This video is unavailable. My phone starts ringing. Development (By-Donald G. Reinertsen). Product Development: Fast Feedback reduces loss from bad outcomes and enables exploitation of good outcomes, Focus control on project and process parameters with the highest economic influence – common sense, Control parameters that are both influential and efficient – again common sense, Select control variables that predict future system behavior — early interventions, Set tripwires at points of equal economic impact — don’t ignore the small parameters because if they go wonkers they can have an impact, Know when to purse of dynamic goal — our original goal is based on noisy assumptions, Exploit unplanned economic opportunities — lack of adding an mp3 jack to the car, Fast feedback enables smaller queues — use buffers but don’t go wonkers, Use fast feedback to make learning faster and more efficient – sailing two nearly identical ships to see the difference, What gets measured may not get done — just because you have a metric doesn’t mean it will help you, We don’t need long planning horizons when we have a short turning radius — don’t be the B-1, To detect a smaller signal reduce the noise, Control the economic logic behind a decision not the entire decision — reduce 1 lb of weight is work $300 of increased unit cost, Whenever possible make feedback local — local wip of kanbaan vs global wip of toc, Have a clear, predetermined economically-justified relief value, Embed fast control loops inside slow loops, Keep deviations within the control range — if testing Q gets too big as for more tests, To minimize queues provide advance notice of heavy arrival rates, Colocation improves almost all aspects of communication, Large queues make it hard to create urgency, The human element tends to amplify large excursions – homeostatis, To align behaviors, reward people for the work of others, Number of processes with alternative routes, Build and test as much of the system as possible, Break down the problem by using service virtualization to isolate different parts of the system, Pick a subset of testing for fast feedback before promoting to later stages for more extensive testing. At first I did not understand this concept as it seems counter intuitive, but (to a point) the less we did, the more we accomplished. Make tasks and resources reciprocally visible at adjacent processes. Product development queues are more insidious because they tend to be invisible. Control parameters that are both influential and efficient – … Make nested cadences harmonic multiples. Nest reporting in the monthly, quarterly, and yearly.

The Principles of Product Development Flow is destined to become another product development classic. Use synchronized events to facilitate cross functional trade-offs. Have a good economic framework so that tradeoffs are easy to make, Interconnected Variables. Disney says you have a 30 min wait from here, not a queue size. All this manual QA pays off, and now things are good-to-go to prod. Optimal learning happens when you fail half the time. Match. Reinertsen starts with the ideas of lean manufacturing but goes far beyond them, drawing upon ideas from telecommunications networks, transportation systems, computer operating systems and military doctrine. In contrast operating to the right of the throughput peak promotes stability because of a negative feedback effect.

You can see that although not entirely perfect yet, via TDD, our web-based deployment teams have made great strides in the past 4 years by developing a regular cadence and carefully managing the tasks and bug lists in their Jira queues. The author has written this book to show that the dominant model for managing product development is wrong to the core. First run unit tests, static code analysis, second run service or api tests, lastly test the User Interface. TERM: Orchestrator: Tool that coordinates all of the automation. She always refused work even when there was capacity left over so that she could respond if needed. Schedule frequent meetings using a predictable cadence. Product Development Payoff-function, CONCEPT: Metrics for flow-based product development. [page 169] In other words, we also need to fix issues in the work we are currently actively involved in. Principle #1: Take an economic view. Reinertsen argues that queues are the most important factor in maintaining optimal product development flow. Spell. The Principles of Flow “It ain’t what you don’t know that gets you into trouble. He explains why invisible and unmanaged queues are the underlying root cause of poor product development performance.… Flashcards. We then gather a very unhappy engineering corps to start working on the issue over the weekend, all while receiving, what seems like every minute, requests for an update on the issue. To enable synchronization, provide sufficient capacity margin. Watch Queue Queue Here's a recent story shared by Nathan Murith, Software Development Manager on BIM360. This is a meeting where all the stakeholders are invited: development leads, architects, QA leads, Product Management, Operations, Customer Support, my sister — you get the idea.

The Principles of Product Development Flow will forever change the way you think about product development. TDD is "a software development process that relies on the repetition of a very short development cycle: first, an (initially failing) automated test case is written that defines a desired improvement or new function. Instead, you can download the first chapter for FREE. The Principles of Product Development Flow is an important and thought-provoking book. As such, Chapter 7 proposes that the strategy for doing so involves getting projects into a regular cadence to improve workflow. And then it's all-hands-on-deck, with QA and engineering in a lengthy, manual process of testing and validating the build that was just pushed to staging. In 2016, we push dozens of times a day. Doing so reduces overhead and allows project checkpoints to occur at regular intervals instead of on targeted milestone completion dates. Easier to see when the marginal value equals (crosses) the marginal cost, CHART: Sequencing Risk Reduction. When job durations are equal, do the highest cost of delay first. He wants us to know why the rules of product manufacturing don't work for product development.

Many companies approach product development as if it were manufacturing, trying to control costs and improve quality by applying zero-defect, efficiency-focused techniques. And of course, we have been in code freeze for the past 2 weeks, which gave our small army of QA personnel time to test the code we are just a few days from releasing. Validate the fix.
