Metal Casting Technologies : September 2005
DEFINITIONS A. Capability -- The quality of having the ability, capacity, and power to do something; competence. This involves the "inputs" to a process; the qualifications of an enterprise to carry out its objectives. B. Performance -- The execution of the required functions for effective operation; accomplishment. This involves the "outputs" of a process; the achievements of an enterprise vis-a-vis its objectives. Therefore, performance measure is a "standard of valuation which indicates how well the activities of a process or outputs of an enterprise achieve the specified goal." REASONS FOR PERFORMANCE MEASUREMENT A. Following are the reasons for measuring performance: 1. To know what is going on. 2. To identify performance gaps. 3. To provide feedback. 4. To correct poor performance. 5. To reward good performance. 6. To effectively make and support decisions regarding policies, resources, plans, schedules, and structure. B. In an enterprise, the following factors are measured to gauge performance: 1. The quality of the output. 2. The time it takes for processing. 3. The cost of processing the output. TECHNICAL FEATURE Prof. J. Hermes D. Bautista, PMAI Technical Consultant A suggested method for assessing foundry performance T CRITERION 1 (Key critical point): Capability to produce world-class castings. Sub-criterion 1: Ability to meet chemical composition specifications. (Melting/Melt Control) Basic knowledge in melt control with no equipment for it. Basic knowledge in metal composition and melt control, with minimal equipment for it. Advanced knowledge in metal composition and melt control with sophisticated equipment for it. Knowledge (K) (potential) (40%) Experience (E) (actual) (60%) Low (49 points) Medium (74 points) High (99 points) Factor (K/E = 40/60) Less than 1 year of experience in melt control, or rejection rate due to off-composition metal is ≥10% More than 1 year, but less than 5 years, experience in melt control with rejection rate due to off- composition metal is less than 10%. More than 5 years experience in melt control, or rejection rate due to off-composition metal is ≤3%. C. In an enterprise, the measurement of performance is at the end of the process, at the customer level, and may be external to the enterprise. PERFORMANCE CRITERIA A. Performance criteria are: 1. Specific statements to illustrate degrees of performance. 2. They should be: S-- pecific M -- measurable A -- ttainable R -- eliable T -- ime-bound 3. The performance level at each criterion is checked by raters. B. Steps in developing performance criteria: 1. Identify relevant performance measures. Each measure or criterion may be divided further into sub-criteria if necessary. 2. Write statements for each performance measure illustrative of various degrees of performance. 3. In a group consensus, agree on which performance measure each criterion most clearly refers to. 4. Decide on a scale of values for the selected criteria. 5. Arrange the criteria on the scales according to appropriate scale values and performance measures. 6. Review the final scale. C. Sample Performance Criteria (with tables below you can make your own criteria.) his paper has been prepared in order to better assess the performance of a foundry in its mandated objective of producing good quality and cost-effective metal castings. It provides the guidelines and a model for the preparation of criteria for measurement and how these can be applied. It can be best used after upgrading foundry performance based on the results of the measurement of foundry capability. Of course, it can be used in order to find out how an existing foundry operation is doing. 64 www.metals.rala.com.au
