Table 2 Distinctive features of the V-Model
Id | Distinctive features | Related issue | |
|---|---|---|---|
Representation | P1 | Connection of Problem-Action relationship (P-A connection) | Causality |
P2 | Non-explicit temporal expression (non-explicitness) | Granularity | |
P3 | Temporal proximity implied in medical terms (proximity hint) | Non-explicitness | |
P4 | Uneven granularity (uneven granularity) | Non-explicitness | |
P5 | Implicit internal sequence | Non-explicitness | |
Reasoning | R1 | Problem starts before Action (P precedes A) | Reasoning |
R2 | Qualitative temporal relation (qualitative relation) | Reasoning | |
R3 | Temporal distance from non-explicit event (implicit distance) | Reasoning | |
Visualization | V1 | Intuitive view in discovering Problem-Action relationship (intuitive P-A relation) | Visual enhancement |
V2 | Blocking effect of Problem-Action relationship among successive events (blocking effect) | Visual enhancement | |
V3 | Overview of events' flow | Visual enhancement | |
V4 | Dynamic scaled timeline (dynamic scale) | visual enhancement | |
V5 | Highly readable history view in tracing long period events (long history) | visual enhancement |
