Why do we need Model Driven Development ... ?
System software projects fail to deliver on project goals ... why?
- No system software architecture
> System software architecture based upon inconsistent, incoherent documents :
Document based architectures emphasize controlling documents: which must be valid, complete, consistant, and must ensure that the implemention complies with all relevant document requirements e.g.
> operations document: defines how the system will satisfy the project objectives> functional analysis: will decompose functions and allocate to components, processes, etc.> diagrams/views:> requirements specification documents:> traceability documents: maps requirements to architecture/design decisionsThe document based approach to architecture provides a potentially rigourous method, but is difficult to maintain and enforce. It may well prove to be inconsistant and un-synchronized as it is dispersed across several (and more likely numerous) documents. Isolating and understanding a particular aspect of an architecture, a modification impact, or a traceability analysis can be laborious and error prone. This often results in inadequate (or no) synchronization between project components; resulting in the various stakeholder groups not being serviced with the information they need, and hence validation and verification of the system design becomes ineffective.
