To compare operating practices with norms prevalent in the industry the Benchmarking tool could be used: Norms /best practices Actual practice internal i.e., between functions, departments or a similar organization as a means of improving performance; competitive i.e., comparison across industries within a given sector aimed at establishing best practice through identification of gaps in performance. This can be done on product, functional, departmental or on a company-wide basis. comparativei.e., across all business sectors aimed at establishing best practice in all areas of operation (this type of benchmarking is restricted to common processes or technologies (sector non-specific) across business sectors) Benchmarking
For knit fabric industry the following norms are used: Energy consumption 70 MJ / Kg of fabric Dye consumption 4 g/Kg of fabric Water consumption 120 L/Kg of fabric Comparison With Norms to Identify Problem Areas
