How to estimate task duration

Providing realistic target dates for tasks and projects can be a complex task. The Project & Work Facilitation Unit recently added the Task Estimation Matrix to ASR’s Project Management Resources folder to make it easier to consider the external factors that will impact your timeline.

The Task Estimation Matrix was reviewed in a recent Project Management Round Table, and attendees offered tips for using the matrix effectively.

• Break tasks down into smaller units of work before assessing the complexity and risk
• Clarify roles and dependencies 
• Ask people familiar with performing tasks for their feedback on how long it typically takes to complete a similar task
• Have a team assess the risk and complexity of tasks together. Compare responses and discuss discrepancies. Having more input will shine light on complexity that you may not have otherwise considered.
• Think of estimates in terms of hours first, then translate hours into target dates. Remember to project timelines based on productive working hours. This will not be 8 hours. Depending on the production support or administrative duties of the staff involved, this could be 6 or fewer hours.
