Why did I need lean?

I’m going to try lean
Before I learned about
lean, I knew I wanted
to focus on user
stories instead of
features
But I already have an idea/solution

But, I can’t get my mind off solutions

have in mind should be
renamed to my “first

“How do I identify a
problem worth
solving?
What do I ask?”
I broadly asked
“What are your top
problems with
caregiving your mom?”
While focusing on the
ones I could solve
But also
“How are you
solving them
today?”
and
“And what does it cost
you to solve them?”
Now
“How do I find
interviewees?”
5 friends (don’t interview)

5 friends of friends
= 25 folks
Step by step interview process
Broad Problem interview summary
“What are your top problems with caregiving for your mom?”
Narrow Problem interview summary
“What are your top problems with your mom’s ADLs?”
Admittedly, I also interviewed the “solution”
during the problem interview
How I did the solution interview:
Watch them use your solution!

Layman's Guide to Lean Methodology

  1. 1. Layman’s guide to doing Lean Chirag Patel Co-founder | Chicago Health 2.0 | @CHIHealthTech Dir of Software Dev | ContextMedia | @ContextMediaInc chirag@chicagohealthtech.org @patelc75
  2. 2. How many of you are doing lean? How many of you want to do lean but too busy? Who is early stage and how early stage are you?
  3. 3. “Get out of the building” - every Lean evangelist known to man (easier said than done)
  4. 4. Why did I need lean? I built this interface that was rarely used
  5. 5. Mobile version At home version Next product: Lean1st product: Not Lean I’m going to try lean
  6. 6. Before I learned about lean, I knew I wanted to focus on user stories instead of features
  7. 7. But I already have an idea/solution
  8. 8. Our “non-lean” schedule from our 1st product Build demo with features based on assumptions Month 8Start Month 4 Feedback Build slightly better demo Make assump- tions Often wasted time & money Expensive Non- Lean Needed to fix this
  9. 9. Stage 1: Problem/Solution Fit Key Questions: Do I have a problem worth solving? Does anyone care about my solution? Are they willing to pay? my “lean experiment” focuses here Stages of product lifecycle
  10. 10. …. and focused on the “Problem” box in the business model canvas
  11. 11. “Who do I think are my early evangelists?”
  12. 12. Proactive senior Early evangelists as a experiment to figure largest addressable m Declining Senior I started by drawing my customer/user segment hypotheses and looking for early evangelist Post Discharge Senior Declining independently living senior with busy caregiver daughter
  13. 13. “It is better to be wrong than vague. If you are wrong, you iterate; if you are vague, you have wasted your time and cannot draw any conclusions.” Cooper, Brant; Vlaskovits, Patrick; Blank, Steven (2010-10-15). The Entrepreneur's Guide to Customer Development: A cheat sheet to The Four Steps to the Epiphany (p. 74). Cooper- Vlaskovits. Kindle Edition.
  14. 14. I started with what I thought were my top problems aka my hypotheses ….but decoupled the problem and solution
  15. 15. But, I can’t get my mind off solutions
  16. 16. and really wanna build my idea
  17. 17. But gotta stay focused on validating the problem
  18. 18. This solution/product I already have in mind should be renamed to my “first hypothesis”. After hypothesis, problem interview and then solution interview Source: “Running Lean”
  19. 19. “How do I identify a problem worth solving? What do I ask?”
  20. 20. I broadly asked “What are your top problems with caregiving your mom?” While focusing on the ones I could solve
  21. 21. But also “How are you solving them today?” and “And what does it cost you to solve them?”
  22. 22. Now “How do I find interviewees?” 5 friends (don’t interview) X 5 friends of friends = 25 folks
  23. 23. Step by step interview process
  24. 24. Broad Problem interview summary “What are your top problems with caregiving for your mom?”
  25. 25. Narrow Problem interview summary “What are your top problems with your mom’s ADLs?”
  26. 26. Admittedly, I also interviewed the “solution” during the problem interview
  27. 27. How I did the solution interview: Watch them use your solution! 1. Paint a picture 2. Don’t say anything about the solution 3. Prep them to “talk out loud” 4. Practice talking out loud on another product/site
  28. 28. Track Everywhere Mom goes A single hypothesis came from a resonating problem (told during interviews without asking) Don’t know when Mom went to the doctor → HYPOTHESIS STICKY
  29. 29. Declining elderly seniors Then created my early evangelist “persona card” (eldest daughter caregiver)
  30. 30. MVT1: Omnigraffle mockup MVT2: Unbounce Landing page MVT3: Clickable InvisionApp Mockups MVP1: RhoMobile cross- platform app (started concurrently with MVP2) I thought of them as MVTs (Minimum Viable Tests) instead of MVPs.
  31. 31. I did a mockup of a landing page as my MVT1 (using Omnigraffle)
  32. 32. Example learnings from iterating: • Voice recorder feature idea I put the Omnigraffle mockup MVP1 in front of people!
  33. 33. Declining elderly seniors Here’s my deployable landing page in Unbounce page, good enough! Unbounce has weight feature so you can easily do A/B experiments
  34. 34. To be charge or not to be charge?
  35. 35. All the while, I was interviewing all our stakeholders, not just the end users
  36. 36. We had our fair share of health tech complexities but we didn’t make excuses Sales Cycle
  37. 37. And learned a simple message to the stakeholders was absolutely essential for our sales cycle “Like Philips but automatic”
  38. 38. And we lived happily ever after
  39. 39. For me, lean is validating learnings on both the problem and solution before spending time and money unnecessarily So how did lean help me?
  40. 40. It’s not about saving time (or shitty MVPs) Build demo with features based on assumptions Problem Interviews Lo-fi Mock -ups Month 8Start Month 4 MVP demo app or clickable mockup Solu- tion Inter- views Interviews + Metric tracking Feedback Hi-fi Mock -ups Build slightly better demo Solu- tion Inter- views Make assump- tions Often wasted time & money Scalable Product Expensive Much cheaper Non- Lean Lean Even longer in healthcare
  41. 41. Solve “empathy” and “stickiness early!
  42. 42. “The Lean Startup” had great stories, but not actionable
  43. 43. • Actionable • Jumped around these books and skipped sections • Consumed in small chunks “I don’t know where to start” Started with these books!
  44. 44. Every week, I met with another (trusted) startup also doing lean I started meeting advisors early. Don’t wait for the “right time”
  45. 45. Problem interview MVPs & Solution Interviews Landing Page launch Surveys, focus groups, etc Best practice Research Shadowing/Inquiry Everything else (dev, biz, sales, fundraising, tech ops, etc) My approach is a subset of a larger holistic approach
