Co-Created Business Cases: The Power of the IKEA Effect in B2B Sales
Why You Should Involve Your Champion in Building the Business Case
You've identified an enthusiastic champion inside the client's organization? Great! You've conducted a thorough discovery and you're ready to document the value of your solution in a compelling business case? Even better. But here comes the critical point: how do you ensure that business case doesn't end up as a beautiful document in a drawer (or worse, gets challenged internally), but instead becomes the tool your champion will actively use to "sell" the project to the final decision-makers?
The answer, counterintuitive for many salespeople accustomed to delivering "turnkey" solutions, lies in a powerful psychological principle: the IKEA Effect. Just as we value a piece of furniture we assembled ourselves more highly (even if it's imperfect), we're far more likely to defend and promote an idea or project we actively helped create.
In this article, we'll explore how to strategically apply B2B business case co-creation, transforming your champion from a passive recipient into a co-author and passionate advocate of your value proposition. We'll cover practical techniques, supported by artificial intelligence, to make this collaborative process both effective and efficient.
The Problem with "Beautiful but Useless" Business Cases
How many times have we spent hours building detailed business cases, packed with data and impressive ROI projections, only to send them to our internal contact and... hear silence? Or worse, discover the document was met with skepticism or even challenged by other stakeholders?
This happens frequently because, even when technically flawless, the business case is perceived as:
- Imposed from above: a vendor document, not a client tool.
- Generic: it doesn't fully reflect the nuances, priorities, and specific language of the client organization.
- Lacking ownership: the champion doesn't feel invested in defending it because they didn't actively participate in its creation.
As I explain in Chapter 9 of my book "B2B Sales in the AI Era: From Theory to Practice", a business case, to be truly effective in guiding complex decisions, must not only present value — it must generate consensus and internal ownership. And the best way to achieve that is through co-creation.
The IKEA Effect Applied to B2B Sales
The IKEA Effect, studied by behavioral psychologists like Dan Ariely, demonstrates that we tend to assign disproportionately high value to things we helped create through our own effort. This applies to ideas and projects as well.
When we actively involve our champion in defining and drafting the business case:
- We increase their sense of ownership: it's no longer "your" business case, but "ours." They'll feel personally responsible for its success.
- We boost their commitment: they'll be more motivated to dedicate time, share valuable internal information, and overcome obstacles.
- We strengthen their ability to defend it: by deeply understanding the logic and data (because they helped define them), they'll be far more effective presenting and defending it to colleagues and executives.
- We improve quality and relevance: their contribution ensures the business case aligns with the real priorities, language, and internal political dynamics of the client organization.
In practice, we transform the champion from a passive spectator into an active protagonist, exponentially multiplying the chances that the business case will not only be read, but adopted and used to drive the decision.
Practical Techniques for B2B Business Case Co-Creation
How does this principle translate into practice? Simply asking for generic "feedback" isn't enough. You need a structured process that invites and facilitates active collaboration. Here are some techniques I've battle-tested (many of which are explored in depth in Chapter 15 of "B2B Sales Strategies and Techniques Oriented to Client Results" on champion cultivation):
- Share an intentionally incomplete initial draft: never present a finished "take-it-or-leave-it" document. Send a first draft (perhaps a One-Page Business Case as described in the book) that's deliberately rough, highlighting areas where their contribution is essential. Use phrases like: "I've started sketching out a framework, but I need your help to ground it in your specific reality."
- Insert targeted comments and questions: within the shared document (e.g., Google Docs), embed specific comments that guide the champion's contribution. Not a generic "What do you think?" but pointed questions: "Does this cost-of-problem estimate seem realistic for your plant?", "Which success metric would resonate most with your Operations Director?", "Are there other internal stakeholders we should include in the impact analysis?"
- Organize brief joint working sessions: don't limit yourself to exchanging feedback via email. Propose short sessions (even 30 minutes) to work together on specific sections of the business case. This reinforces collaboration and enables richer dialogue. Use screen sharing and collaborative editing tools.
- Explicitly acknowledge their inputs: when you integrate the champion's suggestions, do it visibly and recognize their value. Use phrases like: "Great point on metric X — I've integrated it as you suggested," "Thanks for clarifying process Y — the Decision section is much stronger now." Make them feel like an integral part of the result.
Use Co-Creation to Test Your Champion
The co-creation process isn't just a way to improve the business case — it's also a powerful tool for qualifying your champion. Their level of engagement, the quality of their contributions, their willingness to "put themselves out there" internally to obtain data or validations — all of this tells you a lot about their real commitment and actual influence.
A champion who gives superficial feedback or continually postpones working sessions may not be the "champion" you thought they were.
A champion who gets passionate, brings internal data, connects you with other colleagues, and defends your shared conclusions is a valuable ally you can truly count on.
AI as a Co-Creation Assistant (Not a Substitute)
Artificial intelligence can support the co-creation process, but it should never replace human interaction with the champion. You can use AI to:
- Structure the initial draft: ask AI to create a One-Page Business Case template based on the principles discussed in the book.
- Suggest targeted questions: get AI help formulating specific questions to embed as comments for the champion, based on the deal context.
- Rephrase/Synthesize: use AI to improve the clarity and impact of the text once inputs have been gathered.
But the act of co-creation — the dialogue, the exchange, the trust-building — remains profoundly human and is the true heart of the process.
Conclusion: Build Bridges, Not Just Documents
The business case is not just a document to deliver — it's a bridge between your solution and the client's success. And the strongest bridges are the ones built together.
Actively involving your champion in creating the business case, leveraging the IKEA Effect, allows you to:
- Create more relevant, credible, and effective documents.
- Transform the champion into a motivated and competent internal advocate.
- Test and strengthen the quality of the relationship and their commitment.
- Drastically increase the probability of getting final decision-maker buy-in.
So the next time you need to prepare a business case, resist the temptation to do it alone "behind closed doors." Open the doors to your champion. Invite them to co-create with you. It will be the best investment you can make to turn that proposal into a shared success.

Frequently Asked Questions About Business Case Co-Creation
How much longer does co-creating a business case take compared to doing it alone?
It may require slightly more calendar time overall, since you need to align with the champion's availability and plan review cycles. However, the actual working time might even be shorter, since the champion provides insights and data you'd otherwise have to hunt down yourself. Most importantly, the time "saved" afterward — thanks to a smoother internal approval process and fewer objections — more than repays the initial investment in collaboration.
What if my champion doesn't have time or interest in being so actively involved?
That's an important signal. It could indicate the project isn't truly a priority for them, they don't feel enough "ownership" of the problem, or their internal influence is limited. In this case, rather than forcing the issue, try to understand why the engagement is lacking. Maybe you need to work more on quantifying the pain and impact for them? Maybe you need to find an alternative or additional champion? Co-creation is also a test: if the champion won't "play," the deal's chances of success are probably low.
How do I handle conflicting feedback when I involve multiple people beyond the champion?
It's a delicate but manageable situation. First, clarify roles from the start: the champion is your primary co-author; other stakeholders provide inputs and validations on specific areas of their expertise. Organize separate sessions if needed. When conflicting feedback emerges, bring it back to the champion and work together to find a synthesis or mediation that accounts for different perspectives while remaining aligned with the strategic objective. The business case thus also becomes an internal alignment tool for the client.
