MIT Sloan Management Review published an interview of Clayton Christensen — one of the last if not the last before he passed away. He was a huge influence on how I (and many) think. Here are a few interesting quotes (in italics) from the piece, with color commentary below each one: “Disruptive innovations are not breakthrough innovations or “ambitious upstarts” …

Interviewing Designers and PMs: The Design Challenge

Giff Constabledesign, management, product management

It’s really hard to interview product designers and product managers. The most effective step I added to my cycles several years ago is a design challenge. The challenges themselves are a 2-hour take-home challenge, and then a 1-hour presentation with cross-functional members of the team. Because of the time commitment, it is best saved for late in the interview cycle. …

Alex Danco publishes an excellent newsletter Two Truths and a Take and today’s thought provoking essay is all about the limitations of having hypotheses: they can close our minds off to creativity and discovery. Danco writes, “when we analyze the results of an experiment, our mental focus on a specific hypothesis can prevent us from exploring other aspects of the …

Should you make some or all of your roadmap public? If yes, then what are some of the considerations? I had to answer this question recently.

Like many of you, I’m constantly playing with how to run and scale effective communication across multiple product managers, cross-functional teams, and a broader organization.

This post roughly mirrors a talk I gave about a month ago to two product manager communities (Product School and Product Faculty). If you prefer watching video, a recording of one of the talks is here. Roadmaps are an important and necessary part of the product manager job.

Do we really need PMs?

Giff Constableproduct management

I gave a talk on roadmapping recently to a large group of product managers, and one asked the question: “Do companies really need product managers or is it just a facilitation role between the different other roles that can go away if they get better at collaboration?” It’s an understandable question, and one I’ve heard for years. Indeed, modern product …

A New Book: First Principles Product Management

Giff Constableproduct management

I have this theory that product leaders can and should copy best practices, but you can’t copy someone else’s playbook. The job is way too context-specific.
