The following phases can be distinguished when constructing a new model and the accompanying questionnaire:
Phase 1: Determining and defining concepts, indicators and factors
Which indicators should be included in the questionnaire is determined in collaboration with the various parties concerned. The selected indicators are then further divided into various factors.
Phase 2: Desk research
The selected concepts and relevant indicators and factors are then worked out in depth and put through specialised literature. Interviews with key players in the various parties concerned can also be carried out in this phase.
Phase 3: Determining test items
In the third phase, test items are selected and a questionnaire drawn up. For each of the factors, more items are sought out that can measure the indicators in a reliable and valid manner. ZebraZone items are usually given a score on a six-point scale. However, this can be adjusted depending on specific needs. In this phase, the contents of the questionnaire are very broad.
Phase 4: Pilot project
The questionnaire is tested during this phase using a random sample within the branch. On the basis of these data, a selection is made in the following phase of items which can provide a constructive contribution to the final model. At the end of this phase, a pre-final version of the model and of the questionnaire is obtained for model measurement purposes.
Phase 5: Statistical analysis of test items and construction of a valid model
In the last phase, the pre-final version of the model is subjected to an in-depth statistical analysis in various stages. This iterative process (Phases 4 and 5) is repeated until the model meets the determined statistical criteria.
The whole project may take a number of months to complete.
