Continuous improvement & 5S 2.0 for Product Development in CAREL
CAREL, an Italian HVAC/R introduced the Lean to the Product Development process back in 2009. After the R&D reorganization, implementation of visual project management and establishment of PDCA, CAREL decided the need to do more to support its product development teams. In 2012 company launched two Continuous Improvement (CI) initiatives: (1) Dedicated time for CI activities within “focus areas”, and (2) 5S 2.0 initiative for R&D workplace stabilization, maintenance and improvement. Continue reading to find out more about CAREL’s way to continuous improvement, 5S 2.0 and how this affects their product development.
CAREL is one of the world’s leaders in control solutions for air-conditioning, refrigeration, heating, and systems for humidification and evaporative cooling. CAREL prides itself as the company with a mission is to bring energy savings and reduce the impact of machinery and systems on the environment.

In 2007-2009, during the global economic crisis many companies were facing the challenge to remain competitive, but CAREL kept growing. This growth meant that leadership was required to find a solution, effective and flexible enough, to support that growth. They found the answer in the Lean Product Development approach.
CAREL takes continuous improvement very seriously and everyone in the company commits to it, from executives to shop floor workers. This helps the company to keep in touch with the latest technologies and scientific discoveries, enabling CAREL to stay ahead of its competition. To nurture this culture, CAREL introduced a dedicated time for continuous improvement across all product development teams. The company assigns 20% of employees’ time, solely to improving their “focus areas”. This means that no matter to which project an employee is currently assigned, they will dedicate their 20% of time to work on the improving a specific “focus area” they belong to. Regardless of their project tasks. This type of system provides multiple benefits besides regularly reviewed and updated “focus areas”. One of the key advantages, CAREL likes to point out, is that when you put together employees from the same “focus area” but from the different projects, they all have their own views and suggestions, influenced by their experiences, people they work with (on projects), and work they do. Having this diversity truly drives innovation and continuous improvement within CAREL.

Additionally, CAREL applies a systematic approach called 5S to stabilize, maintain and improve its working environment across offices as well as production lines. This helps the company create an efficient and safe work environment. The 5S technique is based on five Japanese words: seiri, seiton, seiso, seiketsu and shitsuke. These words can be translated in English as: sort, stabilize, shine, standardize and sustain.
- SEIRI (SORT): Separate useful and useless things; eliminate useless things.
- SEITON (STABILIZE): Set useful things in order, so that other people can understand where their place is. “A place for everything and everything in its place.”
- SEISO (SHINE): Clever cleanliness of the workplace: reinstate and define optimal operative conditions.
- SEIKETSU (STANDARDIZE): Communicate standards and correct operating methods in the simplest and most effective way.
- SHITSUKE (SUSTAIN): Respect the defined standards and apply the first 4S in order to keep and improve the results.
To distinguish its 5S initiative in product development from the shop floor initiative, CAREL decided to name the product development one a “5S 2.0”. The company’s goal is to ensure 5S sustainability over time by analyzing and reviewing existing standards, extending 5S to the environments that are still not included, and by implementing an auditing program for every single group of desks.
How does it work? A 5S team leader (a person from each “group of desks” – previously defined) raises possible issues and encourages his/her colleagues to resolve them collaboratively. The same 5S team leader is also required to perform a weekly self-audit on his/her own group of each desk in the predetermined period of time, after which a new 5S team leader is selected.
CAREL estimates that the combination of these two approaches and their consistency results in three-hour savings in cycle times for every hour invested in continuous improvement.

CAREL’s Best Practices are presented and described on more than 25 pages in the Lean Product Development Best Practices book. CAREL’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.
CAREL’s Lean Product Development case is available digitally free of charge to our members.
