Study Notes

Software Processes - Lecture 1

Software processes are the activities involved in producing a software system
Software process models are abstract representations of these processes.
General process models describe the organization of software processes, with examples such as the waterfall model, incremental development, and reuse-oriented development.
The waterfall model is a plan-driven process. Separate and distinct phases of specification and development are used
Incremental development interleaves specification, development, and validation. It can be plan-driven or agile
Reuse-oriented software engineering assembles a system from existing components. It can be plan-driven or agile
In practice, large systems often incorporate elements from multiple models
Activities in the development process include specification, design, implementation, validation, and evolution
Specification: defines what the system should do
Design & Implementation: determines system organization and implements it
Validation: checks if the system meets customer needs
Evolution: modifies the system in response to changing customer needs

Topics Covered in Lecture

Software process models
Process activities
Coping with change
The Rational Unified Process (RUP) as an example of a modern software process

The Software Process

A structured set of activities required to develop a software system
Key activities include:
- Specification: Defining what the system should do
- Design & Implementation: Defining system organization and implementing the system
- Validation: Checking whether the system meets customer needs
- Evolution: Modifying the system in response to changing customer needs

Software Process Descriptions

Discussions about software processes often involve activities, such as specifying a data model or a user interface, and the order of those activities
Process descriptions may include products (outcomes), roles (responsibilities of people involved), and pre- and post-conditions (statements that are true before and after the process or product production).

Plan-driven and Agile Processes

Plan-driven processes have all process activities planned in advance, with progress measured against this plan.
Agile processes focus on incremental planning and adjustments to reflect changing customer requirements.
Practical software processes typically combine elements of both approaches.

Software Process Models

Waterfall model: Plan-driven model. Distinct phases of specification and development
Incremental development: Specification, development, and validation are interleaved. May be plan-driven or agile.
Reuse-oriented software engineering: System is assembled from existing components. May be plan-driven or agile

Waterfall Model Phases

Requirements definition
System and software design
Implementation and unit testing
Integration and system testing
Operation and maintenance

Waterfall Model Problems

Inflexible partitioning makes responding to changing customer requirements difficult.
The model is best suited for projects with stable requirements.
It's primarily used in large system engineering with multiple sites.

Incremental Development Benefits

Reduced cost of accommodating changing requirements
Fewer analysis and documentation issues compared to waterfall models
Easier to get customer feedback through demonstrations
Facilitates faster delivery and deployment of useful software

Incremental Development Problems

Process invisibility, requiring regular deliverables to monitor progress.
Documenting each incremental version can be inefficient when systems are developed quickly
System structure tends to degrade with each new increment unless refactoring takes place.

Reuse-oriented Software Engineering

Based on systematic reuse of existing components (Commercial-off-the-shelf (COTS))
Process stages include component analysis, requirements modification, system design with reuse, and development and integration.

Types of Software Components

Web services (remote invocation)
Object collections (integrated with frameworks like .NET or J2EE)
Stand-alone software systems (configured for specific use cases)

Process Activities

Real software processes are sequences of technical, collaborative, and managerial activities aimed at specifying, designing, implementing, and testing a software system.
Specification, development, validation, and evolution are typically organized differently across various development processes

Software Specification

Establishing required services and constraints on system operation/development
Requirements engineering process

The Requirements Engineering Process

Feasibility studies: Determining technical and financial feasibility
Requirements elicitation and analysis: Understanding stakeholders needs
Requirements specification: Detailing the requirements
Requirements validation: Checking validity of requirements

Software Design and Implementation

Converting system specifications into an executable system
Software design components
- Designing software structure achieving specification
Implementation aspects
- Translating design structure into an executable program
Design and implementation activities closely related and may be interleaved

A General Model of the Design Process

Design inputs: Platform information, software requirements, data descriptions
Design activities: Architectural design, interface design, database design, component selection and design
Design outputs: System architecture, database design, interface specification, component descriptions

Design Activities

Architectural design: Identifying system structure, components, their relationships and distribution
Interface design: Defining interfaces between system components
Component design: Designing the operation of each system component
Database design: Designing system data structures

Software Validation

Verification and validation (V&V) confirms that the system complies with its specifications and fulfills customer requirements
System testing: Executing the system with test cases derived from specifications
Testing is a commonly used Validation and verification (V&V) activity

Testing Stages

Development or component testing
Individual components are tested independently
Components may be functions, objects, or coherent groupings of these entities.
System testing
Testing the system as a whole. Testing for emergent properties is particularly important
Customer acceptance testing
Testing with customer data to ensure the system meets customer needs

Testing Phases in a Plan-driven Software Process

Requirements specification
System specification
System design
Component Design
Customer test plan
System integration test plan
Subsystem integration test plan
Customer test
System integration test
Subsystem integration test
Component code and test

Software Evolution

Software is inherently modifiable
Changing business circumstances often require software alterations

System Evolution

Defining system requirements
Assessing existing systems
Proposing system changes
Modifying systems

Key Points

Software processes are activities involved in producing software systems.
Software process models are abstract representations of these processes.
General process models describe the organization of software processes.

Key Points (continued)

Requirements engineering is the process of detailing the software specification
Design and implementation processes transform specifications into executable software
Software validation checks if the system functions as expected and meets users' needs
Software evolution involves modifying systems in reaction to new requirements

Coping with Change

Change is inevitable in large software projects
Business changes, new technologies, and evolving platforms all contribute to change in software projects
Change involves rework, which requires both re-analysis and implementation of new functionality

Reducing Costs of Rework

Change Avoidance: anticipates changes before substantial rework is needed
Example: A software prototype to demonstrate system features before development
Change Tolerance: Designs the process to allow for changes at low cost
Example: Incremental development where changes are implemented in increments that haven't been developed yet.

Software Prototyping

A prototype is an initial version of a system used to demonstrate concepts and design options in the following areas:
Requirements elicitation and validation
Design explorations and UI development
Testing processes for back-to-back tests

Benefits of Prototyping

Better system usability.
Closer match to users' real needs.
Improved design quality.
Improved maintainability.
Reduced development effort.

The Process of Prototype Development

Steps to developing a prototype

Establish prototype objectives
Define prototype functionality
Develop prototype
Evaluate prototype
Prototyping plan
Outline definition
Executable prototype
Evaluation report

Prototype Development

Prototypes can be based on rapid prototyping languages/tools.
Prototypes can omit aspects of the project that are not well understood, such as error checking and recovery.

Throw-away Prototypes

Prototypes should be discarded after development. They are not suitable for use in production.
Prototypes are often poorly documented and their structure usually degrades quickly with change.

Incremental Delivery

Software is delivered in increments, each delivering part of the functionality
User requirements are prioritized with highest priority requirements included in early increments.
Requirements are frozen for each increment while future increments can evolve and add additional features.

Incremental Development and Delivery

Develop the system in increments and evaluate before proceeding.
Normal practice in Agile methods
Evaluate with user/customer proxy.
Incremental delivery strategy
Deploy an increment for use by end-users
More realistic assessment of the completed incremental aspect of the system.
Replacing systems using incremental strategy is more complex; increments have less functionality than system being replaced

Incremental Delivery Advantages

System functionality available earlier to the customer
Early increments act as prototypes, helping to elicit customer feedback and requirements for future increments
Lower risk of project failure
Highest priority system services receive the most testing

Incremental Delivery Problems

Most systems need basic facilities used throughout the system.
Difficulty in defining common facilities needed by all increments.
Conflict with procurement models, where the entire system's specification is part of the development contract
