A drawing diagram for the Simple Multi- Attribute Techniques (Smart)

including the The client rank the value adding attributes in order of their importance in

achieving project objectives.

Under the SMART value tree the weighting for each of the values is expressed as a decimal of less than 1, such that for any level of abstraction for any single attribute, the total weighting adds to 1.

By attributing costs to the value tree it is possible to assess the cost of undertaking a function relative to its importance in the overall project, and to consider different approaches to undertaking the same function for fewer resources.
