Title: Validation risks of using development methodologies in a hierarchical fashion – When contracts meet architecture ownership.
Abstract: Design methodologies that are based on decomposition concepts are often perceived and used hierarchically. However, the validity of such use is not trivial, especially with regards validation activities. Enforcement of such methodologies at different levels of the system decomposition, blended with contractual obligations, often result in vanished responsibilities on validation activities, which threatens design validity and consequently integration success. This talk revisits the concept of validation from the perspectives of requirements ownership and contractual obligations. By clearly identifying who holds responsibility on validation activities by ‘methodology’ instead of merely by ‘contract’ risks related to system integration can be reduced.
