Lean development is a methodology that was first applied to manufacturing, but is now being applied to management, UX, startups, and to software development. Lean software development is the process of optimizing how value is created by reducing waste. In a published example, Scrum (Agile) teams leveraging Lean were twice as productive and experienced 40% fewer defects than traditional teams. By focusing on the big picture and reducing waste in development, Lean projects are more likely to be successful and to speed up time-to-market. In software engineering, however, the importance of learning was never in doubt, and lean development methodology, perhaps, only proven it once more.
Efficient quality management is a guiding principle in lean development methodology, as issues in this area lead to different types of waste. It is one of the essential things your production partner must focus on. Here, waste refers to things that don’t significantly affect the quality of the developmental strategies and the end products.

In the middle of the 20th century, the company made great strides in rationalizing the production of cars with clever work on waste. Experts believe that LSD philosophy is borrowed from manufacturing that has used “lean” methods to minimize waste and increase customer value. 5s System – It is designed to improve efficiency and productivity through a systematic approach and following its five S’s that stands for- Sort, Set, Shine, Standardize, and Sustain.
- These include at the individual level, as well as in departments, in interdepartmental operations, in the overall organization, and between the organization and its customers and suppliers.
- By eliminating waste, streamlining processes, and implementing efficient practices, it can optimize development time.
- Lean development focuses on reducing the 7 wastes in the manufacturing process — namely overproduction, waiting time, transportation, processing, inventory, motion, and scrap.
- In software engineering, however, the importance of learning was never in doubt, and lean development methodology, perhaps, only proven it once more.
- The translation of the Toyota production system into the lean application development principles started in the early 2000s with Mary and Tom Poppendieck.
- This is another lean principle that seems simple but requires discipline to implement.
It is necessary to avoid optimizing a specific part of the system functionality at the expense of its entirety. Test-driven development reverses the “build, then examine” technique. Tests are written before the code is developed, allowing an engineer to anticipate all potential outcomes while developing. Lean Software Development or LSD applies Lean principles to develop software.
Aligning The 7 Lean Principles Into Our Software Development Projects:
Customer feedback is the most effective approach to discovering what is important. Each new piece of functionality introduces a new chance for feedback that clarifies the customer’s goal or real changes to the requirements. Both in Agile and Lean the main idea is that while developers work on a project to best fulfill the demands of the customer, they should also spend time learning new skills and experimenting with new techniques. “Lean” generally refers to a set of knowledge usually called “Lean Manufacturing“. Today, it’s hard to believe, but the Lean concept now used across industries was first developed in Japan for Toyota vehicle production. The Lean principles outlined above are the foundation of Lean methods such as Lean startup, Lean UX, and software development.
In addition to empowering your team to devise solutions to complex problems, the framework supports proper screening and selection of the chosen solution. This in-depth approach ensures that you only focus on the most essential features and processes from the beginning. The same principle of pulling the development applies to end customers.
Lean Project Leaders
Instead of relying solely on extensive testing later, we start with quality as a critical requirement from the beginning, adding it at every step. Lean principles were first laid out by Toyota, the Japanese automotive manufacturing giant, to optimize development time and resources in their manufacturing process and eliminate waste. Organizations that use the lean approach should remember that its main focus is to streamline the software development process by removing activities that don’t bring value. Lean development focuses on reducing the 7 wastes in the manufacturing process — namely overproduction, waiting time, transportation, processing, inventory, motion, and scrap.
The development process is never perfect, and it should be constantly reviewed and optimized. Analyze it in terms of focusing on value at every stage (less time, resources, better quality, etc.) and tighten the flow. The goal is not to create a perfect process, which is impossible, but rather to always be https://www.globalcloudteam.com/ in a state of continuous improvement. Unfortunately, you can’t apply this to software development as learning is vital to the process. Engineers need to learn and improve the product every step of the way. Having the right knowledge (both technical and business) helps to make better data-driven decisions.

So the company managed to overtake leading competitors in the quality and price of manufactured vehicles. The result of this is that our project never suffers from negative impacts which emerges because of bad decision making. lean software development methodology Learn the five biggest challenges you can encounter when scaling design teams and how to be prepared before facing them. You can increase flow by limiting the amount of inventory sitting between steps in your process.
The measure of the maturity of a trustworthy IT company is the speed of responding to the client’s needs. It is recommended to deliver the product quickly and in small chunks by implementing them in individual iterations. After quick implementation, the customer will immediately know whether the implemented part of the product is what he thought about or whether the customer’s needs were not correctly read. Thanks to this, we will avoid painful changes in customer requirements. It means we need to focus on improving the entire process of delivering software and not just the development phase. This is another lean principle that seems simple but requires discipline to implement.
This LSD principle seems simple but needs discipline and focus to be implemented. Lean teams use a combination of the following tools to correctly document and retain valuable learning. For this, it is worth moving in small steps and checking the quality after each step. The human factor is one of the most important elements in successful software development. Software development is a process of mental work, so treat people as competent, motivated professionals, rather than professionals with narrow skills in writing code or drawing diagrams.
Lean software development is a software engineering approach that prioritizes waste reduction. Toyota developed it in the late 1940s and early 1950s as part of the Toyota Production System. Over time, like many other manufacturing enterprises from various sectors adopted it, the name evolved to Lean. The method was initially used to create software in 2003 with the publication of Lean Software Development.
Weaknesses of Lean Software Development
If so, choose one that operates by these software development lean principles. This is accomplished via tools like user stories, Kanban boards, and Agile approaches, which place a strong emphasis on communication, openness, and ongoing input. Lean software development encourages teams to collaborate in order to streamline their operations and continuously enhance their capacity to provide consumers with value.
