Features — Project management

Quota managementunlimitedCallWeb supports completion quotas based on single-character stratification (e.g., gender) and multiple-character stratification (e.g., gender within age groups) as well as compound stratification (e.g., a set of quotas on gender and a set on age groups). Membership to a stratum can be based on pre-populated data as well as on data collected in the questionnaire itself and on a combination of such. Quota targets can be modified at any time during the data collection period. Once a quota is filled, respondents from that stratum are redirected within the questionnaire, for total control over the handling of the situation.
Maximum number of concurrent sessionshundreds,
according to the server
It is possible for a server to manage hundreds of concurrent data collection sessions. The limit is a function of the server power and of the amount of RAM available. The processing of a screen-worth of data is completed in a fraction of a second after which the contact between the server and the user is broken while the user reads the new information and records the answers. This leaves ample time to the server to deal with hundreds of other connections.
Complete questionnaire in HTML formatokA utility exists to produce an HTML version which details all elements of the questions and of the answers, including skips and display conditions for questions and response categories. This helps to ensure the integrity of the questionnaire before final production and to communicate the questionnaire in a user-friendly format. This HTML questionnaire can also report raw and percent distribution of responses for each question.
Complete questionnaire in RTF formatokA utility exists to produce an RTF version which details all elements of the questions and of the answers, including skips and display conditions for questions and response categories. This helps to communicate the questionnaire in a user-friendly format. This RTF questionnaire can also report raw and percent distribution of responses for each question.
Manual or automatic e-mail notifications and recuperation of bounce messagesokA specialized but integrated module sends initial notification and reminders via e-mail. It uses a text file template which may include recalls of values stored in the survey data base (probably via pre-population). It features tools to select subsets of cases according to any data in the data base as well as subsets defined by ranges of position numbers in the data set. Therefore, it is possible, for example, to send an initial invitation to all participants which includes their custom access code and which is delivered in their preferred language, and to follow-up with those who have initiated but not completed the questionnaire a week later with a motivational message which could be different from another follow-up to those who have not accessed the questionnaire at all.
 
These invitation and recall operations can be performed manually, under the direct control of an operator, or automatically, on the basis of selection and mailing rules. This way, a large portion of the contacts with participants (e.g., in the context of a panel study requiring strict management of contacts) can be automated, thereby avoiding human errors.
 
Moreover, another CallWeb module can intercept bounce messages and add an indication relative to that delivery error right into the CallWeb data base so that erroneous e-mail addresses can readily be researched and corrected.
Real time data editingokA tool is available to visualise the data base in whole or in part (e.g., certain answers and/or certain entries). If the user possesses the required access code, he or she can modify the data or delete entries.
Real time results presentation moduleokA module produces univariate and crosstab tables as well as graphs in real time. A client or an analyst is able to querry the data aase, obtain preliminary data, ensure the coherence of the information, etc. without resorting to a technician.
