Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ballpark approximations and past experiences are used for effort estimation, then the estimation process is simple and quick, but the accuracy of the estimate deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically generating UI prototypes and visualizing the target system during the estimation phase. This allows accurate effort estimation to be conducted before detailed design begins, eliminating the need for rough approximations while maintaining quick estimation through automation.
Solution Approach 2:
The patent replaces the mechanical system of manual expert assessment with an automated computer-based system that generates UI prototypes and calculates effort estimates algorithmically. This substitution maintains high productivity through automation while improving accuracy by eliminating human bias and inconsistency.
2Device complexity
If expert opinions and past experiences are relied upon for estimation, then the estimation process requires minimal visualization, but the reliability of the estimate deteriorates due to lack of objective basis
Solution Approach 1:
The system creates preliminary visual representations of the UI during the estimation phase itself, rather than requiring detailed visualization later. This preliminary action provides an objective basis for estimation while keeping the overall process relatively simple.
Solution Approach 2:
The patent introduces an intermediary automated system that acts as a mediator between requirements and effort estimation. This intermediary generates standardized UI prototypes and applies consistent estimation algorithms, providing objective reliability without requiring complex manual visualization processes.
3Measurement precision
If detailed UI screens are developed before estimation, then the estimation accuracy improves, but the time and cost required before project initiation increases
Solution Approach 1:
The system performs preliminary UI prototyping and effort estimation in parallel during the early project phase, rather than sequentially. This allows accurate estimation to be achieved without requiring complete UI development beforehand, reducing time loss while maintaining precision.
Solution Approach 2:
The patent applies partial action by creating simplified but sufficient UI prototypes that are adequate for estimation purposes, rather than developing complete detailed screens. This partial prototyping provides enough information for accurate estimation while minimizing the time and resources required before project initiation.
4Device complexity
If manual expert assessment is used for effort estimation, then the system complexity remains low, but the productivity of the estimation process deteriorates due to lack of automation
Solution Approach 1:
The patent replaces manual expert assessment with an automated computer-based system that generates UI prototypes and calculates effort estimates. This substitution dramatically improves productivity through automation while keeping system complexity manageable by using standardized algorithms and templates.
Solution Approach 2:
The system performs self-service by automatically generating UI prototypes and calculating effort estimates without requiring manual intervention from experts. This automation improves productivity significantly while maintaining relatively low system complexity through rule-based algorithms.
