Lean development is the application of Lean principles to software development. Lean principles got their start in manufacturing, as a way to optimize the production line to minimize waste and maximize value to the customer. These two goals are also relevant to software development, which also:. Of course, there are some major differences between manufacturing and software development, as well; namely, that manufacturing deals with the production of physical goods, while the value being created in software development is created within the mind of the developer.

Guiding Principles of Lean Development

Lean development is the application of Lean principles to software development. Lean principles got their start in manufacturing, as a way to optimize the production line to minimize waste and maximize value to the customer. These two goals are also relevant to software development, which also:.

Of course, there are some major differences between manufacturing and software development, as well; namely, that manufacturing deals with the production of physical goods, while the value being created in software development is created within the mind of the developer. Applying Lean principles to knowledge work requires a shift in mindset in terms of how value, waste, and other key Lean concepts are defined.

Learn how these 7 Lean principles apply to software development practices. Sign up for a day free trial and you and your team can start building online Kanban boards today. Here is a brief summary of each of these principles, as well as practical tips on how to apply them in software development. One of the key elements of practicing Lean is to eliminate anything that does not add value to the customer.

There are seven wastes or muda defined in the Toyota school of Lean manufacturing. They are:. Tom and Mary Poppendieck translated those wastes to software development. Each of these wastes should be systematically eliminated in order to maximize customer value:. It might seem self-evident; every team wants to build quality into their work. In trying to ensure quality, many teams actually create waste — through excessive testing, for example, or an excessive logging of defects.

In recent decades, many Lean development teams have found success by applying the following Lean development tools to build quality into their work. The Lean development principle of Create Knowledge is another one that seems simple, but requires discipline and focus to implement.

This principle encourages Lean teams to provide the infrastructure to properly document and retain valuable learning. This can be done by using any combination of the following tools:. This Lean development principle is easily misused. Defer Commitment does not mean that teams should be flaky or irresponsible about their decision making. Rather, the opposite: This Lean principle encourages team to demonstrate responsibility by keeping their options open and continuously collecting information, rather than making decisions without the necessary data.

Every team wants to deliver fast, to put value into the hands of the customer as quickly as possible. Here are a few common culprits:. Lean development is based on this concept: Build a simple solution, put it in front of customers, enhance incrementally based on customer feedback. This is important, especially in software, because speed to market is an incredible competitive advantage.

The Lean principle of Respect for People is often one of the most neglected , especially in the fast-paced, burnout-ridden world of software development. It applies to every aspect of the way Lean teams operate, from how they communicate, handle conflict, hire and onboard new team members, deal with process improvement, and more. Lean development teams can encourage respect for people by:.

Suboptimization is a serious issue in software development, and is often a self-fulfilling prophecy. In their book, Mary and Tom Poppendieck describe two vicious cycles into which Lean development teams often fall. The first is releasing sloppy code for the sake of speed. When developers feel pressured to deliver at all costs, they release code that may or may not meet quality requirements.

This increases the complexity of the code base, resulting in more defects. With more defects, there is more work to do, putting more pressure on developers to deliver quickly… so the cycle continues.

The second is an issue with testing. When testers are overloaded, it creates a long cycle time between when developers write code and when testers are able to give feedback on it.

This means that developers continue writing code that may or may not be defective, resulting in more defects and therefore requiring more testing. As the antidote to suboptimization, optimizing the whole is a Lean development principle that encourages Lean organizations to eliminate these sorts of vicious cycles by operating with a better understanding of capacity and the downstream impact of work.

If our goal is to deliver as much value to our customers as quickly as possible, then we have to optimize our value streams to be able to do just that. To understand how to optimize our value streams, first we have to properly identify them.

After identifying how value flows through their teams, many organizations decide to organize their software development teams to be complete, multi-disciplined, co-located product teams, which enables them to have everything they need to deliver a request from start to finish, without reference to other teams.

This is an approach popularized by Spotify that has been adopted by many Lean organizations including LeanKit as a way to optimize the whole and increase the speed of value delivery.

These two goals are also relevant to software development, which also: Follows a repeatable process Requires particular quality standards Relies on the collaboration of a group of specialized workers Of course, there are some major differences between manufacturing and software development, as well; namely, that manufacturing deals with the production of physical goods, while the value being created in software development is created within the mind of the developer.

Eliminate waste One of the key elements of practicing Lean is to eliminate anything that does not add value to the customer. These are some of the most popular Lean development tools for building quality in: Pair programming: Avoid quality issues by combining the skills and experience of two developers instead of one Test-driven development: Writing criteria for code before writing the code to ensure it meets business requirements Incremental development and constant feedback Minimize wait states: Reduce context switching, knowledge gaps, and lack of focus Automation : Automate any tedious, manual process or any process prone to human error Create knowledge The Lean development principle of Create Knowledge is another one that seems simple, but requires discipline and focus to implement.

This can be done by using any combination of the following tools: Pair programming Code reviews Documentation Wiki — to let the knowledge base build up incrementally Thoroughly commented code Knowledge sharing sessions Training Use tools to manage requirements or user stories Defer commitment This Lean development principle is easily misused. To defer commitment means to: Not plan in excessive detail for months in advance Not commit to ideas or projects without a full understanding of the business requirements Constantly be collecting and analyzing information regarding any important decisions Deliver fast Every team wants to deliver fast, to put value into the hands of the customer as quickly as possible.

Respect for people The Lean principle of Respect for People is often one of the most neglected , especially in the fast-paced, burnout-ridden world of software development. Lean development teams can encourage respect for people by: Communicating proactively and effectively Encouraging healthy conflict Surfacing any work-related issues as a team Empowering each other to do their best work Optimize the whole Suboptimization is a serious issue in software development, and is often a self-fulfilling prophecy.

Нет никакого файла, который мог бы заразить ТРАНСТЕКСТ. - Вы ошибаетесь, сэр! - вскричал Чатрукьян. - И если он проникнет в главную базу данных… - Что еще за файл, черт возьми. Покажите мне. Чатрукьян заколебался.

Никому не показалось удивительным, что два дня спустя АНБ приняло Грега Хейла на работу. Стратмор решил, что лучше взять его к себе и заставить трудиться на благо АНБ, чем позволить противодействовать агентству извне.

Дверь приоткрылась на несколько сантиметров. Они держали ее что было сил, но сопротивление оказалось чересчур сильным и створки снова сомкнулись. - Подождите, - сказала Сьюзан, меняя позицию и придвигаясь ближе.  - Хорошо, теперь давайте.

Мозговой штурм был своего рода разведывательным экспериментом, который его создатели называли Симулятором причин и следствий. Сначала он предназначался для использования в ходе избирательных кампаний как способ создания в режиме реального времени моделей данной политической среды. Загруженная громадным количеством информации программа создавала паутину относительных величин - гипотетическую модель взаимодействия политических переменных, включая известных политиков, их штабы, личные взаимоотношения, острые проблемы, мотивации, отягощенные такими факторами, как секс, этническая принадлежность, деньги и власть.

Комната была пуста, если не считать старой изможденной женщины на койке, пытавшейся подсунуть под себя судно. Хорошенькое зрелище, - подумал Беккер.  - Где, черт возьми, регистратура. За едва заметным изгибом коридора Беккер услышал голоса. Он пошел на звук и уткнулся в стеклянную дверь, за которой, судя по доносящемуся оттуда шуму и гвалту, происходило нечто вроде драки.
