How To Score Problem Interviews During the Lean Startup Process
This article is written by Ben Yoskovitz, Co-Author of Lean Analytics
Problem Interviews are designed to collect qualitative data. Theyâre meant to indicate strongly (or not) that the problem(s) youâre looking to solve are worth pursuing. Theyâre hard to do well, and take lots of practice and discipline to master. If you do it right, youâre left with a ton of insight into your customersâ needs and thoughts.
Unfortunately, those reams and reams of notes are messy. Interpreting and sharing qualitative data is hard, and often subjective.
So we want to try and score them. Scoring interviews is designed to help you quantify your results, without getting overly scientific.
The challenge here is that you canât beat a forest of qualitative data into a carefully manicured lawn of quantitative data. Weâre not even going to try that. And weâre also not proposing that you go overboard with this method: if youâre not good at collecting and interpreting qualitative data, itâs going to be difficult to get very far at all (through the Lean process or through any startup.) But our hope is that this method helps coalesce things a bit more, giving you some clarity when analyzing the results of your efforts.
During the Problem Interviews, there are a few critical pieces of information that you should be collecting. Iâll go through those below and show you how to score them.
1. Did the interviewee successfully rank the problems you presented?
During a Problem Interview you should be presenting multiple problems to the intervieweeâletâs say 3 for the purposes of this postâand asking them to rank those problems in order of severity.
If they did so with a strong interest in the problems (irrespective of the ranking) thatâs a good sign. Score 10 points.
If they couldnât decide which problem was really painful, but they were still really interested in the problems, thatâs OK but youâd rather see more definitive clarity. Score 5 points.
If they struggled with this, or they spent more time talking about other problems they have, thatâs a bad sign. Score 0 points.
Itâs important to note that during the interview process, youâre very likely to discover different problems that interest interviewees. Thatâs the whole point of doing these interviews, after all. That will mean a poor score (for the problem you thought you were going to solve), but not a poor interview. You may end up discovering a problem worth solving that youâd never thought about, so stay open-minded throughout the process.
2. Is the interviewee actively trying to solve the problems, or have they done so in the past?
The more effort the interviewee has put into trying to solve the problems youâre discussing, the better.
If theyâre trying to solve the problem with Excel and fax machines, you may have just hit on the Holy Grail. Score 10 points.
If they spend a bit of time fixing the problem, but just consider it the price of doing their job, theyâre not trying to fix it. Score 5 points.
If they donât really spend time tackling the problem, and are okay with the status quo, itâs not a big problem. Score 0 points.
3. Was the interviewee engaged and focused throughout the interview?
Ideally your interviewees were completely engaged in the process; listening, talking (being animated is a good thing), leaning forward, and so on. After enough interviews youâll know the difference between someone thatâs focused and engaged, and someone that is not.
If they were hanging on your every word, finishing your sentences, and ignoring their smartphone, score 8 points.
If they were interested, but showed distraction or didnât contribute comments unless you actively solicited them, score 4 points.
If they tuned out, looked at their phone, cut the meeting short, or generally seemed entirely detachedâlike they were doing you a favor by meeting with youâscore 0 points.
4. Did the interviewee refer others to you for interviews?
Yes, without being asked =Â 4 points
Yes, when you asked them to = 2 points
At the end of every interview, you should be asking all of your subjects for others you should talk with. They have contacts within their market, and can give you more data points and potential customers. Thereâs a good chance the people they recommend are similar in demographics and share the same problems.
Perhaps more importantly at this stage, you want to see if theyâre willing to help out further by referring people in their network. Â This is a clear indicator that they donât feel sheepish about introducing you, and that they think youâll make them look smarter. If they found you annoying, they likely wonât suggest others you might speak with.
If they actively suggested people you should talk to without being asked, score 4 points.
If they suggested others at the end, in response to your question, score 2 points.
If they couldnât recommend people you should speak with, score 0 points (and ask yourself some hard questions about whether you can reach the market at scale.)
5. Did the interviewee offer to pay you immediately for the solution?
Yes, without being asked = 4 points
Yes, when asked = 2 points
Although having someone ask to pay or throw money at you is more likely during the Solution Interviews (when youâre actually walking through the solution with people), this is still a good âgut checkâ moment. And certainly itâs a bonus if people are reaching for their wallets.
If they offered to pay you for the product without being asked, and named a price, score 4 points.
If they offered to pay you for the product, score 2 points.
If they didnât offer to buy and use it, score 0 points.
A score of 25 or higher is a good score. Anything under is not. Try scoring all the interviews, and see how many have a good score. This is a decent indication of whether youâre onto something or not with the problems you want to solve. Then ask yourself what makes the good score interviews different from the bad score ones. Maybe youâve identified a market segment; maybe you have better results when you dress well; maybe you shouldnât do interviews in a coffee shop. Everything is an experiment you can learn from.
You can also sum up the rankings for the problems that you presented. If you presented three problems, which one had the most first place rankings? Thatâs where youâll want to dig in further and start proposing solutions (during Solution Interviews.)
The best-case scenario is very high interview scores within a subsection of interviewees where those interviewees all had the same (or very similar) rankings of the problems. That should give you more confidence that youâve found the right problem and the right market.
