obstacle categories and prevention obstacle diagrams and obstacle identification

Discussion 1

Obstacle Categories and Prevention” Please respond to the following:

Suppose that you are performing an obstacle analysis of the software that you developed for the self-parking car discussed previously. Determine which of the following obstacle categories you would apply during the analysis: hazard obstacles, threat obstacles, dissatisfaction obstacles, misinformation obstacles, inaccuracy obstacles, and usability obstacles. Defend the selected category that you selected with two examples.
The alternative techniques for obstacle prevention are goal weakening, obstacle reduction, goal restoration, obstacle mitigation, and doing nothing. Examine the alternative techniques and select the one that you would use for obstacle presentation. Defend your selection

Obstacle Diagrams and Obstacle Identification” Please respond to the following:

From the e-Activity, determine any similarities or dissimilarities between the goal model diagrams and obstacles diagrams.
Provide one example of when you would use the tautology-based refinement technique. Provide one example of when you would use the obstructed target technique. Defend why you chose to use each technique in the examples that you did.
