Integrating Quality Control Measures
- I have an interesting design challenge and I wonder if others in the
group have addressed it. During our analysis and requirements
sessions, the issue of quality control has come up several times.
Namely, ensuring the accuracy of key information entered such as a
person's profile and address, dollar amounts and so forth.
Currently, the customer has a quality control team that reviews data
entry. They would like the new system to have quality control more
integrated and at the point of entry.
The one suggestion that keeps coming up is double-keying the key
information. Naturally, the idea of dual-entry, even for the purpose
of quality control, goes against the grain of a good designer.
So, does anyone have any other creative ideas for addressing this
Secondly, if re-keying is used, my instinct tells me that double-
keying a field in succession may be less effective than keying the
information in different parts of the flow. For example, if an entry
form had a field for a check amount, with the repeated check amount
immediatley following, it seems likely that the user would glance at
the check once and type the same (incorrect) amount in both fields.
However, if the re-keying were to happen later in the flow, the user
would look at the check a second time and be less likely to enter the
same incorrect number twice. Does anyone have any empirical evidence
to back-up my instinct, or is my instinct incorrect?
Thanks for your help.
