4 DATA QUALITY REQUIREMENTS 4.1 DATA QUALITY 4.1.1 Consistency In addition to the consideration of what waste statistics are required, the issue of data quality is equally vital. The main data quality requirements are: • consistency; • auditability / traceability / integrity; • timeliness; and • minimal paperwork. These criteria are discussed briefly below. The value of undertaking an extensive data collection process is limited if the data collected are not collated in a consistent manner. It is vital to ensure that common rules apply to all data gathering activities. Small variations in the methodology adopted for gathering and recording data can make significant differences to the figures presented, so it is crucial that data are collected on a consistent basis across each authority (i.e. all District Council operations) to enable meaningful comparisons and trend tracking. District Councils should thus ensure that the procedures developed for data monitoring are fully adopted and maintained. This issue further reinforces the need for a Data Reporting Officer (as described in Section 3.3) with sufficient authority to implement and enforce adequate monitoring and reporting systems. 4.1.2 Auditability / traceability / integrity An auditable data recording and monitoring system is essential to demonstrate the authenticity of the data and KPIs calculated from the datasets. The most practical way of achieving this is to document the procedures that are adopted in data gathering and to ensure that the documented procedures are deployed in the actual data gathering and collation processes. The use of simple step-by-step procedures will provide an auditable trail of data and also enhance the identification and resolution of data errors whenever they occur. In particular, it is essential that District Councils are able to provide demonstrable evidence of the quantities and fate of materials collected forrecycled and composting. District Councils will be required to verify and document the recycling / composting / reprocessing activities of their operators and recycling merchants and thus ascertain the actual percentages of input waste that is recycled/composted/reprocessed/disposed of and their end markets.

4.1.3 Timeliness Once a database has been developed for storing data, it is important that the required data input is carried out in a timely manner. Data from daily/ weekly / monthly operations should be fed into the database as soon as the information is generated, to keep the database up to date. Reporting outputs generated from the database can only be as current as the information that has be fed into the system, and late data entries will inevitably result in inaccurate reporting. 4.1.4 Minimal Paperwork District Councils are required to report data for several activities. These reporting tasks can be quite burdensome and as such the objective should be to keep paperwork down to a minimum. The issue of paperwork is also linked to the consideration of consistency, which is likely to suffer when the same data is collected more than once. Internal recording and monitoring systems developed by the District Councils should thus be designed to not only minimise paperwork, but also to enable the production of reports from a common database as far as practicable.
