The disadvantages would be lack of focus, poor integration, being slow, that is, the project takes a longer time and lack of ownership of the project.
The dedicated team approach has weaknesses and strength with the strength being simple, fast, cohesive and cross-functional integration. The weaknesses are, it is expensive, there are internal strife, limited technological expertise and difficult post-projection transition
The matrix team on the other hand has advantages such as being efficient, strong project focus, easier post-project transition and being flexible. The disadvantages for this functional unit are dysfunctional conflict, infighting, quite stressful and again another slow process.
