Topics to be Covered
• Software Engineering
• The Software Process
• A Process Framework
• Framework Activities
• Umbrella Activities
• Process Adaptation

Software Engineering
Some realities:
• A concerted effort should be made to understand the problem
before a software solution is developed. (Understand the
problem before build a solution)
• Design becomes a pivotal activity.
• Software should exhibit high quality.
• Software should be maintainable.(fix bugs or add new features).

• SE means using proper engineering methods and principles to build
software
• In order to obtain economically software that is reliable and works
efficiently on real machines.
• The IEEE definition:
⮚Software Engineering: The application of a systematic, disciplined,
quantifiable approach to the development, operation, and
maintenance of software; that is, the application of engineering to
software.

8
Methods and Tools
Method
• Provides technical how-tools for building software.
• It encompasses many tasks including communication, requirement analysis, design
modeling, program construction, testing and support.
Tools
• Provide automated or semi-automated support for the process and methods.
• When tools are integrated so that information created by one tool can be used by another.
• A system for the support of software development, called computer-aided software
engineering(CASE) is established.(faster, more efficient, and better organized)

The Software Process
 A process is a collection of activities, actions and tasks that are
performed when some work product is to be created.
 An activity – strives to achieve a board objective.
(Example: Communication with stakeholders)
 An action - a set of tasks that produce major work product
(Example: Architectural design)
 A task - focuses on a small, but well defined.
(Example: Conducting a unit test)

10
A Process Framework
 Establishes the foundation for a complete software
process
 Identifies a number of framework activities applicable
to all software projects
 Also include a set of umbrella activities that are
applicable across the entire software process.

Five Activities of Process Framework
1) Communication
2) Planning
3) Modeling
4) Construction
5) Deployment.
Continues…

12
Communication: Discuss with customers and stakeholders to
understand their needs and gather software requirements.
Planning: Create a detailed project plan outlining tasks, risks,
resources, deliverables, and timelines.
Modeling: Design models (like sketches) to visualize the software’s
structure and behavior before building it.
Construction: Write and test the code to develop a working product.
Deployment: Deliver the software to the customer for use and
feedback.

13
Umbrella activities
 Software engineering process framework activities are
complemented by a number of umbrella activities.
 Umbrella activities are applied throughout a software project
and help a software team manage and Track progress,
Maintain quality, Handle changes, and Manage risk.

14
Typical umbrella activities include:
• Software project tracking and control
• Risk management
• Software quality assurance
• Technical reviews
• Measurement
• Software configuration management
• Reusability management
• Work product preparation & production

15
Software project tracking and control:
Allows the software team to assess progress against the project plan
and take any necessary action to maintain the schedule.
Risk management:
Assesses risks that may affect the outcome of the project or the
quality of the product.
Software quality assurance:
Defines and conducts the activities required to ensure software
quality.

16
Technical reviews:
Assesses software engineering work products in an effort to uncover
and remove errors before they are propagated to the next activity.
Measurement:
Defines and collects process, project, and product measures that
assist the team in delivering software that meets stakeholders’ needs; can be
used in conjunction with all other framework and umbrella activities.
Software configuration management:
Manages the effects of change throughout the software process.

17
Reusability management:
Defines criteria for work product reuse (including software
components) and establishes mechanisms to achieve reusable
components.
Work product preparation and production:
Encompasses the activities required to create work products
such as models, documents, logs, forms, and lists.

18
Process Adaptation
 Process Adaptation refers to the ability to modify and tailor
the software engineering process based on the specific
needs of a project, team, or organization.
 It means that the software process is not fixed—Key aspects
that may vary include the workflow, task detail, quality
checks, team roles, and customer involvement.
 Process Adaptation is about making the process flexible and
suitable for each unique situation
Continue,..

19
 Overall flow of activities, actions, and tasks and the interdependencies
among them
 Degree to which actions and tasks are defined within each framework activity
 Degree to which work products are identified and required.
 Manner in which quality assurance activities are applied
 Manner in which project tracking and control activities are applied
 Overall degree of detail and rigor with which the process is described
 Degree to which the customer and other stakeholders are involved with the
project
 Level of autonomy given to the software team
