3. -2- Problem Frames Problem Frames – brief description Fundamental Philosophy –Problem analysis or the Problem Frames approach is an approach to be used when gathering requirements and creating specifications for computer software (http://en.wikipedia.org/wiki/Problem_Frames_Approach) Brief Description of HMC project, Stargate. –A xDB converter is to convert Point Of Interest (POI) data to the output format (xDB) which can be used in HMC navigation system. Considering questions for focusing on the problem –Is all data (POI) available for converting? –Can HMC change the rule? –Is data format flexible?
