Study Notes
Why BMC Matters in Software Development
- Aligns software features with business goals
- Ensures software solves the right customer problems
- Guides development resources and costs
- Enhances product delivery and customer satisfaction
Customer-Centric Development
- Value Proposition: Defines the problem that the software must solve
- Customer Segments: Identifies the target audience for the software
Resource and Cost Management
- Key Resources and Cost Structure: Dictate available technologies, tools, and budget
Effective Product Delivery
- Channels: Defines how the software will reach the user (web, mobile, third-party platforms)
- Customer Relationships: Guides support and post-launch features
Revenue-Driven Features
- Revenue Streams: Ensures the software aligns with the business's monetization strategy
Iterative Development & Innovation
- Key Partners and Key Activities: Foster partnerships that enable quicker development
- Key Partners and Cost Structure: Help identify potential risks (e.g., technology limitations)
Software Requirements Engineering
- The process of establishing the services that the customer requires from a system
- Requirements may be functional or non-functional
What is a Requirement?
- May range from a high-level abstract statement of a service or of a system constraint to a detailed mathematical functional specification
Types of Requirements
- User Requirements: Statements in natural language (NL) plus diagrams of the services the system provides and its operational constraints. Written for customers
- System Requirements: A structured document setting out detailed descriptions of the system services. Written as a contract between client and contractor
- Software Specification: A detailed software description which can serve as a basis for a design or implementation. Written for developers
Requirements Types
- Functional Requirements: Services the system should provide
- Non-Functional Requirements: Constraints on the services or functions offered by the system
- Domain Requirements: Related to the application domain of the system (may be functional or non-functional requirements)
Business Model Canvas (BMC) and its importance in Software Development
- Aligning software features with business goals.
- Ensuring software solves the right customer problems.
- Guiding development resources and costs.
- Enhancing product delivery and customer satisfaction.
Understanding Customer Problems
- Defines the problem that the software must solve.
- Ensures the development focuses on delivering value to the end-user.
- Helps developers design solutions that directly address customer pain points.
Designing With The Customer In Mind
- Identifies the target audience for the software.
- Guides decisions on user interface, experience, and features.
- Ensures different user groups are considered in the software’s design.
Optimizing Resources and Costs
- Dictate available technologies, tools, and budget.
- Helps balance quality and budget constraints.
- Ensures development remains cost-effective while delivering required functionality.
Delivering the Product to the Right Audience
- Defines how the software will reach the user (web, mobile, third-party platforms).
- Ensures developers build software that fits the business’s delivery strategy.
- Guides support and post-launch features.
Supporting Business Revenue
- Ensures the software aligns with the business’s monetization strategy.
- Guides feature development for freemium, subscription, or in-app purchases.
- Helps prioritize high-value features.
Encouraging Continuous Improvement
- Foster partnerships that enable quicker development.
- Promotes continuous improvement through integration with third-party tools.
- Encourages innovative solutions to optimize the development process.
Mitigating Risks In Development
- Help identify potential risks (e.g., technology limitations).
- Enables early risk mitigation by aligning development with business stability.
- Supports proactive decision-making to prevent issues during software development.
Software Requirements Engineering and Understanding Software Requirements
- Process of establishing the services that the customer requires from a system and the constraints under which it operates and is developed.
- Requirements may be functional or non-functional.
- Functional: Description of the system services or functions.
- Non-functional: Constraint on the system or the development process.
Types of Requirements
- User Requirements: Statements in natural language (NL) plus diagrams of the services the system provides and its operational constraints. Written for customers.
- System Requirements: A structured document outlining detailed descriptions of the system services. Written as a contract between client and contractor.
- Software Specification: A detailed software description that can serve as a basis for a design or implementation. Written for developers.
Requirements Targets
- Functional Requirements: Services the system should provide.
- Non-functional Requirements: Constraints on the services of functions offered by the system.
- Domain Requirements: Related to the application domain of the system (may be functional or non-functional requirements)
Problems with Natural Language
- Lack of clarity and precision.
- Requirements confusion between functional and non-functional.
- Requirements amalgamation.
- Ambiguity.
- Over-flexibility.
Alternatives to Natural Language
- Structured Natural language.
- Program Description Language (PDL).
- Use-Cases.
- Mathematical specification.
PDL-Based Requirements Definition
- Requirements may be defined operationally using a language like a programming language but with more flexibility of expression.
- Most appropriate when an operation is specified as a sequence of actions and the order is important, and when hardware and software interfaces have to be specified.
The Requirements Document
- Official statement of what is required of the system developers.
- Should include both a definition and a specification of requirements.
- It is NOT a design document.
Requirements Engineering (RE) Processes
- Processes used to discover, analyse and validate system requirements.
- RE vary widely depending on the application domain, the people involved and the organization developing the requirements.
-
Generic activities:
- Requirements elicitation
- Requirements analysis
- Requirements validation
- Requirements management
Problems of Requirements Analysis
- Stakeholders don't know what they really want.
- Stakeholders express requirements in their own terms.
- Different stakeholders may have conflicting requirements.
- Organizational and political factors may influence the system requirements.
- The requirements change during the analysis process.
Use Case Modeling
- Use-cases: A scenario based technique in the UML that identifies the actors in an interaction and which describe the interaction itself.
- A set of use cases should describe all possible interactions with the system.
- Sequence diagrams may be used to add detail to use-cases by showing the sequence of event processing in the system.
