Fast incremental delivery of application improvements is often incompatible with traditional departmental silos
DevOps is all about fast incremental application improvements. Businesses are discovering that they prosper more with this approach than the traditional, slower, all-at-once approach because it delivers value sooner. This saves and makes the business money. Traditional development is built around departmental silos, Development, QA and Operations. Each silo has different, sometimes conflicting priorities.

DevOps emphasizes collaboration amongst people from different teams. It is important therefore that tools can be easily used by different groups on a project by project basis. Tools must also fair well with short development cycles and have superior testing abilities which enable production ready code and mature deployment capabilities. A solution is to identify the main bottlenecks hampering the DevOps strategy and choose tools which help eliminate these to get the greatest and fastest payback.
