Attributes of SW Design
Software design is actually a multi step process that focuses on four
distinct attributes of a program:
­ Data structure,
­ Software architecture,
­ Interface representations, and procedural (algorithmic) detail.
The design process translates requirements into a representation of the
software that can be assessed for quality before coding begins.
Like requirements, the design is documented and becomes part of the
software configuration.
Design is the technical kernel of software engineering. During design,
progressive refinements of data structure, architecture, interfaces, and
procedural detail of software components are developed, reviewed, and
Design results in representations of software that can be assessed for
quality. A number of fundamental software design principles and concepts
have been proposed over the past four decades.
Design principles guide the software engineer as the design process
proceeds. Design concepts provide basic criteria for design quality.
Software Project Management (CS615)
a. Code generation
The design must be translated into a machine-readable form. The
code generation step performs this task. If design is performed in a
detailed  manner,  code  generation  can  be  accomplished
b. Testing
Once code has been generated, program testing begins. The testing
process focuses on the logical internals of the software, ensuring
that all statements have been tested and on the functional externals;
that is, conducting tests to uncover errors and ensure that defined
input will produce actual results that agree with required results.
Key Features of Design
A number of fundamental software design principles and concepts have
been proposed over the past four decades. Design principles guide the
software engineer as the design process proceeds. Design concepts provide
basic criteria for design quality.
Software will undoubtedly undergo change after it is delivered to the
customer (a possible exception is embedded software). Change will occur
because errors have been encountered, because the software must be
adapted to accommodate changes in its external environment (e.g. a
change required because of a new operating system or peripheral device),
or because the customer requires functional or performance enhancements.
Software support/maintenance reapplies each of the preceding phases to
an existing program rather than a new one.
Modularity (in both program and data) and the concept of abstraction
enable the designer to simplify and reuse software components.
Refinement provides a mechanism for representing successive layers of
functional detail. Program and data structure contribute to an overall view
of software architecture, while procedure provides the detail necessary for
algorithm implementation.
Software Project Management (CS615)
Information hiding and functional independence provide heuristics for
achieving effective modularity.
We try to solve the problem by rushing through the design process so that
enough time will be left at the end of the project to uncover errors that
were made because we rushed through the design process.
The moral is this: Don't rush through it! Design is worth the effort.
Standard design approaches
Exception handling,
Memory management,
­ Coding practices
Naming, layout, documentation
­ Data-related concepts
Scope, persistence, binding time
­ Data usage guidelines
Bytes, arrays
­ Use of construction tools
Programming environment, group work support (documents, code),
code libraries & generators
Software Configuration management
Software configuration management (SCM) takes care of changes in a
software  process.  SCM  identifies  controls,  audits,  and  reports
modifications that occur during software development. SCM helps
maintain the integrity of configurable items produced during software
development. SCM is an integral part of Software Quality Assurance
(SQA). SCM involves assessing the impact of the changes made during
SQA activities and making decisions based on cost and benefit analysis.
SCM is used to establish and maintain integrity of software items and
ensure that they can be traced easily. SCM helps define a library structure
for storage and retrieval of software items.
Software Project Management (CS615)
To ensure that project stays consistent over time: You need to:
Evaluate proposed changes
Track the changes
Control the Version
Check integrity of Source code, documents, plans, design
Ensure quality
Software Configuration Management Activities
SCM is used to establish and maintain integrity of software items and
ensure that they can be traced easily. Using SCM, you can define a library
structure for storage and retrieval of software items. SCM needs to be
performed at all phases in the SDLC of a software project. The various
SCM activities are:
Identifying Objects
Controlling Versions
Controlling Changes
Communicating Changes
1. Identifying Objects
The first activity in SCM involves identifying software configurable
items (SCIs). SCI is an aggregation of software that is designated for
configuration management. It is treated as a single entity in the
configuration management process. For example, design documents,
program code, test case, and custom requirement document are
configurable items.
You can use the Item Traceability Matrix to identify SCIs at the end of
each phase. A sample of Item Traceability Matrix is displayed in Table
1. In the table, you can see the different SCIs in different phases of the
development process.

To identify SCls, you need to first breakdown the project deliverable
to the SCI level. Each phase in the project has its own deliverables. To
trace the deliverables, you need to map the SCls to the phases in which
they are delivered.
2. Controlling Versions
Version control combines procedures and tools to manage different
versions of configuration objects that are created during software
product development. To control versions, you can use Version
Control Register. In Version Control Register, you enter the details of
components, such as component identification numbers, their versions,
and dates of validity. It is advisable to release a baseline after a version
is released. Baseline is a specification or a product that is formally
reviewed and agreed upon. This serves as the basis for further
development. Baseline can be changed only through formal change
control procedures. A baseline consists of a set of SCIs that are
logically related to each other. Baselines are established when
subsequent changes to the SCIs need to be controlled. Version control
is essential so that everybody uses only the latest version. Any kind of
version mismatch might result in rework.
