Answer: I believe the best option to be letter a) an amount, benchmark, or degree set to define and measure progress toward a goal.
Step-by-step explanation:
Even though "communication" is a crucial word when it comes to using KPI, letter b does not offer us a good definition of it.
KPI means Key Performance Indicators and they must be chosen and specified according to critical or core business objectives. So, the following aspects are decisive when setting KPI's:
- what outcome is expected
- why such an outcome is important
- how it is going to be measured
- how the outcome can be influenced
- who is responsible for the outcome
- how to know when the outcome has been achieved
- how will progress toward the outcome be reviewed
An example of outcome would be increasing sales revenue in 15% this year. From that outcome, the other guidelines may be defined - business will become more profitable, the Chief Sales Officer is responsible etc.
KPI's demand thorough communication with the team and constant updating.
