What is Lean Project Management ?

Lean project management covers a wide spectrum of concepts such as lean manufacturing, lean thinking, lean construction. Basically lean project management or lean production focuses on eliminating waste and other processes which are not adding value to the production. Although this philosophy was developed in Toyota Production System, many projects in various industries use lean tools and techniques to improve the processes. Many industries such as software, healthcare, finance, construction, business, defense etc. may gain the same kind of benefits that lean has achieved for manufacturing.



The Main Principles of the Lean Project Management and Lean Methodology

Most of the projects are behind the schedule and/or over budget. Lean project management establishes a system to analyze all the activities throughout the entire project life cycle. Understanding each activity and process helps to identify waste and non value added process. The keystone of Lean methodology is to improve profit and customer satisfaction by maximizing value and minimizing waste. Lean project management methods include Kanban, Lean Six Sigma, Deming Cycle for continuously improving the process.

3M’s (Muda, Mura, Muri) in Lean Manufacturing



Muda, Mura and Muri are the 3M’s widely used in the Toyota Production System and later on the concept of Lean to describe wasteful practices to be eliminated.

Muda (無駄) : is the wastefulness, uselessness,  non value adding work. The term “Muda” covers seven types of wastes. Below are the seven Muda’s

  • Transport
  • Inventory
  • Motion
  • Waiting
  • Over-Processing
  • Overproduction
  • Defects

Mura (斑) : is unevenness. Mura is the root cause of Muda. Because unevenness and irregularity cause wastes.

Muri (無理) : is overburden. Muri is overloading equipment and overusing workforce beyond their limits. Muri may be de result of Mura.

It is not very easy to identify all the wastes in the working environment. This increases the potential of risks arises. Elimination of waste is the main purpose of lean.

Lean Thinking



Lean thinking is to create a continuous value stream by using the resources effectively, reducing wastes, ensuring customer satisfaction. James P. Womack and Daniel T. Jones are the founders of The Lean Enterprise Institute (LEI). They recommend five principles in their book, Lean Thinking: Banish Waste and Create Wealth in Your Corporation to help organizations achieve success.

Lean thinking was borned in the manufacturing industry and influenced other industries like software, healthcare, construction because lean is an approach that effects everything an organization does.

Below are the main principles of Lean Thinking

Womack and Daniel T. Jones defined the five basic principles of lean thinking in their book “The Machine That Changed the World” in 1990. 

– Value (Identify Value): The first principle is understanding the value of a product from the customer’s point of view. The organization must understand what value the customer places upon their products and services. Determination of the value is based on the customers needs for the product.

– Value Stream (Map the Value Stream): Value stream is the entire flow up the products life cycle from raw materials through to the customer’s use. Creating a value stream map using visualization techniques, diagrams and charts are helpful to demonstrate the sequence of activities required to deliver the end product.



– Flow (Creat Flow): Main goal of this step is to improve the value stream and ensure that the value stream flows. Waste should be removed from the flow of the value stream. If the value stream stops at any point, waste may occur.

– Pull (Establish a Pull Approach): If the flow of the value stream is improved, time to customer can be improved. Pull principle helps to be sure that nothing is made ahead of time. In the traditional manufacturing approach products are manufactured based on a schedule or forecast. But in the pull approach, the product is not manufactured until the customer orders it. As a result of this approach you don’t need to store large amount of products.

– Perfection (Seek Perfection): Prefection step is one of the most important step. Lean system requires continuous improvement and continuous improvement brings perfection because lean is a live process. Lean thinking should be every employees business and every process should be involved in lean.

Below figure illustrates the five principles of lean thinking.

Benefits of Lean Project Management and Lean Methodology



Lean manufacturing uses less resources compared with traditional production or mass production. Human efford, floor space, duration is decreased based on the effective use of lean principles. Below are some benefits of the lean project management.

– Develops a culture of empowerment
– Reduces manufacturing lead time

– Standartizes tasks and improves efficiency and project performance

– Helps to complete the project on time and budget with meeting customer requirements.
– Reduces costs
– Reduces inefficiencies and unproductiveness
– Improves quality of product
– Improves customer satisfaction
– Improves profit margin

Conclusion



Project management processes can be improved by the help of lean principles. A project can be thought as a value stream from the project managers point of view. Then the customer requiremets and satisfaction should be specified. The project management team members must enhance the working environment by specifying and eliminating wastes in all the processes. Deming Cycle, 5 Why’s, Kaizen, 3M’s can be used to improve the processes for production.
