Every morning after the run around with a 2 year old I come into work and make a cup of tea and I‘ve had some ideas bubbling in my head about how I can apply this to lean principles.
Tea making is an activity that all of us partake in pretty often. Its a social activity as well as a great way to make friends (see Dan Ashbys blog Why tea is a great tool for a tester).
It got me thinking about the different ways I made tea, based on what criteria I set for it.
- Sometimes I want a cup of tea FAST. I have work to get on with (and blogs to write).
- Sometimes QUALITY is the most important. I am making tea for others. I want them to enjoy my tea and commend me on my tea making skills.
- Sometimes the SCOPE of tea making might increase. I might have a mini meeting with someone while making the tea.
For speed I want the fastest cup of tea, with no waiting for the kettle to boil so I can get back to my desk and start my day. My steps are:
- Fill kettle
- Put it on boil
- Wash cup (optional)
- Put tea bag in
- While kettle is boiling grab a glass of water and take it to my desk
- Back to kitchen and tea bag in cup
- Add the milk (controversial I know but for speed this is the key!)
- By the time the milk has finished the kettle has finished
- Pour the water into the cup
- Let it brew quickly then squeeze the bag a lot to get strong tea flavour.
- Take bag out and all done within 90 seconds I have a cup of tea.
Quality is a bit different:
- Brew time would be higher.
- Milk will go in last, which impacts speed.
- I might have a lot of cups to wash which will increase the time, also impacting speed.
- I wouldn’t be running around the office sorting my water out, I would have to do that later.
Scope is different too:
- If a discussion happens while I am making tea for myself, I will straight away increase the quality by brewing more. Speed isn’t too much a factor in this situation.
- No time here for water either, so it would happen later
Let me know about any other daily tasks you do that gets your brain bubbling like this.
Oops – almost forgot to drink my morning tea!
