Identify Roles for each task/activity throughout the project schedule

Consider the number of resources (testers) available for the project. If the resources are new hires, consider the time for training and their skill level.

Once completed, submit the estimate to the project management team.

By role and phase of the lifecycle, identify key tasks so that a bulk of the work is accounted. For initial estimates, the numbers are "rough" and there will be opportunities to refine the estimates in a later phase of the lifecycle.

If new technology or tools are being implemented, consider the learning curve and training in estimates. Consider the third party dependencies, if any.

Review appropriate documents, notes, and artifacts that help in determining time and resources required to complete identified tasks and activities.

For each role and each task assigned to the role, define the amount of effort (in hours, or days as requested by the project manager) requried to complete each task.

Prepare Performance Test Effort Estimates using Performance Test Effort Estimation Template.

Communicate the total effort for each domain to the project manager for further development of the project plan or project schedule.
