If three people have 1/3rd of the knowledge needed to solve the problem (for example, a front end designer, a back-end designer from team 1, and a back-end designer from team 2), the total time expended is shorter if the three people research their part for 2 hours and then get together for an hour than one person writing based on faulty assumptions and having to go back to the drawing board anyway. The larger the organization, the less one person can hold the entirety of the solution in their head.
