How Do I Test a New B2B Proposition?

In the B2B world, a 'proposition' is more than just a list of features. It is a coherent argument for why a company should spend money, change its internal processes, and take a risk by hiring you. The problem is that most B2B companies draft these propositions in a boardroom, based on internal assumptions about what they *think* customers care about.

Testing a new B2B proposition is not about market research surveys; it is about sales discovery. If you cannot successfully open a conversation and get a prospect to acknowledge that your proposition solves a 'painful' problem, then no amount of branding will fix it.

The Proposition Testing Framework

Testing shouldn't be about being 'right'; it should be about being 'relevant'.

1. Defining the Ideal Customer Profile (ICP)

A proposition that works for a CEO of a £50m manufacturing firm will fail with the IT Director of a 20-person startup. Your test must be targeted. Choose 20 companies that fit your absolute 'bullseye' target and tailor your pitch to them.

2. The 'One-Page' Test

Summarise the proposition on one page. It should contain: The problem you solve, the impact of not solving it, your unique approach, and the proof. If you can't articulate this clearly on a single side of A4, you will never be able to teach a sales team to sell it.

3. Measuring the Response

Do not just count 'positive responses'. Count the *types* of responses:

• The 'No' (Polite): 'Not the right time.' - This is common and manageable.
• The 'No' (Hard): 'We already have a solution.' - Your proposition failed to differentiate.
• The 'Yes' (Warm): 'Can you tell me more?' - The proposition is strong enough to start a dialogue.
• The 'Yes' (Hot): 'We have this exact problem, when can you meet?' - Your proposition is a winner.

Commercial Reasoning

A failed proposition is an expensive error.

• Revenue: Does this proposition lead to larger deal sizes or just more 'cheap' deals?
• Margin: Does the market value this enough to pay a premium, or is it a race to the bottom?
• Cash: How much time are you investing in the sales cycle?
• Capacity: Does this require your sales team to learn new skills, or can they sell it alongside the core?
• Complexity: Does this create a conflict with your other products?
• Risk: Could this proposition undermine your established reputation for 'high-end' quality?

When NOT to Test

Avoid testing if:

• You are trying to test a complex service with an email subject line. Some propositions require a 'human' bridge.
• You don't have enough prospects in your ICP. If your list is too small, you'll burn through it and learn nothing.
• You're testing during a holiday season where your ICP is out of office.
• You're not prepared to change the proposition based on the feedback.

The Goal of Testing

The goal is to move from 'I think this works' to 'I know this works'. When you find the version of the pitch that consistently gets you a meeting, you have a foundation you can scale. Then, you can bring in the full sales team, the marketing automation, and the long-term investment.
