    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

    • 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.
