1. Software Engineering Process

2. Overview
• Software Engineering Process is the systematic
approach to software development.
• It involves defining, implementing, and managing
software projects.
• Conventional and modern approaches offer
different methodologies and frameworks.
• These processes guide the development lifecycle
from requirements to deployment.

3. Conventional Approaches
• Conventional approaches follow linear, sequential
development methodologies.
• Examples include the Waterfall Model and the V-
Model.
• They emphasize comprehensive planning and
documentation upfront.
• Conventional approaches are well-suited for
projects with stable requirements.

4. Limitations of Conventional Approaches
• Conventional approaches may struggle with
accommodating changing requirements.
• They can result in lengthy development cycles
and delayed feedback.
• Limited flexibility and adaptability can lead to
project risks and failures.

5. Modern Approaches
• Modern approaches, such as Agile, Lean, and DevOps,
prioritize flexibility and adaptability in software
development.
• Agile methodologies emphasize iterative and incremental
development, frequent customer collaboration, and the
delivery of working software.
• Lean focuses on maximizing value while minimizing waste
and emphasizes continuous improvement and flow.
• DevOps promotes collaboration between development and
operations teams, automation, and continuous delivery.

6. Advantages of Modern Approaches
• Modern approaches offer increased flexibility to adapt
to changing requirements or market conditions.
• They promote collaboration and communication
among team members, stakeholders, and customers.
• Rapid iterations enable quicker delivery of valuable
software increments, allowing for early feedback and
course correction.
• Modern approaches foster a culture of continuous
improvement and innovation, enhancing team morale
and productivity.

7. Challenges of Modern Approaches
• Modern approaches may require a cultural shift
within organizations, challenging traditional ways
of working.
• Balancing flexibility and predictability can be
challenging, particularly in larger or more
regulated environments.
• Continuous integration and delivery demand
robust automation, testing, and deployment
practices to ensure quality and reliability.

8. Selecting the Right Approach
• Choosing between conventional and modern
approaches depends on project requirements,
constraints, and organizational culture.
• Consider factors such as project size, complexity,
criticality, stakeholder needs, and market dynamics.
• Hybrid approaches, combining elements of both
conventional and modern methodologies, are
increasingly common and may offer the best of both
worlds.

9. Cont..
• Understanding both conventional and modern
approaches is essential for effective software
development.
• Each approach has its strengths and weaknesses,
catering to different project contexts and
organizational cultures.
• By selecting the right approach and adapting to
changing circumstances, teams can enhance
project success and deliver value to stakeholders.

10. Software Requirements Analysis
• Software Requirements Analysis is the process of identifying,
documenting, and managing software needs and functionalities.
• It involves understanding the goals and objectives of the software
project, as well as the needs and expectations of stakeholders.
• The primary objective is to establish a clear and unambiguous set
of requirements that serve as the foundation for software
development.
• Requirements analysis encompasses gathering, analyzing,
prioritizing, and validating requirements to ensure that the final
product meets user needs and expectations.
• It is a critical phase in the software development lifecycle, laying
the groundwork for system design, implementation, and testing.

11. Software Requirements Analysis
• Let's delve deeper into the methodologies
used
Conventional Approach
– Relies on traditional techniques
– Includes interviews, surveys, document analysis
– Emphasizes documentation, structured processes
– Suitable for stable requirements
– May struggle with evolving needs
– Long cycles, delayed feedback common

12. Cont..
• Limitations of Conventional Analysis
– May struggle with evolving requirements.
– Long development cycles and delayed feedback are
common.
– Limited adaptability may lead to project risks.
• Object-Oriented Analysis
• Models requirements using OOP principles.
• Defines objects, classes, and their relationships.
• Provides a natural and intuitive method for
requirements modeling.

13. Object-Oriented Analysis
• Models requirements using OOP principles.
• Defines objects, classes, and their relationships.
• Provides a natural and intuitive method for
requirements modeling.
• Starts with identifying objects and classes.
• Next, defines the relationships between these
objects.
• Finally, refines attributes and behaviors.
• This iterative process ensures a comprehensive
requirements model.

14. Object-Oriented Analysis
• Advantages of Object-Oriented Analysis
– Promotes reusability and modularity.
– Aligns the software solution closely with the
problem domain.
– Complex systems and interactions are represented
clearly.
– Let's compare these advantages to the strengths
of Conventional Analysis.

15. Object-Oriented Analysis
• Limitations of Object-Oriented Analysis
– Demands a solid understanding of OOP concepts.
– Over-engineering is a risk if not applied judiciously.
– Transitioning from analysis to design requires effort.
• Understanding both conventional and object-
oriented approaches is essential.
• By selecting the appropriate method, teams can
enhance project success.

16. Software Project Planning and
Estimation
• Overview of Software Project Planning
– Software Project Planning involves defining project
goals, objectives, and deliverables.
– It includes identifying project stakeholders and
establishing project scope and constraints.
– Effective planning ensures clear communication,
resource allocation, and risk mitigation strategies.
– Understanding the Fundamentals of Project
Planning and Estimation
– Initiating the Exploration into Software Project
Planning

17. Software Metrics
• Software Metrics are quantitative measures used
to assess various aspects of the software
development process.
• Metrics provide insights into project progress,
quality, and efficiency.
• Understanding the Importance of Software
Metrics in Project Management
• Initiating the Exploration into Software Metrics

18. Cost Estimation
• Cost Estimation involves predicting the financial
resources required for project completion.
• Various techniques are used for cost estimation,
including parametric estimation, analogy-based
estimation, and expert judgment.
• Accurate cost estimation is essential for budget
planning, resource allocation, and project feasibility
assessment.
• Effective cost estimation helps in identifying potential
risks and ensures that projects are delivered within
budget constraints.
• Understanding and mastering cost estimation
techniques are fundamental for project managers and
stakeholders.

19. Resource Allocation
• Resource Allocation involves identifying and assigning the
necessary resources for project execution.
• Resources include human resources, hardware, software,
and facilities required to complete project activities.
• Effective resource allocation ensures that project activities
are adequately supported and completed on time.
• Techniques such as resource leveling, resource smoothing,
and critical path method are used to optimize resource
allocation.
• Mastering resource allocation techniques is essential for
project managers to achieve project objectives efficiently.

20. Risk Management
• Risk Management involves identifying, assessing, and
mitigating potential risks that may impact project objectives.
• Risks can include technical challenges, resource constraints,
stakeholder conflicts, and external dependencies.
• Effective risk management minimizes project disruptions and
maximizes opportunities for project success.
• Techniques such as risk identification, risk assessment, risk
mitigation, and risk monitoring are used to manage project
