It's also a frustrating, condescending, and self-important book. We leave the office on these deployment Fridays with a number of people having volunteered to be on-call over the weekend because something is bound to go wrong. Optimal learning happens when you fail half the time. All this manual QA pays off, and now things are good-to-go to prod. Posted by Scott Sheppard at 04:00 AM in Books | Permalink, Tags: It's Monday morning, and we're already hearing buzz (read nervousness) around our upcoming, end-of-week, quarterly release. And then we go through the exact same drill: we wait, Ops does the deployment, engineering and QA remain in a state of readiness. Fix that last bug. — Don Reinertsen, Principles of Product Development Flow. Principles of Product Development Flow is organized into nine sections. The Principles of Product Development Flow Second Generation Lean Product Development By Donald G Reinertsen . The later we bind demand to resources, the smoother the flow. This Monday almost immediately turns into a "let's schedule meetings for the rest of the week so we can discuss all remaining issues and coordinate the release" kind of day. On page 1 of this book, Reinertsen states his ambition for the book: “I believe that the dominant paradigm for managing product development is fundamentally wrong….I believe a new paradigm is emerging… SUMMARY: This chapter attempts to summarize Jez Humbles’s book. Product focused is high volume, low varietyprocesses. But the deployment does complete to staging, and this is communicated to the team by emails coming from various distribution lists, aliases, an automated Jira system, Ops monitoring tools, etc. We never feel comfortable declaring success with any deployment. The Principles of Product Development Flow – Chapter 1. Develop and maintain alternate routes around points of congestion. CONCEPT: Configuration is under revision control to ensure repeatability. You may freely distribute this document, in either electronic or print form, but may not use it commercially or use it to make derivative works. My phone starts ringing. I am in the process of reviewing each chapter. Easier to see when the marginal value equals (crosses) the marginal cost, CHART: Sequencing Risk Reduction. The Principles of Product Development Flow: Chapter 1 Make nested cadences harmonic multiples. Customer support requests and emails start pouring in. Use of a regular, predictable rhythm within a process, TERM: Synchronization. Control parameters that are both influential and efficient – … The principles of product development flow draw on insights from Lean Manufacturing as well as examples from the Telecommunications and Computer Operating Systems industries. Principle #1: Take an economic view. Donald Reinertsen has some vital knowledge to pass on. This is something I learned from Theresa King at Verizon. The Principles of Product Development Flow will forever change the way you think about product development. Ask 10 people Ask them to independently estimate what it would cost the company, in pretax profit, if their project were 60 days late to the market. Use a regular cadence to limit the accumulation of variance. Change ), You are commenting using your Twitter account. Provide sufficient capacity margin to enable cadence. Use pricing to reduce demand during congested periods. Product development queues are more insidious because they tend to be invisible. Use flexible resources to absorb variation. He explains why invisible and unmanaged queues are the underlying root cause of poor product development performance.… The book may also be available from your local library. To reduce queues, synchronize the batch size and timing of adjacent processes. CONCEPT: Controlling the flow under uncertainty, TERM: Cadence. TERM: Scripted Deployment: Process of scripting the deployments across all environments. Synchronization causes multiple events to happen at the same time, CONCEPT: FIFO queues work well for similar task durations and similar costs of delay, CONCEPT: WSJF: Weighted Shortest Job First. STUDY. If you run everything “efficiently” at full capacity, then you have no bandwidth for innovation or flexibility. Part 7: Controlling Flow Under Uncertainty. Change ), You are commenting using your Google account. Have a good economic framework so that tradeoffs are easy to make, Interconnected Variables. Grab all reviewers and put them in the same room. Then, the minimum amount of code is written to pass that test, and finally, one refactors the new code to acceptable standards." First run unit tests, static code analysis, second run service or api tests, lastly test the User Interface. There is a sparse number of QA members on our team. PLAY. Blog trolls do their thing. Achieving the goal of Lean—that is, the shortest sustainable lead time with the best quality and value to people and society—requires understanding the economics of the mission. 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. When delay costs are equal, do the shortest job first. Did I mention that small batch sizes reduce risk? International flight must have enough delay from connecting flights.

This set of principles dispels this misconception. When both job duration and cost of delay are not homogeneous, use WSJF, When task duration is unknown, time-share capacity, Only preempt when switching costs are low, Use sequence to match jobs to appropriate resources. We can only resynchronize to a regular cadence if we have sufficient capacity margin. An introduction to Lean Product Development Flow given by Don Reinertsen at Adventures with Agile in London. You can’t change just one thing. ( Log Out /  A business plan writer should analyze the environment in which they anticipate operating at each of the s ocietal, i ndustry, m arket, and f irm levels of analysis (see pages 51–60). Avoiding bottlenecks typically requires action at a point before where a bottleneck occurs. We can't have developers working on other features or bug fixes since we are in code freeze. Consulting and Software Development Exposed to several industries Running VanDev since Oct 2010. I had a clarification question from Chapter I from the book, Principles of Product Development Flow. And for the past 2 years, our weekends are exactly that: ours. Figure 5 – Business Plan Development Process (Illustration by Lee A. Swanson) Essential Initial Research. Use forecasts of expected flow time to make congestion visible. Use cadence to make waiting times predictable. Inventory is the biggest waste, U-Curve principle: important trade-offs have a U curve, Imperfection: imperfect answers improve decision making, Small decisions: influence the many small decisions, we focus on the big decisions, First perishability principle: many economic choices are more valuable when made quickly, Subdivision principle: inside every bad choice lies a good choice, Early harvesting: harvest the early cheap opportunities, First decision rule: use decision rules to decentralize economic control, First market: decision makers must feel both cost and benefit, Optimum decision timing: every decision has optimum economic timing, Marginal economics: always compare marginal cost and marginal value, Sunk cost: do not consider money already spent, Buying information: the value of information is its expected economic value, Insurance principle: don’t pay for more insurance than the expected loss, Newsboy principle: High probability of failure does not equal bad economics.

Hartley’s forumula. For those who hunger for a rigorous approach to managing product development, Donald Reinertsen's book is epic. In a previous blog article, I mentioned how I was getting back to my programming roots and reading The Principles of Product Development FLOW: Second Generation Lean Product Development by Donald G. Reinertsen. The second call is usually around planning when we think we can push the fix. 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. We sleep in, we relax, and basically enjoy the two days of rest. Work late. Condition the flow just before the bottleneck. After another "Go/No Go" meeting, we confirm that the deployment will happen later that afternoon. Sequence first those activities that remove the most risk for the least expense, CHART: Economics of Parallel Paths. Did I fail to mention that this is what occurred for most of our releases 4 years ago? (See Principle B4: The Batch Size Risk Principle.) Select and tailor the sequence of subprocesses to the task at hand. The Principles of Product Development Flow: Second Generation Lean Product Development by Donald G. Reinertsen. Disney says you have a 30 min wait from here, not a queue size. Development (By-Donald G. Reinertsen). Actually, there's a lot more to it than that. The Principles of Product Development Flow is an important and thought-provoking book. If you've ever wondered why agile or lean development techniques work,The Principles of Product Development Flow: Second Generation Lean Product Development by Donald G. Reinertsen is the book for you. For over 25 years he has been recognized as a leading thinker on product development issues.This book begins where other books on product development end. We start the meeting by going around the table and asking everyone if they are ready and feel comfortable with tomorrow's release. Doing so reduces overhead and allows project checkpoints to occur at regular intervals instead of on targeted milestone completion dates. When our change fails to produce benefits, we revert to old ways, Risk adversion will drive innovation out of our development  process, Failure to correctly quantify economics: Avoid vodoo economics and understand your costs, Blindness to Queues: Not visible like boxes in a warehouse, Worship of efficiency: need spare bandwidth, Hostility to Variability: kills innovation, Worship of conformance: live in an uncertain world, Institutionalization of large batch sizes: illusion of efficiencies, Underutilization of Cadence: lowers transaction cost, Managing timelines instead of queues: emphasize flow you focus on queues rather than timelines, Absence of WIP constraints: best way to manage queues, Inflexibility: high capacity leaves you inflexible, Noneconomic flow control: economic frame resolves scheduling dilemas, Centralized Control: value efficiency over response type, Economics: key is to think the problem through, Variability: reduce variability and the cost of variability, Batch Size: reduce batch size, single most effective way to reduce queues, Cadence, Synchronization, and Flow Control: Regular intervals, start/stop times, and sequence, Quantified Overall Economics. Find new bugs. In 2016, we push dozens of times a day. As such, Chapter 7 proposes that the strategy for doing so involves getting projects into a regular cadence to improve workflow. We are all anxious to get home and enjoy the weekend, but there's still a slew of very manual tests and regression checks we need to complete before claiming victory. TERM: Deployment pipeline: defines how new code is integrated to the system deployed. Let me preface this review by stating for the record that I read a lot of non-fiction books. Celeritas Publishing, 2009, 304 pages, $29.14 (Kindle $27.68) Reviewed by Tom Bellinson . Very often we have to repeat this entire process multiple times because the hot fix broke something else that now requires its own hot fix. ( Log Out /  This chapter provides three examples of specific system development that illustrate application of human-system integration (HSI) methods in the context of the incremental commitment model (ICM).The examples are drawn from the committee’s collective experience and specific application of the concepts developed during our work to these particular projects. The definition of this is the total amount of profit we reap from a product through its lifetime. Rinse and repeat Tuesday, and then again on Wednesday. Chapter 1. TERM: Scripted environment: Scripts are created to configure everything from the O/S to the container. In a manufacturing environment, work in process (WIP) inventory build up is easy to see. Use with specialty. Use synchronized events to facilitate cross functional trade-offs. It becomes very low at both low and high speeds. TERM: Orchestrator: Tool that coordinates all of the automation. Eligible for Cash on Delivery. It is guaranteed to change the way you think about product development. The first call is usually about what the issue is, who is impacted, how we can fix it, who can fix it and can we get it out to the customer before Monday. He identifies a dozen fatal flaws that plague existing product development, beginning with a failure to properly identify and quantify the economics of development cycles, and outlines how to address these issues.

Gravity. Learn. Monday, May 14, 2018 4:51 PM Reinertsen argues that queues are the most important factor in maintaining optimal product development flow. The deployment completes, and there's minimal impact on our customers. The Principles of Product Development Flow will forever change the way you think about product development. CONCEPT: Quickly locating the offending code down to the fewest number of developers possible is the basic principle that should drive the design. Controlling deployments even under uncertainty is alive in the lab. 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.

CONCEPT: Testing layers. Match. T-Shaped people. Our customers are delighted. Reinertsen has now written an important new book, The Principles of Product Development Flow — Second Generation Lean Product Development. [page 169] In other words, we also need to fix issues in the work we are currently actively involved in. Schedule frequent meetings using a predictable cadence. Our releases typically involve web components and apps, desktop connected applications, web services, mobile apps — the typical Autodesk setup. Lights on I-66 controlling cars in. When job durations are equal, do the highest cost of delay first. 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. CONCEPT: One common script that uses variables for everything. Since we're a cloud company, our customers never sleep, and there's always a customer who logs on over the weekend and runs into a bug, or worse, cannot access their data. Control occupancy to sustain high throughput in systems prone to congestion. Flashcards. Exploit economies of scale by synchronizing work from multiple projects. The Principles of Product Development Flow is destined to become another product development classic. In other words, instead of checking projects at the end of phases such as design complete or code complete, evaluate progress at the end of each month to determine where corrective actions are needed. § Long, continuous production runs § Glass, paper, tin sheets, lightbulbs beer and potato chips -Know how to characterize these three process strategies with regard; Chapter 7: Process Strategy. Only visit nodes that add economic value. The next sub-part is on continuous delivery architecture, then post-deployment validation and finally CD. CHART: Highway throughput is a parabolic function of speed. 2039 Ratings. Off-season hotels. He wants us to know why the rules of product manufacturing don't work for product development. The author defines the most important metric for us to focus on as life-cycle profits. Validate the fix. It’s what you know for sure that just ain’t so.” – Mark Twain. To enable synchronization, provide sufficient capacity margin. The third is, of course, the "Go/No Go" call for the hot fix, and no hot fix can be deployed without doing a post-mortem. Very often, issues get raised, which then postpones the deployment another week. Katherine Radeka. The Principles of Product Development Flow: Chapter 1 Note: when the density is too high, flow is inherently unstable since the feedback cycle is regenerative. The first one, The Principles of Flow, sets up the rest of the book by describing the problems with the current accepted best-practices of product development. The author has written this book to show that the dominant model for managing product development is wrong to the core. The Principles of Product Development Flow available to buy online at takealot.com. 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. Book Review Part 7: The Principles of Product Development FLOW: Second Generation Lean Product Development by Donald G. Reinertsen, « Feedback volume in the Autodesk Labs TPS Report, Project VUE Viewing for Navisworks graduates from Autodesk Labs to the App Center ». The chances of the deployment having issues and engineering needing to jump in and fix issues are extremely high and very likely. Many companies approach product development as if it were manufacturing, trying to control costs and improve quality by applying zero-defect, efficiency-focused techniques. When you read the title, "Controlling Flow Under Uncertainty," the first thing that probably comes to mind is eliminating bottlenecks (i.e., controlling flow) and putting out unexpected fires (i.e., uncertainty). [source: Wikipedia]. Nest reporting in the monthly, quarterly, and yearly. The word hot fix is no longer part of our dictionary. The book proposes a network-based approach to project management where collections of resources have the capacity to respond to large and small project tasks based on availability. Route work based on the current most economic route. Much more information here would have been useful and the lack of it reduces the value of the book. This comes from R.L. SUMMARY: Some very complex ideas are presented in just a few pages. Many ways to pay. Although unexpected work can include the need to generate a hot fix, it can also involve determining that the work is more involved than originally anticipated. Triage the new bugs. Here's a recent story shared by Nathan Murith, Software Development Manager on BIM360. In product development fast feedback is capable of altering this curve. | Digg This 7. Check out Volume 27, Issue 1. ... Article/chapter can be printed. Here are the common inter-related variables, Quantified Cost of Delay (COD). If we want, we can release to production at any time of day or night with virtually no impact to our customers. Chapter 6 covered applying work in process constraints so that projects avoid having too many tasks in progress. Principles of Management - Chapter 7. About Me Started programming in 1981 Owner of Enoki Solutions Inc. Doing so reduces overhead and allows project checkpoints to occur at regular intervals instead of on targeted milestone completion dates. Test. When Thursday comes around, our entire team waits for one thing and one thing only: the infamous "Go/No Go" meeting. 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. And this is in large part due to a focus on and adoption of Test Driven Development (TDD). Product Development: Fast Feedback reduces loss from bad outcomes and enables exploitation of good outcomes. CONCEPT: Fast Feedback. And that's exactly what happens. CONCEPT: Problems with the Current Orthodoxy, CONCEPT: Major themes in the book (these are chapters), CHART: Economic Batch Size: We do not need to find the perfect optimum to capture most of the value because it is a U-curve, CHART: Profit vs. Product Development Payoff-function, CONCEPT: Metrics for flow-based product development. The unit of measure should be life-cycle profit impact, which is the ultimate measure of product development success. As such, Chapter 7 proposes that the strategy for doing so involves getting projects into a regular cadence to improve workflow.

Summary. Reprint: R1205E. It starts with a list of terms and definitions. We go through our nth bug triage session, addressing enormous Jira backlogs, trying to figure out which is the last bug that is truly important so that we can fix and squeeze it into this release. 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. Book review: The Principles of Product Development Flow. Only now it's Friday, and our afternoon is quickly turning into early evening. Main 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.
