It ain’t Kanban if you don’t use WIP Limits

26 April, 2017 (20:07) | Uncategorized | By: seth

In my last post I discussed How WIP Limits work to help you get more stuff done. Some folks like to compare Kanban and Scrum, but this is not really an apples to apples comparison. Scrum is a framework with defined roles, activities and artifacts – It gives you a prescriptive formula for how to […]

How WIP Limits work to help you get more stuff done

An UPDATED version of this blog post is here: Two key practices in Kanban are Limit WIP Manage Flow (image from Lean Kanban, St Louis) “Limit WIP” means limit the work in process — for any given step in your workflow you limit how many items can be in that state. So a WIP […]

Using story Points for estimation – the big view

13 May, 2016 (13:56) | Uncategorized | By: seth

Most agile software teams choose to define User Stories as the increment of value they deliver, with a given release or product comprising multiple of these stories. To figure out what they can do and when, teams need to estimate these stories. Estimating, using time units such as days, person-days, or ideal-days is a big […]

Why inspect and adapt?

10 November, 2015 (14:46) | Uncategorized | By: seth

In a recent talk I gave on Scrum I highlighted the power of inspect and adapt cycles.  Or as the the Agile Principle puts it: Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. First I talked about a non-agile project that did NOT inspect and adapt.   On […]

Back to the Future Part 2 – Predictions, Hit or Miss

24 October, 2015 (20:57) | Uncategorized | By: seth

In honor of the recent Oct 21, 2105 “Back to the Future Day” I have started to re-watch the trilogy with my daughters.  It is their first time seeing it.  I guess I underestimated how difficult it might be for a 4 year old just starting to master the concepts of yesterday and tomorrow to […]

Working at Amazon

By now you have certainly heard of the NYT piece (or as I like to refer to it, the NYT hit piece) on working at Amazon.  And if you are truly interested, you may have read: Jeff Bezos’ response and some random employee’s response (that Jeff makes mention of) As a current Amazonian, I have […]

In this September 2012 blog post I posited on what the colors of the (then new) Microsoft logo represented The Four Colors of the New Microsoft Company Logo I was just riffing… I had no inside knowledge, and was leveraging what others before me had suggested.  Here in summary is what I said: Today for […]

Amazon and Testing in Productions: Some good, some bad

7 August, 2015 (08:52) | Uncategorized | By: seth

Amazon has a well deserved reputation of being data-driven in its decision making.  TiP is a vital part of this, but may not have always been approached as a legitimate methodology instead of an ad hoc approach.  An example of the latter can be seen by anyone on the production site who searches for […]

The pyramid and the dog-bone revisited

22 July, 2015 (12:54) | Uncategorized | By: seth

I previously talked about the dog-bone approach to testing, and how we testers love our shapes such as the Test Pyramid.  But I did not connect the pyramid to the dog-bone.  Now permit me to remedy that Pyramid This is the Test Pyramid introduced by Mike Cohn in 2009 In brief it says Unit Testing […]

Analysis and Design as named columns in Kanban? In Scrum?

17 July, 2015 (09:14) | Uncategorized | By: seth

I came across this Kanban board [it is this blog post, but the while the post is interesting, it actually does not at all address what I am about to talk about] What I found interesting was the Analysis and Design columns. Reflecting on this, this can work for Kanban because it is continuous flow […]
