Timeline

Company-wide Quality

Kaoru Ishikawa built on Feigenbaum’s concept of total quality and suggested that all employees have a greater role to play, arguing that an over-reliance on the quality professional would limit the potential for improvement. Maintaining that a company-wide participation was required from the top management to the front-line staff. As every area of an organization can affect quality, all areas should study statistical techniques and implement as required with internal and external Quality Audit programmes. Going on to name areas such as engineering, design, manufacturing, sales, materials, clerical, planning, accounting, business and personnel that can not only improve internally but also provide the essential information to allow strategic management decisions to be made concerning the company.

Under the “company-wide” Ishikawa umbrella are not just a company’s internal quality control activities but the company itself, the quality of management, human respect, after sales service and customer care. Therefore suggesting the following benefits:
