I do not have experience with industrial projects, however I have been on a surgical research team. While on this team we went over the DDP of the project, and covered all tasks required. While working on our project it was crucial to complete each task before moving onto the next. There were many steps in the project the first being the acquisition of human blood, then separation of the fluid, then testing, etc. Although I was never actually pressed for time as much as I am sure industrial projects are, I do not believe that it would be possible to have completed the project by skipping steps or just moving on. The only time a step could be skipped were if it was something so insignificant that no bad outcome could possibly be a result. Skipping stages is dangerous as it could result in a higher cost variance in the long term. Each stage of the project feeds into the next, and skipping one could cause a snowball effect of issues. This would eventually result in more resources being required to fix these issues, thus raising the overall cost of the project.
