Question Answer
What does a sequence diagram show? The order of which system events occur
What does an activity diagram show? Shows temporal dependencies, much like a flowchart
What does a collaboration/communication diagram show? The order in which classes communicate to each other. It shows control flows with arrows
What does a class diagram show? The classes of the system and the relationship between these
What are open source projects? Software/projects that are available for modification by anyone
What three issues could occur from open source development via web only? Unreliable - no clear-cut discipline Irregular quality and/or updates Not designed for user well
What two documentation and version issues could occur from open source situations? Many people developing - more people to consult changes with Testing may not be completed correctly
What is Abbott analysis? The process of describing system functionality then highlighting nouns and verbs in them.
What are nouns equal to for Abbott analysis? Candidate objects. Nouns describe; people, animal, place, thing and idea
What are verbs equal to for Abbott analysis? Operations upon the candidate objects. Verbs describe a doing action
Name two advantages of Abbott analysis Simple Forces use of problem domain language Encourages inclusion of all possibilities Can be partially automated
Name two disadvantages of Abbott analysis English is imprecise - different terms for same abstraction Dependent on complete description Verbs can become nouns and nouns written as verbs
In a class diagram what does a dashed line show? It shows association with another object between the two class relationships
How can you represent parameters in a class diagram? You can use a dotted box to the top right with the parameter letter or use a <CLASS> notation

What are the 6 steps for feasibility analysis? 1. Understand the problem or opportunity 2. Define scope or constraints 3. Fact finding 4. Analyse the data 5. Feasibility evaluation 6. Present the results
What is technical feasibility evaluation? The evaluation of technical resources and expertise for building, integrating and maintaining the proposed system
What is schedule feasibility evaluation? The evaluation of the staff and stakeholders with regard to availability, budget and time
What is operational feasibility evaluation? The evaluation of the proposed system being effective, impact on staff, adverse user effects, negatives and positives
What is economic feasibility evaluation? The evaluation of costs for development, annual operating, annual benefits and intangible costs and benefits. The evaluation of cost benefit analysis
What are the three types of cost benefit analysis? Payback analysis Return on investment analysis Present value analysis
What is the purpose of payback analysis? To generate a payback period when the initial and annual costs are overtaken by benefits
What is the purpose of return on investment analysis? To calculate the percentage return on investment for N years
What is the purpose of present value analysis? To compare the cost and benefits of the project against the rate at which money invested accrues value
What does RUP stand for? Rational Unified Process
In RUP what is initially identified? Workflows - identified by each team member, the activities they perform and the artifacts they produce
Name the 5 phases of the RUP iteration Planning, analysis, design, implementation and testing
Name two disadvantages of RUP Requires more active management and sense of direction for project Needs to be customised to size of team Can overload workforce
What 4 things are well defined in each RUP phase? Aims, activities, inputs and products
What are the 4 product types for RUP? Inception, elaboration, construction and transition
For an inception product type what is the main task? Making business case for justification of project
For an elaboration product type what is the main task? Building the architectural baseline to guide the future work
For a construction product type what is the main task? Producing a beta version of the software
For a transition product type what is the main task? Establishing product in operation environment and monitoring feedback. Fixing minor defects in beta and regression testing
What are the 4 phases of RAD methodology? Requirements planning, user design, construction and cutover
What does RAD stand for? Rapid Application Development
In RAD, what happens in the requirements planning stage? Stakeholders decide on scope and system requirements
In RAD, what happens in the user design stage? Users help develop working model via prototype
In RAD, what happens in the construction stage? Further programming, testing, still with users
In RAD, what happens in the cutover stage? System testing and user training
Name 2 reasons why the quality of requirements is important - Assessing successful product - Assessing if can produce product - Prevents parts being missed out or added or confused with what the user wanted - Prevents failure of not achieving what was necessary
Name 4 keywords that requirements must be Unambiguous, complete, correct, understandable, verifiable, consistent, achievable, design independent, traceable detailed (appropriately)
Name two of the original use cases for the Stroke Therapy application? - Select menu item - Enter words to speak - Begin playback of user input - Stop playback of user input - Select word to practice handwriting - Practice handwriting - Stop current word practice and return to list of words - Play sequence jumble game - Stop current sequence game - Play sentence completion game - Stop current sentence completion game - Show event list - Add events - Edit events - Delete events - Change settings
Name the 5 schools of Pettichord testing Analytic, Routine, Quality, Context driven, Agile
Name 2 of the ISO-9126 standards (Hint they start with: F, R, U, E, M, P) Functionality, reliability, usability, efficiency, maintainability, portability
Apart from Compliance, name the 4 subcategories of the Functionality ISO-9126 standard (Hint they start with: S, A, I, S) Suitability, accuracy, interoperability, security
Name the 3 subcategories of the Reliability ISO-9126 standard (Hint they start with: M, R, F) Maturity, Recoverability, Fault tolerance
Name the 3 subcategories of the Usability ISO-9126 standard (Hint they start with: L, U, O) Learnability, understandability, operability
Name the 4 subcategories of the Maintainability ISO-9126 standard (Hint they start with: S, A, C, T) Stability, analyzability, changeability, testingability
In Pettichord testing, what is analytic testing? Testing is mathematical and technical with 1 right answer. Require precise specs, most used in high-reliability industry
In Pettichord testing, what is routine testing? Testing validates the product, measures progress and can be done with cheap labour. Poor at change handling, but most used for IT projects
In Pettichord testing, what is quality testing? Testing maintains quality by policing developers and ensuring discipline. Tends to alienate developers in most large project
In Pettichord testing, what is context driven testing? Testing finds anything that bugs a user. A skilled activity that adapts to change and developers testers abilities to design tests, most used in market-driven development
In Pettichord testing, what is agile testing? Emphases on automated testing and proving development complete
In business, what is a strategic plan? What the company is doing and aims to do in the future. Analyse whether the software fits in with these goals
What is an interaction diagram? Normally use cases, but can be sequence or communication depending on preference and focus of interest
Pitts & Browne suggest what 4 things to overcome requirements capture? - Summarisation and feedback - Repetition and rephrasing - Scenario building and elaboration - Counterargument
What is a functional requirement? A requirement that describes what the system must do
What is a non-functional requirement? A requirement that describes how the system works
What do we estimating at the start of a project? - Effort - how many staff and for how long? - Elapsed time - how long from start to finish? - Risk - Size - how much documentation/software required? -Speed - of the system -Reliability - how often will it break down?
Name an advantage of RUP Reactive and responsive when changes or snags occur Allows for small features to be added in as going along
Name 3 criteria used to reject classes (Hint: 'How to Zap Classes' lecture 8 slide 12, Begin with: M,E,M,O,I,R,A,V) - Redundant (2 names meaning the same thing) - Vague (e.g. system) - Event or operation (but check for state, behaviour, identity e.g. takeoff, explosion) - Meta-language (tool of our method, not object within it e.g. noun or object) - Outside scope (e.g. week) - Attributes (e.g. address) - Methods (e.g. Encryption) - Too implementational (e.g. index)
Explain 1 method (other than Abbott analysis) that you could use to identify the objects for a problem - Domain analysis - Classical categorisation - Conceptual clustering - Prototype theory
What is domain analysis? Find classes and objects that are common to all applications within a given domain. Vertical = across similar applications Horizontal = related parts of the same application
What is classical categorisation analysis? All entities with a given property or set of properties in common form a category
What is conceptual clustering analysis? Start from a concept, consider individual parts of it and then add to a set
What is prototype theory analysis? Start from a prototypical object to define a class and test a new potential class member against this test
