Capacity Analysis

Capacity of a team is the measue of the team's availability for work per iteration.
Most common method of estimating the capacity is:
Capacity = #People x iteration duration x availability factor.

 Availability is the fraction of the time that an individual team member can spend, in a given duration. This is also called Focus factor.
As before, point = 1 person-day = 8 person-hours.

Steps to calculate Capacity:
- Determine available time for a team in an iteration (available person-days - overheads)
- Determine people (resources) in the team effectively available for the iteration (excluding PTOs etc)
- Per-person capacity = focus factor * (person-days - PTO)
- Per-team capacity = sum of all per-person capacities

Let's take an example. Let's assume following:
Working days in an iteration = 5
Working hours in an iteration = 40
Hours spent in meetings and stand-ups = 8
Hence,
Net working hours available = 40-8 = 32 hours
Net working days available for the iteration = 32/8 = 4 days

Let's say, there are 5 people in the team.
PersonA's availability factor = 25 %. Hence, PersonA is available for 32*25% = 8 hours
PersonB's availability factor = 50%.  Hence, PersonB is available for 32*50% =  16 hours
PersonC's availability factor = 70%. Hence, PersonC is available for 32*70% = 22.4 hours
PersonD's availability factor = 55% Hence, PersonC is available for 32*55% = 17.6 hours
PersonE's availability factor = 60%. Hence, PersonC is available for 32*60% = 19.2 hours

Total of the individual hours = 83.2
Hence:
Total hours available for the team for the iteration = 83.2 hours
Points available = 83.2/8 = 10.4 points.
Team Resources = Team hours / Iteraion hours = 83.2 / 32 = 2.6
