How to decide on analysis elaboration approach
This methodology has
shown three different ways in elaborating the scenarios identified in the
inception phase. Which approach is right for your organisation?
tend to have a large scope and are often characterised by poor initial
scoping. Such projects are often fraught with issues internal politics and
overlapping roles within the company structure, issues that could be avoided
if scope is very clearly defined. If the project is a
multi-million pound project that will span several years then the extra effort
associated with hybrid approach will be worth it.
If the management of component delivery is likely
to be an issue – for example if likely to be outsourced, or if components have
a danger of having overlapping boundaries, then a component level approach
should be considered.
If the scope of the enterprise is small, or the
architecture is simple an approach with a greater emphasis on analysis class
modelling will be more useful.
The following table summarises the key
differences and advantages/disadvantages of how scenarios can be elaborated.
Whilst either will bring real benefits to scoping and project stability, there
will be situation where one may be more suitable than the other.
