Procurement Models

Understand and communicate complex topics with the NLPA’s procurement models

Without procurement models, some concepts can seem too complicated, too confusing, too esoteric and even too boring. So, using procurement models can help you focus on your objectives, communicate your strategies more effectively, and simply succeed in areas you once thought too complicated!

The Next Level Purchasing Association and its founder – Charles Dominick, SPSM, SPSM2, SPSM3 – have created a number of legendary procurement models throughout the years to help guide your efforts. Here is a chronological list of those models with links to additional explanations.
