Q

Functional View vs Process View

A

A common way to decompose a company is to divide it hierarchically into functional departments (e.g., sales and production)

Process: (spanning several functions)

(Internal/external request)
1. Input
2. Activities - adding value
3. Output
(Delivery of product/service)

Process view focuses on what we are in business to do from our customer’s perspective

Q

Business Process Model - Swimlane

A

A ‘row’ of tasks that are conducted by one actor; a boundary is shown
for each swimlane to distinguish the work of one actor from that
conducted by another actor. Where a task is completed by two actors
together, for example, where a hotel booking is made by telephone, a
task should be shown straddling both swimlanes

Q

Business Process Flow - Decision

A

A diamond-shaped box that represents the application of a business
rule in order to determine the next task to be performed. Each
process flow emerging from a decision point is clarified using a ‘guard
expression’, which is shown in square brackets. The guard expression
represents the business rule that determines whether or not the
process can progress in a particular direction of flow. There may be
several flows emerging from a ‘decision diamond’, each of which has a
guard expression stating the rule that has to be satisfied

Q

What is a class model?

A

Conceptual model of the data that needs to be held

17
Q

Components of a class model

A

CALM

Classes (datagroups)
- Things/Events/Places/People & Organisaions
Attributes (information to be held of the classes)
Logical Associations (between classes)
Multiplicities (How many instances one class can be associated with in another class
- Read “Each ‘class’ is associated with #..’ of the ‘other class’”
(5. operations)

18
Q

What does a class model not consider?

A

Technology/Processes/Constraints (i.e time)

It is conceptual

19
Q

How is a class represented in a class model?

A

A simple rectangle with the name of the class in the top compartment

Always written as a noun phrase i.e. Customer / BankAccount (Camel case)

20
Q

What does an association represent in a class model?

A

A logical/meaningful correspondence between classes

e.g. Customer MAKES booking
Passenger TRAVELS on train

21
Q

How is an association represented in a class model?

A

A line between classes with an arrow showing how it should be read with multiplicities. It may be labelled with a meaningful description i.e. Owns vs Owned by

22
Q

Why model data?

A

A data model allows the stakeholders who use the system, or obtain information from
it, to agree the data that is to be recorded and accessed.

Helps understand the business rules in relation to data and helps identify data requirements

23
Q

COTS advantages

A

Less expensive
Faster Implementation
Standard support 7 maintenance means a dedicated in house team is not required
COTS vendors keep their software up to date

24
Q

COTS disadvantages

A

Unlikely to be a perfect fit with requirements (process changes needed or pay for customisation)
No competitive advantage (all competitors can have the same)

25
Q

Bespoke software advantages

A

Meets business requirements
Ownership of development roadmap (control development and pace)
Aligns to business processes (no need to make changes)
Aids morale
Can be integrated with other systems
Differentiates from our competitors

26
Q

Bespoke software disadvantages

A

Expensive (cost and time)
Stakeholder management
Upfront investment
COTS may have features we have not considered

27
Q

Waterfall model

A

Development shown through a series of sequential steps. Each stage is reviewed and signed off before the next begins

28
Q

Waterfall Model - steps

A

Feasibility study - BC gateway before resources committed
Requirements analysis and specification - BC gateway confirmed after req
Solution design - BC gateway confirmed when estimate dev costs
Solution development & implementation - BC revisited before deployment
Operation of new processes and systems - benefits realisation is checked

29
Q

Waterfall Lifecycle

A

Feasibility study
Analysis
Design
Development
Testing
Implementation

30
Q

Agile

A

Delivered into iterations
User stories into product backlog and developed overtime
iterative development & incremental delivery

31
Q

Agile Manifesto

A

Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the
left more.

32
Q

What is V Model an extension of?

A

The waterfall model

33
Q

V Model

A

Relationship between each stage of the development cycle and the testing cycle

Business Case - Benefits Realisation
Business Requirements - Acceptance Testing
System Design - System Testing
Develop Modules- Unit Testing
Build/ Develop Solution

Not executed but planned i.e. write acceptance criteria/test scripts
