The Nature of Software

Intangible



Easy to Reproduce


Opposite of physical artifacts. E.g. Computer vs
Windows XP, IPod vs ITunes.
Hard to understand the development process.
Costly design and construction, cheap
manufacturing.
Malleable


4/13/2015
Easy to change, even without full understanding.
Untrained people can “hack” something together.

Quality of Good Software

Usability


Efficiency


Reliable, secure and safe
Maintainability


Does not waste resources such as CPU time and memory
Dependability


Easy to learn and use
Easily evolved (modified) to meet changing requirement
Reusability

4/13/2015
Parts can be reused, with minor or no modification

Software Development Problems

“Software is not constrained by materials, or
governed by physical laws, or by
manufacturing process” ---- (Sommerville
Software Engineering).

Allows almost unbounded complexity

4/13/2015
Exponential growth of complexity w.r.t the size of
a program: twice the size, four times the
complexity.

Software Development Problems

Difficulty in understanding and managing the
complexity causes:

Late completion:


Overrunning Cost:





“vaporware” that are announced but never produced
Denver Airport Automated Baggage System, 2 billions
US dollar over budget
Unreliable
Difficult to maintain
Etc…

Software Engineering is
IEEE Standard 610.12:
 The application of a systematic, disciplined,
quantifiable approach to the development,
operation, and maintenance of software,
that is, the application of engineering to
software.

The study of approaches as in (1)

Software Process


The set of activities and associated results
that produce a software product.
Four fundamental process activities:





Software Specification
Software Development
Software Validation
Software Evolution
Can be organized in different ways, described
at varying level of details → different software
development process models.

Software Process Stages
Requirement
Specification
Analysis
Development
Design
Validation
Implement
Test

Evolution
The mapping between the common development
stages with the four general process stages.

Unified Process

State of the art process, by learning from the history
of software development process.

Phases in Unified Process




Inception:
 Define the scope of the project and develop business case
 Concentrate on Business Modeling and Requirement Gathering
Elaboration:
 Plan project, specify features, and baseline the architecture
 Concentrate on Analysis and Design
Construction:

Build the product
 Concentrate on Implementation and Testing
Transition:
 Transfer the product to its users
 Concentrate on Deployment

Iterations within Phase

Each iteration within the phase passes through all the
workflow (activities):



Requirement, Analysis, Design, Implementation, Test
With different emphasis on the workflow activity according to
the phase.
Each iteration should result in a executable release


4/13/2015
Special Case:
 In the Inception Phase, a single release is usually
produced at the end of the Phase instead of each iteration
Early releases serve as prototype which provide feedback to
later iterations.
CPSC-4360-01, CPSC-5360-01, Lecture 14
13
Unified Process and UML

UP is Use Case Driven:



A systematic utilization of Use Case
UML diagrams are used in the Requirement,
Analysis and Design activities in the UP
workflow.
Because of their history, there is a close fit
between UML and the UP.
