Perl

Role up! Role up! (but keep hold of your Moose and make your meta immutable)

What developers can do when the work-in-progress limit is reached

Introducing work-in-progress limits

In January this year, we (the NET-A-PORTER GROUP Product Management team) introduced work-in-progress limits to our software development process.

We added the work-in-progress limits as part of a Kanban-inspired move away from a fixed-iteration process to a continuous flow of work.

Exploratory testing is an approach to testing. Traditionally, testing has always had a “scripted” approach, where tests are planned based on a list of requirements supplied by the business stakeholders, and these scripted tests are written long before any software is even written. Although this might be useful in some circumstances, and scripted tests are still used in some circumstances within Net-A-Porter (in the regression team for example), it can be painful to use a scripted testing approach in other situations (like when testing new functionality in the streams).
