A multi-node collaboration network can include multiple computing nodes communicatively coupled to a collaboration server. A computing node can be joined to the multi-node collaboration network for sharing data corresponding to a current project among a set of project team members. Current project data can be compared, using computer hardware, with previous project data stored in a data storage device communicatively coupled to the collaboration network. A previous project corresponding to the current project can be determined, using the computer hardware, based on the comparing the current project data with the previous project data. Using the computer hardware and responsive to detecting a nonconforming decision, an electronic notification of the nonconforming decision is provided.
