Analyzing Quantitative Documents
Many quantitative documents are available for interpretation in any business, and they include reports used for decision making, performance reports, records, and a variety of forms. All these documents have a specific purpose and audience for which they are targeted.

REPORTS USED FOR DECISION MAKING. A systems analyst needs to obtain some of the documents that are used in running the business. These documents are often paper reports regarding the status of inventory, sales, or production. Many of these reports are not complex, but they serve mainly as feedback for quick action. For example, a sales report may summarize the amount sold and the type of sales. In addition, sales reports might include graphical output comparing revenue and income over a set number of periods. Such reports enable the decision maker to spot trends easily. Production reports include recent costs, current inventory, recent labor, and plant information. Beyond these key reports, many summary reports are used by decision makers to provide background information, spot exceptions to normal occurrences, and afford strategic overviews of organizational plans.

PERFORMANCE REPORTS. Most performance reports take on the general form of actual versus intended performance. One important function of performance reports is to assess the size of the gap between actual and intended performance. It is also important to be able to determine if that gap is widening or narrowing as an overall trend in whatever performance is being measured. Figure 5.3 shows a clear improvement in sales performance over two to three months. The analyst will want to note if performance measurement is available and adequate for key organizational areas.

RECORDS. Records provide periodic updates of what is occurring in the business. If the record is updated in a timely fashion by a careful recorder, it can provide much useful information to the analyst. Figure 5.4 is a manually completed payment record for an apartment rental. There are several ways that the analyst can inspect a record, many of which are indicative of their usability:
1. Checking for errors in amounts and totals.
2. Looking for opportunities for improving the recording form design.
3. Observing the number and type of transactions.
4. Watching for instances in which the computer can simplify the work (i.e., calculations and other data manipulation).

DATA CAPTURE FORMS. Before you set out to change the information flows in the organization, you need to be able to understand the system that is currently in place. You or one of your team

members may want to collect and catalog a blank copy of each form (official or unofficial) that is in use. (Sometimes businesses have a person already charged with forms management, who would be your first source for forms in use.) Blank forms, along with their instructions for completion and distribution, can be compared with filled-in forms to see if any data items are consistently left blank on the forms; whether the people who are supposed to receive the forms actually do get them; and if they follow standard procedures for using, storing, and discarding them. Remember to print out any Web-based forms that require users to print them. Alternatively, electronic versions that can be submitted via the Web or email can be identified and stored in a database for later inspection. To proceed when creating a catalog of forms to help you understand the information flow currently in use in the business:
  1. Collect examples of all the forms in use, whether officially sanctioned by the business or not (official versus bootleg forms).
  2. Note the type of form (whether printed in-house, handwritten, computer-generated inhouse, online forms,Web fill-in forms, printed externally and purchased, etc.).
  3. Document the intended distribution pattern.
  4. Compare the intended distribution pattern with who actually receives the form.

Although this procedure is time consuming, it is useful. Another approach is to sample data capture forms that have already been completed. Remember to check databases that store consumer data when sampling input from ecommerce transactions. The analyst must keep in mind



many particular questions, as illustrated in Figure 5.5. They include the following aspects of HCI relating to usability, aesthetics, and usefulness:
  1.  Is the form filled out in its entirety? If not, what items have been omitted, and are they consistently omitted? Why?
  2.  Are there forms that are never used? Why? (Check the design and appropriateness of each form for its purported function.)
  3. Are all copies of forms circulated to the proper people or filed appropriately? If not, why not? Can people who must access online forms do so?
  4.  If there is a paper form that is offered as an alternative to a Web-based form, compare the completion rates for both.
  5. Are “unofficial” forms being used on a regular basis? (Their use might indicate a problemin standard procedures or may indicate political battles in the organization.)
