Rand Water - Background
• So who is Rand Water exactly?
• What do they do?
• Who are the customers?
• What area is covered?
• Where does the water come from?
Rand Water – Background contd..
• How is the water treated?
• What about during the pumping process?
• How often are samples taken?
• Are there standards that you adhere to?

Chlorophyll-α and Chlorophyll-665
• Significance of the Chlorophyll analysis
• Algal related water problems : Algae interferes with the purification process• Algae interferes with the purification process
• Algae results in water with bad taste, odour and colour• Trihalomethane pre-cursor and source of carbon forTrihalomethane pre cursor and source of carbon for
microbiological growth

Process Followed
• Compilation of URD’s
• System development
• Testing and training
• Rollout to production

Challenges
• Interfacing instruments
• Design – multiple options during brainstorming
• Linking reference monthly QC’s to daily batches
• Viewing of multiple components in a chart
Challenges
• Pipettes
• The design of specification limits for pipettes had to accommodate the following requirements
• Pipettes are method specific
• Pipettes are categorised by volume
• Each pipette has limits for 10%, 50% and 100% of its capacity
PTS and IAC• PTS = Proficiency Testing Scheme
• IAC = Inter-Analyst CompetencyIAC Inter Analyst Competency
• Rand Water runs the PTS (and internal IAC) for Chlorophyll-α and Chlorophyll 665

Benefits Realised• Ensuring QC’s done and comply to Quality manual – Stops
the process until all pre-requisites are completed
• Reduced amount of time spent on data entry
• Higher accuracy of data – finger faults eliminatedHigher accuracy of data finger faults eliminated
• All necessary QC’s included in the batch
• Flagging out-of-spec data
• Free up analysts to perform other lab tasksp y p

Lessons Learned
• Thorough analysis of requirements before design is critical
• Design improved with every method implemented
• Thorough analysis and design improves• Thorough analysis and design improves
ease of use of solution for user
maintenance in future

The Way Forward
• Continuous improvement of analysis and design t h itechniques
• Implement using built-in LabWare functionality or modules h iblwhere possible
• Accept that, sometimes (often, actually), LIMS Basic d l t i i it bl d t i b i ldevelopment is inevitable due to unique business rules
• Implement Plate Manager module and Enhanced Visual Workflows
