Since the inefficiency is felt in production process, it will involve the correct management of input, as the raw material and labor inputs shall be proper.
Transformation process is vital as this will convert the input into output and accordingly shall include all the important steps required in production.
Output shall be maintained properly as and when the output is ready as shall be stored and packed properly.
Feedback forms are important to know the customer review about the products.
Therefore, design, sales etc: shall not be worked in course of improvement.
