PERFORMANCE CRITERIA |
1. Collect and collate all available data |
1.1. Data on system performance is collated. 1.2. Data on environmental and Occupational Health and Safety (OHS) issues is collated. 1.3. Data on equipment supply and usage is collated. 1.4. Data on crop production is collated. 1.5. Data on water use and quality is collated. 1.6. Data on climatic trends is collated. 1.7. Data on physical and chemical properties of soil is collated. |
2. Assess actual data against benchmarks, specifications and predictions |
2.1. System performance is compared to system specifications and performance predictions. 2.2. Supply and stock use is compared to previous and estimated usage and costs. 2.3. Crop production is compared to previous and predicted production. 2.4. Water usage and quality is compared to past and predicted usage and quality. 2.5. Climatic information is compared to predicted trends. 2.6. Soil properties are compared to previous and predicted properties. 2.7. Production costs related to irrigation system are compared to previous and predicted costs. 2.8. Net profits are compared to past and predicted profits. |
3. Compile a report of system evaluation |
3.1. Report includes discussion of results of data analysis. 3.2. Indicators of good performance are isolated and discussed. 3.3. Indicators of poor performance are isolated and discussed. 3.4. Causes of deviations from performance specifications and requirements are examined. 3.5. Conclusions about irrigation system performance in relation to crop production and business performance are clearly stated. 3.6. Conclusions are supported by the data. |
4. Recommend alterations to irrigation system to achieve performance improvement |
4.1. Recommendations are made to modify or eliminate causes of poor performance, or to enhance current performance. |
