PRESENTATION GOALS
 Define software engineering
 Show how an SDLC enables software
engineering
 Provide a tutorial on RUP
 It’s
a library of SDLC processes and
 A platform for delivering any SDLC

WHAT IS ENGINEERING?
 Engineering is the discipline, art and profession of
acquiring and applying technical, scientific, and
mathematical knowledge to design and implement
materials, structures, machines, devices, systems,
and processes that safely realize a desired
objective or invention(1).
 Key elements:
 Discipline
 Applying knowledge
 Realize objective

WHAT IS SOFTWARE ENGINEERING?
 Software engineering is the application of a
systematic, disciplined, quantifiable approach to the
development, operation, and maintenance of
software, and the study of these approaches; that
is, the application of engineering to software.(2)
 Key elements:

WHAT IS AN SDLC?
 The systems development lifecycle (SDLC) is a
type of methodology used to describe the process
for building information systems, intended to
develop information systems in a very deliberate,
structured and methodical way, reiterating each
stage of the life cycle.(3)
 Some examples:
 Waterfall
 Iterative
 Agile
 Extreme programming

CHOOSING THE RIGHT SDLC
Decision Factors:
• Team size
• Problem complexity
• Risk
• Competency levels
• Centralized vs.
dispersed
• Time to market
• Quality

11.
WHAT IS RUP?
 SDLC content templates
 Process authoring tool (RMC)
 Process delivery (web-site)
Note: Contrary to what many people
think, RUP does not include software
engineering tools. However, tools are
usually referenced where they are used
in the process. Therefore, RUP can be
used with any vendor’s tools.

12.
EVOLUTION OF RUP
 Need for a standard
methods framework
 Unified Method
Architecture (UMA)
 A process engineering meta-
model
 Defines schema and
terminology for representing
methods
 Consists of method content
and processes
12

RMC IS THE AUTHORING TOOL

RUP PRINCIPLES
 Adapt the process
 Balance competing stakeholder priorities
 Collaborate across teams
 Demonstrate value iteratively
 Elevate level of abstraction
 Focus continuously on quality

 Requirements Specifier
 Stakeholder
 Systems Analyst, etc.
 Task
 Find Use Cases and Actors

UMA PROCESS ELEMENTS
 Activity
 Activities define the breakdown as
well as flow of work (i.e. contain
sub-activities and tasks)
 Capability pattern
 A reusable cluster of Activities in
common process areas
 E.g., use case analysis, unit
testing, etc.
 Delivery process
 A complete and integrated
approach for performing a specific
type of project – i.e., a specific
SDLC
