6.4 Estimate Activity Resources

6.4 Estimate Activity Resources itto



Estimate Activity Resources is the process of estimating what you need to complete each activity or task. Generally we’re considering human resources (linking to the activity durations and the planned schedule), but we can also consider the physical resources required such as equipment or supplies where necessary (linking to procurement).

Estimating the human resources required is closely linked with Plan Human Resource Management. When estimating the resources required you will likely need inputs from other teams such as internal project resources to provide support for test activities, BAU to provide testers or to review business scenarios, etc. Not only will you need to estimate the resources that you require but you’ll also need to consider the impact on their “home” team and ensure that their estimated time is managed carefully.

Each activity identified in the previous processes (6.2 Define Activities and 6.3 Sequence Activities) should initially be allocated to at least a team, and preferably an individual, to allow for accurate planning and ownership of tasks – at a minimum you should at least identify the type of person required to fulfill the task (for example, a business subject matter expert in a particular functional area). When allocating each activity bear in mind the skill level of the person allocated and what support they might require, their location, any calendar issues (both personal and statutory holidays or working patterns), and any local regulatory implications (for example, local laws on working weekends or hours of work).

Link in where possible to already-defined resource plans. For example, if seeking people from the business their managers may have already allocated staff to a project “pool” that you can call upon.

The outputs from this activity will form your resource requirements. Your project plan can be updated with all required resources, and any resource calendars can be updated with your requirements.
