Ensure availability of the item to function as required at optimum costs; 2. Consider the safety and other mandatory requirements; 3. Consider any impact on the environment; 4. To uphold the durability of the item and/or the quality of the product or service considering the costs where necessary. LEAN MAINTENANCE FUNDAMENTALS BY CLT SERVICES © 2014
