Clear instructions must be available concerning the information that is needed and the format in which it is to be collected. Misunderstood instructions can result in lost time or erroneous decisions based on poor data. The responsibility for collecting and compiling data is assigned to a specific individual or section. If too many people work with the data, the likelihood of misunderstood instructions, errors, or inconsistent or inaccurate data increases. The method used to compile and organize the data depends on available data resources and the desired results.
Computer technology helps.
It can easily provide the statistical analysis needed to produce pertinent information. For instance, computers, sorting reports of crime by day of the week and hour of the day, can make comparisons readily available. Specific types of information may be requested. Reports can be obtained that reflect increasing and decreasing trends. Raw data must be organized and summarized before it will become meaningful for planning purposes.
