Estimate Based on Experience

• Estimate based on how long it took to complete a similar task.
• Consider other development tasks for the scenario or quality of service requirement and the integration costs.
• Factor in the cost of writing unit tests.

2

Balance Load

• If the estimate creates more work than can be accomplished in the iteration, work with the project manager to load balance the task or move to another iteration.

3

Refine the Task

• Examine the development task in the context of the other development tasks for any parts of the scenario or quality of service requirement that are not yet covered by a development task. Create new development tasks to cover these areas.
• Assign these new tasks to the appropriate developers.
• Work with the project manager to add new development tasks to the iteration plan.

4

Define the Integration Points

• Work with the other development team members to establish a clear understanding of how this functionality will integrate with other functionality.

All development tasks for the iteration have a development cost.
