Web-based data collection, as implemented by Macro, provides several key advantages:

• All entered data are stored in and retrieved directly from centrally located database records. Respondents can provide requested data over a number of sessions and, at the beginning of each session, find their submissions exactly as they were at the end of the previous session. Data that are available prior to collection can be preloaded; the individual respondents do not have to re-enter them each year.
• All data are immediately validated for completeness and consistency as they are entered. Such data quality control measures are far more effective when done during data entry and result in much higher quality data. Easy-to-understand symbols and messages help the user ensure that each response is complete and accurate.
• The status of the data collection effort can be monitored in real time. At any point during data collection, Macro and the client can check how many respondents are in the process of completing the questionnaires and how many have completed their responses. Preliminary summaries of provided data can be produced well before the data collection due date. Such "distance monitoring" is invaluable in ensuring timely and accurate data collection.
• Data analysis can begin immediately after survey closeout. Report on key indicators can be produced while the survey is in the field so that preliminary data analysis can begin at any time during data collection.

The benefits of Web surveys go beyond data entry. Web system features permit tracking data, response progress, and trends. Each Web survey we develop includes a monitoring system for use by survey managers, survey project officers, and survey contractors. This system includes monitoring, administrative, and report functionality. Any function of the monitoring system can be reached by clicking on the appropriate link.
