Williams' Study, Continued

Time to complete first three assignments

Assignment	Group	Elapsed Time	Total Time
Program 1	Individual	100%	100%
Program 1	Pair	80%	165%
Program 2	Individual	100%	100%
Program 2	Pair	57%	114%
Program 3	Individual	100%	100%
Program 3	Pair	58%	116%

(Williams notes that timing for Program 4 not available, due to troubles with data entry)

For each assignment, pairs spent less elapsed time than individuals
Some initial adjustment required
- First assignment required about 60% more overall time
- Pair programming requires adjustment from traditional, individual-oriented approach
- Must adjust to other person's habits, styles, ego
After initial adjustment, pair programming took about 15% more overall time
