Estimate Activity Resources

Estimating the type and number of resources required to perform the identified activities. You may be thinking that why the sequence activities process is earlier than this process. From our experience, we know that the activity’s sequence impacts the type and number of resources required. If two activities A & B, which are of similar type and can be completed by one resource, has must be done in parallel then you need two resources otherwise taking only one resource on the project could have helped us complete the work on time. This is the impact of determining sequence on resource estimation.
When you are estimating resources (the first time), that time you do not look into your resource pool that how many people you have. But look into the nature of the activity and determine how much minimum you need. You should not focus on time or resource optimization. Do not look into how many resources are required to complete the work in 2 days. Just estimate for this kind of activity what type of resources and how many are required to complete the activity.
