I agree with Adrian that processes are most important during collaboration. One company may utilize the waterfall method of managing projects while another may use agile. It should be up to the company organizing the collaboration to get each company to agree on a certain process. Standardization is also critical to ensure everything flows the same and everything is done the same regardless if one company thinks their process is better than the others. The point of collaboration is for everything to work together seamlessly to produce a quality product.
