BC (before children) I was a production manager for a pharmaceutical manufacturer and each month I needed to measure my WIP-work in progress. WIP cost's money and the more WIP you had the more money you were carrying and the more pressure you received from the financial controllers.
Thankfully I don't have to measure my WIP when it comes to my quilting projects and thankfully there are no financial controllers as I think I this venture would be non-viable as my WIP is huge.
However this is the year for getting my WIP (UFO's) reduced. This month I have made some serious progress.
