A methodical way of elimination of waste, in the production

 SIX SIGMA
Six Sigma is a process of maintaining the desired quality in the
products and processes by taking necessary steps in this
regard.

What are the advantages of integrating
Lean and Six Sigma?
• Integrating Lean and Six Sigma creates a win win situation. The
philosophy of Lean provides the strategy and creates the
environment for improving flow and eliminating waste.
Empowered staff are encouraged to continuously improve to create
value adding opportunities that otherwise would not be
identified. ‫دمج‬‫اللين‬‫وستة‬‫سي‬‫ج‬‫ما‬‫فوز‬ ‫فوز‬ ‫حالة‬ ‫يخلق‬.‫فلسفة‬‫اللين‬‫استراتيجية‬ ‫توفر‬‫ويخلق‬‫بيئة‬

• Six Sigma helps to quantify problems, makes evidence based
decisions. ‫األدلة‬ ‫إلى‬ ‫تستند‬ ‫قرارات‬ ‫ويتخذ‬ ،‫المشاكل‬ ‫تحديد‬ ‫على‬ ‫يساعد‬ ‫سيجما‬ ‫ستة‬.
• helps to understand and reduce variation and identifies root causes
of variation to find sustainable solutions. Furthermore, it
quantifies the financial benefits and savings. This helps to focus
efforts in the areas that offer the most potential for improvement.

11. • A combination of both can provide the philosophy
and the effective tools to solve problems and create
rapid transformational improvement at lower cost.
Potentially, this could increase productivity, improve
quality, reduce costs, improve speed, create a safer
environment for patients and staff and exceed
customer expectations. ‫الفلسفة‬ ‫توفر‬ ‫أن‬ ‫يمكن‬ ‫معا‬ ‫االثنين‬ ‫من‬ ‫مزيج‬
