Blue Belt is where the tools come off the shelf and your work is inspected. White Belt taught you what the methodology is; Yellow Belt and Green Belt is where you apply it on a live account and a live deal, and where your sales process gets managed — by you and by your leader — against that application. You will build an account plan on a real account, capturing who is who, what they have bought, what they could buy, what actions you have taken, and what actions remain. You will build an opportunity plan on a live deal, including the opportunity assessment that forces you to define your differentiation. You will construct the ROI and business case for that deal, translating your solution into quantified business value the customer can defend internally. And you will apply MEDDPICC on that same deal, walking through each element with the discipline the program expects. You will also learn what it looks like when a sales process is managed well — how your plans and your qualification translate into the expected stage behaviors, the expected artifacts, and the expected conversations with your leader. Yellow Belt is the first belt where a gap between what you say and what you do becomes visible. Certification requires you to submit a real account plan, a real opportunity plan, a real business case, and a MEDDPICC-qualified opportunity for practical evaluation. You are not tested on your recall of the framework. You are tested on whether you used it.
