We have seen many times that successful project delivery comes less from having all the bells and whistles and more from effectively executing key processes. In previous posts, we have presented a series of eight project management processes that greatly increase the chance of project success on small- to medium-sized projects when executed properly. We have also presented ways to achieve similar results for smaller or larger projects, with a lesser or greater degree of complexity, number of full-time team members, and duration. These results are possible through using a tiered approach to project management rigor.
