Dear Krishnendu Kar,
Your query is about designing a vision and mission statement for your department, i.e., the kitchen. It has been clarified already that these statements are for the organization and not for any department. If every department were to have independent vision and mission statements, there is a chance of a clash of the statements and, consequently, conflict among departments.
Total Quality Management (TQM) as an Alternative
However, instead of designing vision or mission statements for the kitchen, you may start practicing Total Quality Management (TQM).
Many companies, after acquiring ISO certification, just stop at that. However, the quality journey should continue, and the next stop should be TQM. The destination is the creation of an organization-wide quality culture.
Steps to Attain TQM
a) Inspection for error detection and rectification
b) Quality control through (i) statistics, (ii) process analysis, and (iii) quality standards
c) Quality assurance through (i) quality systems, (ii) quality costing, (iii) problem-solving, and (iv) quality planning
d) Total Quality Management (TQM): TQM takes the concept of quality to the level of philosophy. The philosophy is fostered by (i) considering quality as strategic, (ii) teamwork, (iii) staff empowerment, and (iv) involvement of customers and suppliers.
Developing a culture of quality is no easy task, and it could take years. To attain a culture of quality, the concepts of quality cannot be restricted to just functional activities but making "quality" a bylaw or a way of life.
Thanks,
Dinesh Divekar
