"They loved the demo." That's not solutions design. Solutions design is a formal, documented endorsement from the buyer's technical team that your solution meets their evaluation criteria. Without it, you're guessing—and guessing doesn't close enterprise deals.
Most SE teams treat solutions design as something that happens organically. The prospect seems happy, the AE says the deal is progressing, and everyone assumes the technical evaluation is "done." Then procurement asks for another round of testing, a new stakeholder raises concerns, and the deal slips a quarter.
Solutions design needs to be an explicit, defined milestone in your sales process—not a feeling.
What Solutions Design Actually Is
Solutions design has three components:
- 1.Defined criteria. Before the evaluation begins, both sides agree on what "success" looks like. These are specific, measurable outcomes—not vague sentiments like "easy to use" or "meets our needs."
- 2.Demonstrated proof. During the evaluation, you systematically demonstrate that each criterion has been met. This could be through a POC, a guided evaluation, or a series of technical deep-dives.
- 3.Formal endorsement. At the end of the evaluation, the technical buying team explicitly confirms that the solution meets their criteria. This is a verbal or written statement, not an assumption.
If you can't point to the moment when solutions design was declared complete, you don't have one.
Defining Criteria Per Deal
Solutions design criteria aren't universal. They vary by deal, buyer persona, and use case. The SE's job during discovery is to uncover what matters most to this specific buyer and translate that into measurable evaluation criteria.
Good criteria share three characteristics:
- •Specific: "Process 10,000 records in under 5 minutes" vs. "fast performance"
- •Buyer-originated: The criteria should come from the buyer's priorities, not your product's strengths. Let them define what matters.
- •Mutually agreed: Both sides need to sign off on the criteria before the evaluation begins. No moving goalposts.
Aligning Solutions Design with Economic Buyer Priorities
Technical evaluators care about functionality, integration, and architecture. Economic buyers care about ROI, risk, and time to value. The best solutions design criteria bridge both perspectives.
For every technical criterion, ask: "How does this connect to what the economic buyer cares about?" If the criterion is "native integration with Salesforce," the economic buyer translation is "reduced implementation cost and faster time to value."
When you present the solutions design outcome to the broader buying committee, frame it in economic terms. "The technical team confirmed that our platform integrates natively with their existing stack, which means implementation can begin in two weeks instead of eight."
"They Liked the Demo" vs. "We Have Solutions Design Sign-Off"
Here's the difference in practice:
The difference isn't subtle. One is interpretation. The other is evidence.
Solutions Design Criteria Template
Use this framework for every enterprise deal:
For each criterion, document: the requirement, how it will be validated, who from the buyer's team will evaluate it, and what "pass" looks like.
Solutions design criteria aren't overhead—they're the mechanism that converts technical enthusiasm into commercial commitment. Define them early, track them rigorously, and close them formally.
