PiWars Postponed, New Plan…

By | 14/03/2020

With a heavy heart, PiWars has been postponed and a Virtual PiWars has been announced for April 25th prior to a full competition being run. This is very much the right thing to do and I totally support it. One thing this does mean is more time to overcomplicate expand functionality! Here are a few things I’ve been thinking about that I’m going to investigate further.

I’ll start running through these in order, based on the MoSCoW priority system. It’s a simple way of prioritising tasks.

This page is going to be updated each time a task is done with relevant links added to blog posts or videos.

To MoSCoW!

Must have, Should have, Could have, Won’t have. A logical follow up to my previous post on the MVP of MFP.
