By Lukashin Daniil (ddlukashin@edu.hse.ru)
Introduction
Lean modelling is a methodology aimed at simplifying and optimising the software creation process. This approach focuses on creating only those components and functions that are really important and useful for users and business.
This approach has become the most important methodology in software development to improve efficiency and reduce waste. Based on the Lean philosophy originally developed in the automotive industry, this trend aims to maximise value for the customer by optimising all development processes [1].
Unlike traditional methodologies such as Waterfall, Lean focuses on continuous improvement and the involvement of all participants in the development process in finding and eliminating losses [2].
Key principles of Lean include continuous process improvement, elimination of unnecessary steps, rapid delivery, and customer focus. These principles enable the creation of software that best meets user expectations and needs, while minimising the resources and time spent on development.
Applying Lean modelling in the corporate environment allows companies to not only reduce development costs, but also improve the quality of the final product. Examples of successful implementation of Lean in software engineering show that this approach can lead to significant improvements in productivity and customer satisfaction.
Basic principles of Lean
Lean modelling is based on a number of key principles that help to optimize software development processes and minimize waste.
At the heart of Lean is the concept of continuous improvement, or ‘kaizen’. This means constantly looking for opportunities to improve every aspect of the development process, from planning to implementation to testing. Implementing small, incremental changes can improve product quality and reduce costs.
Lean aims to identify and eliminate processes that do not deliver value to the end user. This involves analysing each stage of development to determine which ones can be simplified or eliminated. The goal is to focus only on those activities that directly contribute to value creation.
One of the key principles of Lean is to minimise the time between an idea and its implementation. This is achieved through the use of approaches such as Continuous Integration (CI) and Continuous Delivery (CD), which allow regular product updates and improvements to be released. Rapid delivery helps to respond faster to changes in customer requirements and wishes.
Lean puts the customer at the centre of all processes. Understanding and satisfying customer needs is prioritised. This includes getting regular feedback from users and using it to improve the product. The main goal is to create a product that best fulfills the expectations and needs of the end user.
Lean in enterprise IT projects
Lean modelling is becoming increasingly popular among corporate IT projects due to its ability to significantly increase efficiency and reduce costs. Implementation of Lean principles in large organisations allows not only to improve development processes, but also to ensure that the software created better meets the needs of users.
One of the key examples of successful application of Lean in corporate IT projects is Toyota, which has implemented Lean principles to improve its IT processes. Using approaches such as continuous improvement and loss elimination, Toyota was able to reduce development time and increase the quality of software products [6].
Another example is Intel, which used Lean to optimize its software development processes. By implementing Lean, Intel was able to significantly reduce development and release time and improve software quality through regular iterations and customer feedback [7].
Benefits of applying Lean to enterprise IT projects include:
Reducing development time Lean can significantly reduce software development and release time, which is especially important for enterprise projects with tight deadlines and rapidly changing requirements [6].
Improving product quality Continuous process improvement and regular customer feedback contribute to the creation of higher quality software, which increases user satisfaction and reduces bugs [7].
Resource Optimization Lean enables more efficient use of resources by eliminating unnecessary steps and focusing on activities that deliver maximum value. This helps to reduce costs and increase productivity.
Despite its many benefits, implementing Lean in enterprise IT projects can face certain challenges. These include the need to change the existing processes and culture of the organisation, as well as training employees in new ways of working. However, successful examples of Lean implementation show that such efforts can lead to significant improvements in productivity and software quality.
Comparing Lean with other methodologies
Lean methodology stands out among other software development methodologies because of its unique approach to minimizing waste and maximizing value for the customer. To fully understand the advantages and disadvantages of Lean, it is useful to consider it in comparison to methodologies such as Agile and Waterfall.
Agile and Lean have much in common, as both methodologies emphasize flexibility and rapid adaptation to change. However, there are also significant differences. Agile frameworks such as Scrum focus on fixed sprints and clearly defined roles, whereas Lean focuses more on continuous improvement and eliminating all types of losses [3].
Unlike Lean and Agile, the Waterfall or cascade model is a linear and sequential approach to software development. The main difference is that Waterfall assumes that one stage of development is completed before the next stage begins, which can make it difficult to make changes late in the project. Lean, on the other hand, promotes continuous improvement and adaptation throughout all stages of development [5].
Advantages and Disadvantages of Lean Advantages of Lean include the ability to adapt quickly to changes in requirements and cost reduction by eliminating unnecessary processes. However, implementing Lean can be difficult in large organisations where changes may be met with resistance and require significant effort to redesign existing processes [4].
Applicability in different contexts Waterfall can be useful in projects with well-defined requirements and deadlines where change is unlikely. Agile is suitable for projects with rapidly changing requirements and the need for regular iterations. Lean, on the other hand, is ideal for organisations that seek to continuously improve processes and minimise waste, while providing a high degree of flexibility [5].
Lean modelling tools and techniques help development teams focus on core product functions, avoid redundant documentation, and ensure rapid adaptation to changing conditions. These approaches focus on creating a minimum viable product, optimizing workflows and continuous feedback. Among the main tools of Lean modelling are the following:
The MVP concept is at the heart of Lean modelling. It is a minimal version of a product that includes only the most necessary features to start testing an idea and collecting feedback from users. The MVP avoids redundant development and allows us to get early feedback from the target audience, which is critical for adjusting the direction of the project in the early stages. By quickly launching an MVP, teams can respond quickly to changes in requirements and reduce development risks. This tool is the foundation for further iterative product improvement, helping teams avoid wasting resources on features that may be unnecessary.
User Story Mapping is a tool that allows you to structure a hierarchy of requirements based on the tasks the user wants to accomplish with the product. This approach helps to visualize the user's journey through the product and identify the key features that need to be implemented first. User Story Mapping helps teams understand user needs, prioritize each feature and avoid creating unnecessary details. In Lean modelling, it helps to structure work on the minimum required functionality.
Value Stream Mapping is used to analyse and visualize all steps of the development process, from the idea to the final product. This tool helps to identify steps that do not add value and allows the team to focus on actions that add value to the user. VSM helps to eliminate wastage, speeds up the development process and optimizes team resources [8]. This method is particularly useful in enterprise software development where resources need to be allocated efficiently and functional versions need to be delivered quickly.
Kanban is a workflow management method that uses a visual board to track tasks and improve their flow. The kanban board helps the team to track the status of each task, see the workload of the team and avoid bottlenecks. This tool is important in Lean modelling as it helps to avoid congestion and maintain an even developer workload. With Kanban, teams can react quickly to changes, optimize task flow and improve productivity.
Iterative design and Continuous Improvement are also key techniques of Lean approach. In Lean modelling, iterations allow teams to implement changes quickly and get feedback from users at each stage. This process maintains close interaction with the customer and helps teams adapt the product to their needs in a timely manner. Continuous Improvement minimizes waste and focuses on building only the features that are really needed, which is one of the key objectives of Lean modelling [9].
Conclusion
Lean modelling demonstrates significant benefits in enterprise software development, including increased efficiency, reduced costs and improved end product quality. The principles of continuous improvement, elimination of unnecessary steps, rapid delivery and customer-centricity allow teams to be more agile in responding to changes and user needs. Comparing Lean with other methodologies such as Agile and Waterfall highlights the unique benefits of Lean in minimizing waste and continuous process improvement. Lean modelling is a powerful tool for optimizing software development in an enterprise environment.
