6 - PROJECT TIME MANAGEMENT

continually assess backlogged task-value to maximize value for customers. On-demand scheduling is
often used for projects that evolve the product incrementally in operational or sustainment environments,
and where tasks may be made relatively similar in size and scope or can be bundled by size and scope.
This approach may use classes of service to allow flexibility in resource utilization, ensuring that critical
or time-sensitive tasks are fast-tracked, while less schedule-critical tasks are perhaps delayed but not
put off indefinitely. The goals of on-demand scheduling are to minimize the time taken to accomplish
work, to minimize estimation activities, and to maximize the value of work accomplished.
• Portfolio management scheduling. This method involves scheduling of projects based on prioritizing
investments in software as established by criteria determined at the organizational level. Scheduling 6
of projects and the activities within projects are not based on the size or scope of the work but rather
on importance to the organization. Scheduling based on portfolio management is determined by value
created for the organization vs. the time and/or cost of a development project. This method is often used
for strategic management of large enterprise systems or commercial services.
Figure 6-1 provides an overview of Project Time Management for software projects.
