11. Your answer should look something like the following sequence. Check for any steps or
details you missed in your answer.
a. Look on the table next to the bed. You will see an odd plastic box with a coiled cord
looped on one side. This is a “telephone.�?
b. Looped cord is connected to a bracket-shaped piece on the top of the telephone.
The brackets end in two round cups. This is the “receiver.�?
c. Pick up the receiver and notice that one cup has many more holes than the other. Put
the cup with the fewest number of holes to your ear. You should hear a loud, steady hum.
d. Push the numbered buttons in the following order: 5-5-5-1-2-3-4. When you hear a
voice answer, begin talking.
1. The original two testers, B and Z, were progressing at a steady rate which was not quite
enough to keep up with the goal. Tester D was added in January but the team's total output
was not improved. This could be due to effort diverted from testing to provide support to
D or to verify his tests were done properly. On January 8, C and K were thrown into the
mix while B took a day off. We can presume C and K knew what they were doing as the
group output went up and they almost caught up with the goal line. K and Z did not par-
ticipate after that and the output went back down even as B returned. Ultimately only D
was left on the project as presumably the others were reassigned to more vital testing. D
completed seven tests on the 12 th but it remains to be seen if he can sustain this output and
hold the fort until this project can get its testing staff back up to where it should be. The
two important observations here are that you can't treat every tester as an identical plug-in
replacement for any other tester—they each have their own strengths and skill sets—and
adding more testers does not guarantee a proportional increase in team output, especially
during the first few days.
2. Test execution is currently 22 tests behind the goal. In ten working days, the team needs to
complete 10 * 12 tests to match the planned rate, plus the 22 tests needed to catch up. This
means 142 tests in ten days. Strictly going by the average rate of about four tests per day
provided in Figure 9.3, three testers would only complete 120 tests in that time, but four
testers could complete 160 (4 testers * 4 tests/day * 10 days). There is currently one tester,
so three more need to be added. In a situation like this, it's good to staff a little above
what's needed to account for startup and learning curve time. The extra 18 staff days
between the need (142) and the projection (160) will come in handy.
3. Tester C made the best use of her test opportunity to find the most defects per test.
However, other testers such as B and Z were able to perform many more tests and find a
few more defects. Since “Best Tester�? is based on the combined overall contribution to tests
completed and defects found, C is not in the running. It's still important to identify C's
achievements and recognize them. If B and Z could have been as “effective�? as C, they
could have found about six more defects each; a very significant amount.
