Lean Software Development: Values and Principles
With those techniques, Pratt & Whitney was able to rapidly eliminate an $80 million backlog of part shipments and cut its inventory levels and manufacturing costs in half while doubling labor productivity. In manufacturing and the Toyota Production System, the underlying principles are known as the Toyta Way. Developing automated tests is a large piece of work that takes time and effort.
That said, some managers believe that the way developers feel at work is more a people issue than a development challenge. But this issue has such a big impact on development that it cannot be ignored. You can use this Lean practice to identify the steps necessary to complete the project, the critical paths, where delays tend to happen, and more. This way, you can set goals for improvement in every stage of work. Lean development also encourages testing as many times as possible – from unit tests within an application down to end-to-end tests responsible for checking the work of an entire application as a whole. The best way to improve the process may well be through an evolutionary change, one that allows for making small adjustments as often as necessary, as well as taking big changing steps.

One of the examples is our recent project – a self-assessment app for choosing an optimal career path called Xelfer. On this project we decided to design the project structure with separate environments for developers, QA, and production. After our DevOps team created a CI/CD pipeline, developers basically got a “button” they can press to deploy code after an automated build and test process.
There has been a traditional belief in most businesses about the decision-making in the organization – the managers tell the workers how to do their own job. In a work-out technique, the roles are turned – the managers are taught how to listen to the developers, so they can explain better what actions might be taken, as well as provide suggestions for improvements. The lean approach follows the agile principle[6] “build projects around motivated individuals […] and trust them to get the job done”,[7] encouraging progress, catching errors, and removing impediments, but not micro-managing. A tight partnership between UX, product management, and engineering is critical.

Lean is the process of applying a scientific experimentation approach to find optimal solutions to user problems. On the other hand, the Lean Agile methodology focuses on the people who use your application. It’s not simply about implementing a new method; it’s also about having the right people to make it work. Agile EDW team leaders will benefit tremendously if they can transcend the informal chasm between these two camps and borrow techniques as needed from both lean and Scrum/XP.
For a successful approach, it is important to address problems and conflicts with communication, feedback, and respect for team members. Code needs to be effectively tested and verified to increase the quality of the final product. This principle applies not only to the coding process but also to communication, which can be improved by providing regular feedback. The first is releasing poorly coded products just for the sake of speed.
Principle 1. Eliminate waste
Optimization should happen by keeping whole system (or process) in mind and shouldn’t optimize parts with the hope that it will optimize the whole by itself. Automate wherever possible i.e. automate anything which is routine like unit testing, integration testing, builds, installations. Leaders should listen to their team members and encourage https://www.globalcloudteam.com/ them to find solutions to the problems encountered. Use them to establish confidence in the correctness of the system at any time during development, at every level of the system. Manage Workflow rather than Task-based SchedulesThe best way to establish reliable, predictable deliveries is to establish reliable, repeatable workflows.
- In recent decades, many Lean development teams have found success by applying the following Lean development tools to build quality into their work.
- The most common methodologies are Agile, Waterfall, Extreme Programming (XP), and Lean.
- After World War II the Toyota company was on the edge of bankruptcy which forced it to adopt austerity measures.
- Kanban Tool provides powerful online Kanban boards with seamless time tracking and insightful analytics.
Instead, you can hold regular meetings after every short iteration. In software development, waste is anything that fails to bring any business value to the customer and improve the quality of your product. This article provides a comprehensive guide on what is Lean software development, its definition, the difference between lean and agile, the key principles and benefits of lean technology.

As a result, teams can build great applications that will last for years. It’s a ‘value-driven approach to handle the software development projects which provide the best possible solution to meet customer needs and run a sustainable business. It helps organizations build new features and functionality with less time, money, resources, etc. According to Mary and Tom Poppedniecks, sub-optimizing is one of those unfortunate tendencies that, though unproductive, still occurs often in traditional IT departments. Managers lean software development teams choose to break each issue into multiple constituent parts, which they then have their teams fix separately, without optimizing entire systems. The Lean approach to software development opposes that and focuses on the value stream.
The correct setup is crucial for your product, and you want to support customers as much as possible. Lean manufacturing allows factories to create a pipeline production where everything is standardized and simplified so that modification and re-learning are rarely needed. Eventually, other manufacturing organizations across many industries began using this system, and the name later changed to Lean.
Principle 6: Respect People
It’s worth devoting time, money and effort on the Lean implementation if you struggle with delivering value in a timely manner. It’s worth it, when you want to develop products faster, and in the meantime increase their quality. It’s also worth it when you want to save money and maximize the efficiency of your development team. The ‘Building quality in’ principle of lean software development addresses all such issues before they occur. Instead of relying solely on extensive testing later, we start with quality as a critical requirement from the beginning, adding it at every step. To identify and remove waste from your software development process, you must avoid making elaborate plans in advance.
The key concept here being value – by eliminating waste, one keeps only that which creates value. By applying an iterative approach to software development, we at MindK are able to check the result at each stage of the development, deliver working solutions to the client and receive feedback. In spite of the fact that the Lean manufacturing concept was created for the industrial tasks of Toyota, it quickly became clear that the principles worked not only for the automotive industry.

Lean approach requires streamlining the entire workflow to improve overall team performance and achieve the highest efficiency across all technology and business areas. Toyota developed it in the 1950s to optimize production processes by eliminating any steps that didn’t contribute to the quality of the final product. Today, Lean is widely used and lean software development has been most widely adopted in software development. While both methods promote productivity and fast delivery, we highly recommend that you understand the dissimilarities in their guaranteed correct application. The lean methodology can be applied to considerably reduce programming effort, budgeting, and defect rates in software development.
