If it is possible to pre-print any information known about the client on a form, this will help reduce the amount of handwriting needed. Clear writing can also be encouraged by printing forms with 'guide lines' that are designed to make users write each letter or number in a separate box on the form. To minimise the difficulty in reading handwriting, persons completing forms can be encouraged to write clearly in capital letters in blue or black ink. Handwritten forms are probably the most liable to error, as handwriting can often be hard to read or decipher. Some forms of data capture are more reliable than others. Data can be captured in a variety of ways: on a paper form (which could be handwritten, marked with computer readable marks or typed), by telephone (after which the data is usually written down or typed into a computer by an operator), by face to face inquiry (when the data may again be written down or typed into a computer by a staff member), by clients directly entering data by on the internet or an 'electronic kiosk' (using 'on line' electronic forms), by an electronic voting device, and so on. The next step to consider is the method by which data is 'captured' from the source.
The most accurate election results data will be obtained directly from the officers in charge of counting centres, and not from media reports, election observers or political parties. For example, personal elector details will be more accurate if obtained directly from the electors themselves, and not from indirect sources such as acquaintances or other organisations' databases of questionable quality. This means that data will be legally obtained from reliable sources, preferably 'primary' sources rather than 'secondary' sources. The first step is to use reliable collection methods. There are several measures that can be taken to ensure the reliability of data used in electoral computer systems. A computer system that relies on data is only as good as the data it contains. Ensuring the reliability of data is crucially important.
Electoral rolls of voters, electronic voting systems, election results systems and staff and materials databases are all based primarily on data. Many electoral computer systems exist primarily to store and make use of data.
