on the completion of the project activity. Resources may be storable or non-storable. Storable resources remain available unless depleted by usage, and may be replenished by project tasks which produce them. Non-storable resources must be renewed for each time period, even if not utilised in previous time periods. Resource scheduling, availability and optimisation are considered key to SPEC’S successful project management.
Allocation of limited resources is based on the priority given to each of the project activities. Their priority is calculated using the Critical path method and heuristic analysis. For a case with a constraint on the number of resources, the objective is to create the most efficient schedule possible - minimising project duration and maximising the use of the resources available.
