S2 Ep36 Custom order or line extension? Who makes the call
A key account asks for a new format of a product you already sell, and the gate review takes twenty minutes because everything about it feels decided. Months later, the launch has answered one account's question and missed the jobs the wider market was hiring the product to do. Who this is for: product managers, product leads and product marketers at life science tools companies who own line extensions and gate decisions. Dr Matt Wilkinson and Dr Jasmine Gruia-Gray start from a bioRxiv study on how researchers choose antibodies, where trust sits in the lab's own track record with a product. Jasmine then explains the two sentences a line extension needs before the gate review, a problem statement and a goal statement. They close on who decides when a custom order graduates into a line extension, and what to do with three weeks until the review. Key idea: The product manager owns the call. A second unrelated request, or the urge to tell customers who haven't asked, turns a custom order into a line extension, and the problem statement has to prove the loss is shared. What you will learn:- How a problem statement separates a custom order from a line extension- The two triggers that force the graduation call, and why the first one lags- Why the customer's current workaround is the best signal of how many labs share the problem- How to test a goal statement with the spec sheet test and the jobs-to-be-done question- A three-week plan for a key account request before the gate review- How to write the problem statement when sales has already promised the deal Chapters:[00:00] Introductions[00:27] What a bioRxiv antibody study says about trust[03:19] The two sentences the gate review skips[05:24] Custom order or line extension[07:38] Writing a goal statement the customer can check[09:58] Stage-Gate and the case for a lighter process[12:36] Who makes the call[14:57] Three weeks to the gate review[17:37] When sales has already promised the deal[19:05] Closing Keywords: line extension, custom order, problem statement, goal statement, product requirements document, Stage-Gate review, key account request, portfolio management, product management, antibody selection, voice of customer, life science marketing podcast Watch the full conversation and subscribe for new episodes of A Splice of Life Science Marketing.
