Which is NOT characteristic of a lean approach to work:

• Relentless attention to detail
• Commitment to data-driven experimentation
• Process driven by workers with little management involvement
• Charging workers with the ongoing task of increasing efficiency and eliminating waste in their jobs.

Which is true about tacit knowledge:

• Can be eliminated from most knowledge jobs.
• Is the knowledge locked inside the worker's head.
• Must be 100% codified in written form.
• Is often unreliable and not validated.

Statts and Upton (2011) studied knowledge projects that were pursued using a lean approach, they reported:

• Lean approach projects yielded higher quality results (fewer defects and mistakes), superior results in project time, and superior results in project cost
• Lean approach projects yielded lower quality results (more defects and mistakes), superior results in project time, and superior results in project cost.
• Lean approach projects yielded lower quality results (more defects and mistakes), poorer results in project time, and superior results in project cost.
• Lean approach projects yielded the same quality results (the same quantity of defects and mistakes), superior results in project time, and superior results in project cost.

The authors point out six guidelines to make knowledge work lean, please fill in the missing words (4 of 6 correct answers will earn you the full point):

• Continuously root out all _____________________.
• Strive to make _______________ knowledge  ____________.
• Specify how workers should ______________________.
• Use the __________________ method to solve problems quickly.
• Recognize that a lean system is a _____________________.
• Have ____________________ blaze the trail.

There are seven wastes identified in the Toyota Lean system, provide four: 

The "Five Whys":

• Are used to make waste visible
• Are used to examine whether accepted procedures are the best way to process work, based on the assumption that the current approach to a process is wrong.
• Is a process of continually asking questions until the root cause of every activity is identified.
• All of the above

When problems are encountered, who should fix the problem:

• Impartial, outside experts
• Management
• The individuals who made the mistake
• A skilled team of workers from outside the immediate department
