According to wikipedia on customer value proposition:
A value-proposition should contain at least five elements:
- current situation (including problems, causes and effects)
- target situation
- when to reach the target situation
- cost of reaching the target situation and opportunity cost analysis
- the benefits of both the targeting and the achievement phases
Since the candidate is offering a complete proposition to an employer they should be able to indicate an awareness of timing. For example, the employer might want to know what they can do to deal with possible short-term backlogs or the absence of a long-term plan. The candidate must also show how previous results and skills will take the employer from their current situation to the target situation.
Having written this, just remember : Don't be downhearted. There are lots of good résumés and lots of bad ones. Many that are good don't get jobs, many that are bad do.
