Flashcards do conjunto (22)
- 1Why is BA important in requirements engineering?Analyse, communicate and validate requirements for changes to busniess processes, policies and information systems
- 2Why are requirements difficult to elicit?Diffrent views depending on where you sit in an organisation
Little communication between sections - 3What are the consequences of these different viewpoints?Ambiguity and lack of clarity
Duplications and conflicts
Uncertainty, lack of specificity and omissions
Inconsistency and lack of common understanding - 4What are the 5 steps in requirement engineering?Elicitation: Gathering requirements from stakeholders
Analysis: Examine requirements looking for inconsistencies.
Validation: Requirements are checked and signed off
Documentation: Develop requirments doc
Management: Activities needed to manage changes to the requirements - 5Who are the principle actors in the requirements process?Project sponsors - accepts requirements/funds project
The domain expert - provides knowledge about processes
The business users - provide requirements & highlight difficulties
The project teams - schedule, deliver the project - 6How to start the elicitation process?-Study the organisation using website/documents
-Identify stakeholders - 7What are the 2 types of investigation techniques?Qualitative: understanding the context and details of the business situation. Can be individual or group related
Quantitative: collection of numerical data. Collected set of entities - 8Data types and analysis?Qualitative data produces textual data these are analysed using Textual analysis
Quantitative produces mathematical data these are analysed using Statistical analysis/Mathematical models - 9What are some Qualitative techniques?Interviews - focus on views of individual. Give info on weaknesses and what is needed
Observations - see how work is done
Prototyping - building models to analyse them
Focus Groups - small group of people to discuss topic - 10What are some Quantitative techniquesQuestionnaires - series of questions
Structured interviews - filled out when interview is present
Structured observations - measure observed activities
Special-purpose records - keeping log - 11What is Business Systems Integration?Combines both business integration & information systems integration
- 12What are the drivers for business system integration?Rise of the virtual organisations
Increasing service-oriented customer demands
Need a greater knowledge in providing good & services
Increasing complexity of products and systems
Rapid technological change - 13What is Business Integration(BI)?creation of tighter coordination among business activities conducted by different individuals or organizations so that a unified business process is formed.
- 14What is Internal business integration ?activities across various internal organisational units towards effecting a uniform business process
- 15What is External business integration ?activities between the organisation and its partners towards effecting a business process across organisational borders
- 16What would be a Internal BI example?Developing a new product for the market
Uses marketing - research on products, engineering - desgin prototypes and analysts - define pricing/feasibility - 17what would be a external BI example?Cisco and its suppliers form a tightly integrated order fulfilment process
Form a tightly intergrated Order fulfilment process - 18How is business integration achieved?BPR/BPI are methodologies for internal business integration
None for external integration - 19What is System Integration (SI)?The creation of tighter linkages between different computer-based information systems and databases
SI is often needed to achieve BI - 20Forms of System Integration?Data warehousing: extracts data from diffrent systems and stores into single repository
Integrated software systems: (ERP) applications from diffrent functions integrated into common database - 21Benefits of integrated ERP systems?A shared common database allows tighter integration and removes redundancies
- 22Problems of system integration?Dependency on legacy systems as they hold data which is crucial for day-to-day operations
Different operating systems/ programming styles
