This whitepaper has covered a range of challenges associated with heterogeneous environments and explained why visibility for test management, plus all the other elements within the software development lifecycle, is essential. The whitepaper has also highlighted the importance of openness and transparency in terms of gaining an accurate view across the entire supply chain. Emphasis has been placed on the fact that organisations that are currently managing input from various sources across and outside the company must consolidate this disparate information into a central view accessible by all teams at all times.
