Lean IT focuses on maximizing customer value by minimizing waste, where waste is work that adds no value to a product or service. The mean focus is to achieve operational excellence through improved agility, service quality and process efficiency. It means building a customer and value-oriented culture in which employees engage in Lean IT processes. It also means involving all employees to continually improve services and preserve value with less effort and optimising IT operations and processes supporting the most business critical applications and services. Lean IT has a great impact on the culture of an organization with behavioral aspects such as empowering employees to involve them in the optimization of processes. The goal is to implement a rigorous problem solving process to achieve greater strategic and financial value.
There are many aspects of Lean IT within two primary dimensions:
• Outward-facing Lean IT: Engaging information, information systems, and the IT organization in partnership with the business to continuously improve and innovate business processes and management systems
• Inward-facing Lean IT: Helping the IT organization achieve operational excellence, applying the principles and tools of continuous improvement to IT operations, services, software development, and projects
These two dimensions are not separate but complementary. They serve the ultimate objective of Lean transformation: creating value for the enterprise and its customers.
Lean IT is based on enterprise Lean principles, laying a solid foundation at the base. The three foundation elements support a strong social structure; constancy of purpose, respect for people and pursuit of perfection. The second layer is proactive behavior which means taking the initiative, assuming personal responsibility for the quality of the work and work environment. The third layer addresses awareness, with three essential perspectives embraced by the Lean enterprise: the voice of the customer, quality at the source, and systems thinking. The fourth layer focuses on fl ow, the uninterrupted progression of materials, services, and information. The fifth layer, the capstone of the principles, is culture, which represents an organization’s shared beliefs and values, manifested as attitude and behavior. Culture is an outcome of behavioral change.
The principal focus of Lean IT is problem solving for the primary purpose of delivering value to the customer, achieved by the systematic elimination of waste throughout the value stream. A fivestep thought process for implementing Lean thinking refers to:
• Specify value from the standpoint of the end customer
• Identify all the steps in the value stream, eliminating whenever possible those steps that do not create value
• Make the value-creating steps occur in tight sequence
• As flow is introduced, let customers pull value from the next upstream activity
• As value is specified, value streams are identified, wasted steps are removed, and fl ow and pull are introduced, begin the process again and continue it until a state of perfection is reached in which perfect value is created with no waste
