Elements and Performance Criteria

1. Collect and collate all available data
   • Collate data on system performance
   • Collate data on environmental and workplace health and safety issues
   • Collate data on equipment supply and usage
   • Collate data on crop production
   • Collate data on water use and quality
   • Collate data on climatic trends
   • Collate data on physical and chemical properties of soil
2. Assess actual data against benchmarks, specifications and predictions
   • Analyse system performance and compare with system specifications and performance predictions
   • Analyse supply and stock use and compare with previous and estimated usage and costs
   • Analyse crop production and compare with previous and predicted production
   • Analyse water usage and quality and compare with past and predicted usage and quality
   • Analyse climatic information and compare with predicted trends
   • Analyse soil properties and compare with previous and predicted properties
   • Analyse production costs related to irrigation system and compare with previous and predicted costs
   • Analyse net profits and compare with past and predicted profits
3. Compile a report of system evaluation
   • Examine indicators of good performance
   • Examine indicators of poor performance
   • Examine causes of deviations from performance specifications and requirements
   • Prepare a report that includes discussion of results of data analysis and conclusions reached on irrigation system performance in relation to crop production and business performance
4. Recommend alterations to achieve performance improvement
   • Make recommendations to modify or eliminate causes of poor performance, or to enhance current performance
