The detailed advice for analysts is provided as four TAG units:
- VDM Preliminary Assessment Procedures (TAG Unit 3.10.1) that defines criteria to enable analysts to decide whether the effects of variable demand seriously undermine the justification for their scheme;
- VDM Scope of the Model (TAG Unit 3.10.2) gives the guidance required to specify the scope of a variable demand model;
- the form of variable demand mechanisms and the circumstances when they are suitable to be used are described in VDM Key Processes (TAG Unit 3.10.3);
- VDM Convergence Realism and Sensitivity (TAG Unit 3.10.4) sets out appropriate convergence standards together with the required realism and sensitivity tests needed to provide evidence about the robustness of the model
