The document discusses three chapters from an unknown work: Chapter 27 discusses unreliable data, noting that test equipment may be less reliable than the devices being tested. Measurements taken with unreliable tools may not accurately represent the properties of what is being measured. Chapter 29 states that the tools used to measure impact what is achieved. If measurements reward certain behaviors, people and organizations will adapt to those metrics. Chapter 30 encourages pursuing significant goals and problems. Preparation and continued effort are important to making important contributions, and having confidence despite uncertainties. The chapter questions whether all efforts are truly worth it, citing Socrates that an unexamined life is not worth living.

2. Chapter 27 – Unreliable Data
• Is your data as accurate as advertised?
• How do you propose to test a device;
• less reliable test equipment
• very limited time to test
• device is to have a very long lifetime in the field

3. Chapter 27 – Unreliable Data
• Why I should believe the data was consistent?
• Hamming’s rule:
• 90% of the time the next independent measurement will fall outside the
previous 90% confidence limits!
• Averages are meaningful for homogenous groups but for
diverse groups are often meaningless.

4. Chapter 29 – You Get What You Measure
• Choose your measurement tools carefully
• The way you choose to measure things controls to a large
extent what happens.
• In organizations diversity matters however mostly the
recruiters chooses the persons like themselves.
• In army we train people in war games to use an idealized
fleet and not the real one! It is same in business games.

5. Chapter 29 – You Get What You Measure
• In organizations each person is bending things so they
themselves will look good!
• If the whole organization is working together to fool the
top, there is little the top can do about it.!
• In computing, the programming effort is often measured
by the number of lines of code, what!?
• You get what you measure

6. Chapter 30 – You and Your Research
• It seems to me it is better to do significant things than to
just get along through life to its end.

8. Chapter 30 – You and Your Research
• Confidence in yourself, then, is an essential property.
• The courage to continue is essential.
• Intellectual investment is like compound interest,
• the more you do the more you learn how to do, so
• the more you can do.

9. Chapter 30 – You and Your Research
• Great people tolerate ambiguity,
• they can both believe and disbelieve at the same time.
• You should do your job in such a fashion others can build
top of it.
• Adopt
• Adapt
• Extend
• Elaborate
• But is it worth for all that effort?
• Socrates; 'The unexamined life is not worth living.'
