Rapid Development : Function Point Analysis

November 19, 2015 by John No Comments »

Rapid Application DevelopmentWhen I was studying Computer Science, one of my favorite CS Professors was a fan of Steve McConnell’s approach to system analysis and software design. I had read his book Code Complete, which is an industry standard for software design. When I was getting ready to go on the road for a brief tour, my professor suggested I take McConnel’s Rapid Development as reading material.

Side note : I have always been a voracious reader when traveling, particularly on band tours. I would carry a few books with me at the start of any trip, and as I completed a book, I’d look for a bookstore where I could trade it for another title. In some cases, venues provided a “band house” for our lodging while performing several shows in the area. This was especially nice, because it meant we could (1) do our laundry and (2) actually cook a meal. The band houses usually had a small collection of videos and books to keep us entertained. I often would leave books behind for others to read. On occasion I found an interesting book and brought it along for the next leg of the journey. In Victoria, BC, the band house had a copy of Foucault’s Pendulum, by Umberto Eco, which I finished reading as we made our way down the west coast. Ultimately, that book was left in Bend, Oregon. I’m sure it continued its journey in the hands of another musician.

My copy of Rapid Development is from the first pressing. It’s a dog-eared book with post-it notes, and hand-written margin notes. It’s been on my work bookshelf in various cubicles and offices for the past 20 years, and I’ve loaned it out more times that I can count. This is the book that made me want to become a project manager. It also has been a book that I have found useful as a manager and leader.

Among the highly useful principles in this book is the practice of “Function Point Analysis”, which is an estimation technique that is very useful in modern Agile decomposition and estimation. I have adapted FPA for use with my PMO team at Disney, and it’s a good basis for task estimation in software development. In addition, the book emphasizes effective principles for managing high-performing teams, and for business customer satisfaction – which has a strong basis in effective, precise communication.

For Agile development teams, one of the initial opportunities for improvement tends to be estimation. Newly formed teams will not have a baseline velocity, and will not have estimation / retrospective data to feed the continuous improvement loop. Narrowing the estimation error has an immediate effect on normalizing the team’s performance; this is where FPA can be effectively leveraged. After 4-6 sprints, estimation variability versus actuals will be reduced, and sprint loading will become a reliable predictor of the work that will be actually accomplished in each sprint.

This book is worth a read. Steve’s seminars are also interesting, and he has established a good curriculum for technology thought leaders.

 

Thoughts on the Dudley Manlove Quartet Halloween Performance 10/31/2015

November 2, 2015 by John No Comments »

JH Halloween 2015Every year, the Dudley Manlove Quartet performs a big Halloween show. During one of the sets, we pay tribute to another band by dressing up as them and performing several of their songs. This year’s honored artist was Elvis Costello. He has written so many fantastic songs that it was difficult to select our favorites. I wrote out charts for the following songs, which was mostly a straight-forward process.

  • Alison
  • Every Day I Write The Book
  • I Can’t Stand Up For Falling Down
  • Oliver’s Army
  • Pump It Up
  • Radio Radio
  • (What’s So Funny) ‘Bout Peace, Love, and Understanding?

The most difficult transcription was Alison, owing to the gorgeous jazzy style of John McFee’s guitar work. There are always plenty of online tablature transcriptions for popular songs, but they’re often incomplete or incorrect. It’s faster for me to just write it from scratch, and that also helps me internalize the part. It took me a few revisions to get this one sufficiently correct.

The performance was a blast. Our audience brings a lot of Halloween spirit, and really dresses up. There were some fantastic, funny costumes. The show was sold out, which always happens on Halloween. We arrived to the club in the midst of a massive rain storm, which made for a wet load-in. Once we got through with our soundcheck, the rain had let up, and we all walked to a local restaurant for dinner together. Upon our return, the room was full and abuzz. We played two long sets, and dug into some back catalog material. Definitely a good night.

For this show I decided to use my Xitone guitar monitor rather than the EA VL110 cabinets. The Xitone has a great, immediate sound, and having my guitar coming from directly in front of me is nice. The AxeFX rig sounds amazing every time, and I love getting compliments from the FOH engineers about my guitar tone. At the end of the night, we prepared to load out – and discovered the massive rain storm was back! I parked directly in front of the club to make load-out as quick as possible, and still was completely drenched in the three minutes it took to load the car. Good thing my cases are waterproof!

Our next public show is New Year’s Eve at the Triple Door. I’m certain it’ll be another wonderful night.
