TABLE 1
2. (a) State why a ‘What if' analysis may not be appropriate for a risk analysis.
(b) Complete the following steps in a ‘what if ' analysis for the introduction of a ‘just in time'* form of production materials supply to a car production unit.
- Explanation of the Activity
- Area of interest
- Sub-systems.
(*‘Just in time' is a method of ordering and delivery of stock parts employed by a company, where the company has delivered on a regular, often daily, basis only enough parts for a short period of production. Thus capital that would otherwise be tied up in large stockpiles of production materials is released and cost of storage is avoided.)
(c) Complete TABLE 2 by the generation of:
- ‘What if' questions
- and solutions to potential problems.
