About this blog

How To Be A Good Product Manager was a blog that provided resources and tips on good product management practices. While it focuses more on managing technical and online products, most of the concepts are appropriate for broader product management purposes.

  • All of the posts here were written by me, Jeff Lash — currently VP, Global Product Management at Forrester and previously (among other things) the head of product management research and advisory at SiriusDecisions (since acquired by Forrester).
     
  • For nearly 6 years (December 2006 – July 2012), I posted nearly unique 200 tips on all aspects of product management.
     
  • From September 2012 – February 2021, my posts instead were recaps of product management posts I wrote for the SiriusDecisions (and later Forrester) blog, information on other product management presentations I was doing, and various product management tips.

More About How To Be A Good Product Manager

The views and opinions expressed on this site are strictly mine and are not to be representative of my current employer or any of my past employers.

For my “original” Good/Bad Product Manager posts starting in 2026, in most cases I came up with ideas for the postings based on a “good” product management experience, and then I tried to think of the exact opposite approach that would be a “bad” thing to do. Other times they are based on examples, case studies, or others’ experiences. “Bad” examples should not be interpreted to be based on product managers I have worked with in the past or with whom I am currently working. (Hopefully, though, they are not representative of product managers I will work with in the future!)

From 2008-2012, I also ran Ask a Good Product Manager (no longer online), which provided real answers to your real product management questions.
