Interface’s Lean Product Development Journey




Interface is a manufacturer of modular carpets from LaGrange, Georgia, USA. The company started its Lean Product Development Journey as part of the new business strategy, a Directive Mission Zero established by its chairman and CEO in 1994.

The Lean Analytics Association (LAA) team carried out an interview and Gemba walk at Interface facilities to document how it maintains an inviting environment for continuous improvement by establishing lean thinking best practices in the innovation process.

By reading further, you will learn how Interface ties lean to sustainability strategy and translates implementation efforts into business results and find out where to find more details about their Lean Product Development journey.

InterfaceInterface is the world’s largest manufacturer and marketer of modular carpets. The company’s modular carpet systems, marketed under the established global brands Interface and FLOR, utilizes carpet tiles cut in precise, dimensionally stable squares or rectangles to produce a floorcovering that combines the appearance and texture of traditional soft floorcovering with the advantages of a modular carpet system.

Interface is maintaining its position among top sustainability leaders due to company’s business strategy focused on sustainability through the Mission Zero strategy concentrated on people, process, product, place and profits.


“To be the first company that, by its deeds, shows the entire industrial world what sustainability is in all its dimensions: People, process, product, place and profits — by 2020 — and in doing so we will become restorative through the power of influence” Mission Zero (Ray C. Anderson, 1994)”

To support Mission Zero and guide everybody on the path of accomplishing the company’s goal, the Seven Fronts of Mount Sustainability were identified and placed on a framework to align and remind employees the fronts through which the company needs to pass to reach its mission before 2020.

Lean thinking is also embedded in this strategy, complementing the sustainability efforts and is particularly used in the Custom Design Studio which works on engineer-to-order flooring solutions. The department leveraged lean best practices to improve the design process from manufacturing experience at Interface’s Pilot Plant.

Through its journey, Interface established best practices in several aspects of Lean Product Development. These practices were identified and structured according to the four building blocks of the Lean Innovation Model. Below are just some of the best practices identified and described in the Interface chapter of the Lean Product Development Best Practices Book.


The concepts Interface is using to develop new processes are fully aligned with both sustainability strategy and lean thinking.


The product development area at Interface includes cross-functional teams of experts working together and relying on the rest for an accurate and timely information transfer to maintain reliable and short product development cycle times delivering innovative solutions to its customers.


Interface frontloaded the design process and created a Kanban system that allows job allocation according to the complexity and the designers’ level of skills. Through Kaizen events, the team initiated a continuous improvement process to ensure the customer needs are understood and their wishes are translated to the “designers’ language” accurately. To encourage collaboration and co-creation of knowledge, Interface has introduced an internal social media platform that serves as a knowledge co-creation space and sharing space. Its use is encouraged by Top Management and it is seen as an opportunity for positive self-promotion and achieving recognition by peers throughout the company.


Continuous improvement at Interface is a vital part of the company’s vision: 10% of employees working time in product development is assigned to continuous improvement activities.

Impact of applying Lean Thinking in Product Development

After the Design Studio at Interface started to measure the benefits of using lean thinking to improve custom design processes, the following benefits have been observed:

  1. The number of custom samples created increased from 30,750 in 2013 to an estimated 32,250 in 2015.
  2. Digital sample cycle times were reduced from 1.7 days to an estimated 0.5 days per sample
  3. Physical sample cycle times were reduced from 3 days to 1.8 days

Interface’s Best Practices are presented and described on more than 25 pages in the Lean Product Development Best Practices book. Interface’s chapter is only one out of the 10 chapters presenting the real-world application of lean product development in multinational companies.

The hard copy of the book with the 10 cases is available for only 74.99 EUR.
