Using spare time

5 March 2018 by Robert Falkowitz 1 Comment

lean-kanban task management goals

There is a strong contrast between the traditional management view of spare time and the kanban view. Traditional managers1 view spare time as something to avoid, as a sign of inefficiency or even laziness. One im­por­tant responsibility of such managers is to keep workers busy. In contrast to this, network queuing theory—and kanban in particular—show […]

When is a kanban tool not a kanban tool?

7 February 2018 by Robert Falkowitz

An indicator of the increasing popularity of kanban is the number of software tools and online services that claim kanban functionality. For those practitioners who have seen the tremendous benefits of kanban, this should be a gratifying development. But what does it really mean for a tool to support or to enable kanban? And what […]

Lean configuration management: a conundrum

2 June 2017 by Robert Falkowitz Leave a Comment

How does a purely internal activity like configuration ma­nage­ment add value to customers? Would a customer gladly pay you for your configuration ma­nage­ment ac­ti­vi­ties? Keeping your con­fi­gu­rations under control is hardly value adding in the same way as, for example, increasing the utility of a service. And yet, good configuration management under­pins virtually all service […]

On value streams, chains and life cycles

1 August 2015 by Robert Falkowitz

Value chains and value streams

There is confusion among the three concepts of a value chain, a life cycle and a value stream. We see this both in feedback on my recent article on a value stream for service management and in many other places. I believe it is useful to treat them as different concepts, so I will try […]

One of the main benefits of a lean/kanban approach to IT is the simplification of processes expressed in the value stream of each team.
