Presentation Transcript

  1. Quality Exercise Instructions • Quality Analysis • It is approximately 6 months after the JTAMS Increment 1 CDR. Your team in the JTAMS program office has received a set of slides from Juggernaut depicting the current status of the overall JTAMS development. • The PM believes that something is amiss and has asked your IPT to perform an in-depth analysis to assess the program’s status from a quality perspective. The PM had previously identified the program’s specific Quality Attributes and is concerned that the data does not allow for a good quality assessment. The PM wants your IPT to complete the enclosed assessment templates. • Tasks:  Within your IPT, review carefully the set of charts to identify problems, assess their impact, project the outcomes, and evaluate alternatives. • Does the data provided meet information needs based on the PM’s Quality Attributes – (see slide 2)? If not, identify additional data required to support the PM’s Quality Attributes. Include Indicators and Measures recommendations (Use the ICM Table). Each Team will select the attribute that corresponds with their Team number. (i.e. Team 1 = Attribute 1 (Interoperability), etc ) • Does the data provided meet the information needs based on your teams assigned ISO 25010 Quality Model Characteristic – (see slide 6)? If not, identify additional data required to support your assigned ISO 25010 Quality Model Characteristic and indicate how leveraging these characteristics can lead to improved quality for JTAMS - Include Indicators and Measures recommendations (Use the ICM Table). • Identify recommendations to the PM based on the insight gained from your analysis of Tasks 1 and 2

  2. PM JTAMS Quality Attributes 4. Quality Attribute: Modularity Attribute Concerns A. Replace an architectural component Loose coupling/high cohesion Design from a common set of components 1. Quality Attribute: Interoperability Attribute Concerns A. Ease of interfacing with using applications B. Ease of interfacing with other systems 2. Quality Attribute: Adaptability Attribute Concerns Ability to accommodate new requirements Ability to accommodate new technologies Ability to field a subset of the current requirements (functionality) Ability to support various platforms 5. Quality Attribute: Usability Attribute Concerns A. Minimize user training (operator, user, non-signal user) B. Enable user to perform tasks in allocated time. C. Minimize number of operators. D. Consistent GUI (common look and feel) 3. Quality Attribute: Maintainability Attribute Concerns A. Ability to accommodate new technologies B. Ability to support isolation of faults C. Minimize training for maintainers
