Such systems are complex, and they consist of many interrelated components. In SAFe, systems thinking is applied to the system under development, as well as to the organization that builds the system. For this, it is worth moving in small steps and checking the quality after each step. An interesting business function which went into production in a few months can ultimately prove to be completely useless. But if it was released within two weeks, it could prove beneficial to the customer. All decisions must be supported by analytical data and process monitoring results, otherwise the team risks being absorbed in too many changes and may forget about the project’s main purpose.
- Eliminating waste (lean six sigma method) and group cohesiveness (Agile method) are positive attributes that any project could benefit from.
- According to the principles of lean development, a problem can either be found after its appearance, or you can eliminate the causes leading to a problem in advance.
- As a result of implementing this approach, organizations saw faster end product delivery, higher customer satisfaction, superb team collaboration, and considerably better quality.
- Often used with other agile methodologies like Scrum or kanban, a lean approach streamlines the development process.
- They have to constantly track the software development processor that are no bugs in the intermediate and final products.
The term was first used in a book by the same name written by Tom And Mary Poppendieck in 2003. It aims at removing everything that is unnecessary, or that does not bring value to the end product. Business owners, developers, and customers have a shared responsibility to ensure that investment in new solutions will deliver economic benefits. The sequential, phase-gate development model was designed to meet this challenge, but experience shows that it does not mitigate risk as intended. In Lean-Agile development, integration points provide objective milestones at which to evaluate the solution throughout the development life cycle.
Applying It To Lean Software Development
It’s based on the idea that every business represents a value stream – the sequence of activities required to design, produce, and deliver a product or service to customers. 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. Suboptimization is a serious issue in software development, and is often a self-fulfilling prophecy.
If some activity could be bypassed or the result could be achieved without it, it is waste. Partially done coding eventually abandoned during the development process is waste. Extra features like paperwork and features not often used by customers are waste.
Respect for People
Lean software development is standardly described as an Agile methodology. But Lean significantly pre-dates the Agile Manifesto, which was only written in 2001. Defected or buggy software introduces waste in the form of repeating work and low customer satisfaction. Unclear or changing requirements result in focus being lost, work being repeated, frustration and, ultimately, a drop in quality of the software produced. Extra processing is incompetent or unnecessary additional process steps that add no value to the development process. Take time to have one-on-one meetings with each engineer and learn what their independent goals are.
Lean software development is an iteration methodology initially developed for the manufacturing industry to optimize production and avoid waste. Many of the principles and practices in Lean Software Development came from the lean enterprise movement and was initially used by big companies like Toyota. Instead of relying solely on testing and bug fixing, lean encourages building quality into your product from the beginning.
The history of Lean development
Since both types of decisions occur, creating a reliable decision-making framework is a critical step in empowering employees and ensuring a fast flow of value. Delivering the ‘best value and quality for people and society in the shortest sustainable lead time’ requires a fundamental understanding of the economics of building systems. This includes the strategy for incremental value delivery and the broader economic framework for each value stream. This framework highlights the trade-offs between risk, Cost of Delay (CoD), manufacturing, operational, and development costs. In addition, every development value stream must operate within the context of an approved budget and be compliant with the guardrails which support decentralized decision-making. While these two methodologies differ in certain respects, each of these principles can add value to your work processes.
The process was first formally documented for the general public by the book Toyota Production System (TPS), published by Ohno in 1978. Similarly, in our example, if the chef creates some dish which is very tasty, appreciated by the customers and gets repeated orders, its recipe must be shared with the rest of the chefs. It would be a delight for the rest of the chefs to learn what Chef did differently to make it taste great. Also, this will make the rest of the staff equipped to prepare an equally tasty dish in his absence. Work doesn’t add value to the customer until its complete, which, in turn, keeps the resources occupied. Moreover, until and unless it is not complete, we can’t figure out whether it will work or not.

Waste refers to any activity or resource that doesn’t add value to the final product. Examples of waste include unnecessary code, redundant features, and excessive documentation. Eliminating waste helps streamline lean software development principles the development process and optimize resource usage. Lean software development is an approach to software creation that focuses on delivering maximum value to customers through resource and process optimization.
You must ensure that your resources are being utilized to the best of their ability at all times. In his book 10x Marketing Formula, Garrett Moon says that pre-approved workflows are the key to speeding up your software development methods and life cycle by 10x. Sometimes this means providing additional training, team bonding, or streamlining communication processes.
What is Lean Software Development?
The Lean methodology strives to develop quality in a controlled, disciplined way. It’s an easy way to take stock of your team’s workload and ensure that you’re utilizing their talents effectively. They can test, experiment, make changes, incorporate feedback and — most importantly — fix mistakes before they become more difficult to undo.
Teams need to acquire the necessary knowledge and expertise to effectively implement lean principles. A collaborative and respectful work environment, promoted by lean principles, can lead to higher employee morale and job satisfaction. Rather than waiting for a complete, fully featured product, teams release smaller increments or iterations to gather feedback from users. This approach allows for faster validation of ideas and provides opportunities for continuous improvement based on real-world usage. The goal of the method is to make software development flexible so that developers can always act according to the latest knowledge without undoing previously performed actions.
A brief history of Lean as a software development methodology
Interruptions can encompass everything including escalated customer requests, urgent questions from team members, meetings that another team member adds to their calendar, outages, and more. To limit waste from hand-offs, reduce the amount of back-and-forth between people on a project. Avoid having more projects in progress at once than is necessary to reduce inventory waste. As soon as that tool becomes available, the extra hour is no longer required to create value for customers.
