I came into this presentation about 20 minutes in because I ditched my first choice conference due to irrelevant content with respect to my likings. I'll get more into the details of my general feelings towards the Agile 2008 conference and its enormous amount of topics in a later post.
What left the biggest impression in my mind when I stepped in was the following quote which I used as the title of this post: "It's not an Iteration if you Only do it Once!"
I found this to be quite revealing because I sometimes find that we forget what iterative and incremental development is over time and slowly fall back into the dreaded waterfall model without even knowing it. Lets take a look at what gets us into this pattern and try to find some strategies to get out of it.
The following should sound familiar: "That iteration stuff is good but we have commitments to keep...". Software is often a line item in a larger plan. Failing to release on time may put the bigger plan at risk. In order to properly plan we need to properly estimate and with estimation comes uncertainty.
Jeff proposed 3 strategies themed with musical clips to help us cope with this uncertainty.
1. Follow the Money
- Follow the user stories back to their source
2. Don't choose your solution too early
- Firstly write user stories that describe what people want to do
- Defer selection of which user stories to implement to later
3. Build up feature quality iteration by iteration
I found this section to be VERY RELEVANT. The following is a heuristic for slicing up quality goals:
- Comfort, Luxury, Performance
- Iteration 1: You build and implement basic text editing capabilities such as creating a file, saving a file and editing text. (Necessity)
- Iteration 2: You provide a mechanism that allows basic style such as font selection, bold typeface and italic typeface. (Flexibility)
- Iteration 3: You implement unit testing beef up the code of the basic features to make it more robust. (Safety)
- Iteration 4: You add some bells and whistles to make the application's visual style appealing and optimize the memory required. (Luxury)
Finally, let me know if you need some clarifications on this information for I have miss a small part of this talk. I'll be glad to provide more information once I receive a copy of the presentation from Jeff.
