    Study Notes

    Documentation of Requirements

    • The goal of documenting requirements is to ensure the current state of knowledge is accessible to all project participants.
    • The documentation of requirements serves as a communication tool within the project and is used to clarify and prioritize requirements.
    • It provides a knowledge repository for decisions and definitions and serves as a binding document in case of disputes.

    Activities for Documenting Requirements

    • The process of documenting requirements consists of four steps:
      • Determination of purpose and target group
      • Selection of the level of detail and documentation form
      • Documentation of requirements
      • Checking whether the documentation still fits the purpose and target group

    Determination of Purpose and Target Group

    • The purpose and target group of the documentation must be determined before documentation is created.
    • Typical goals for requirements documentation include:
      • Communication support for stakeholders
      • Knowledge repository for decisions and definitions
      • Binding document in case of disputes
    • The target group and purpose of the documentation can vary depending on the project situation.

    Levels of Detail

    • Requirements can be related to each other in a refinement hierarchy and can be assigned to one of four different levels of detail:
      • Rough system description
      • Use case
      • User requirement
      • Detailed user requirements
    • Each level describes the system completely, either very abstractly or in a more refined way.

    Selection of the Level of Detail and Form of Documentation

    • The level of detail and documentation form are selected based on the purpose and target group.
    • The level of detail depends on the use of the documentation, and different stakeholders may require different levels of detail.
    • Typical documentation forms include software models, prototypes, sketches, tables, and text.

    Documentation of Requirements

    • The requirements are documented in a form suitable for the purpose and target group.
    • Changes to the requirements are logged with the date and reason for the change to enable traceability.
    • Relationships between requirements are documented to prevent collateral changes.

    Checking Whether Documentation Still Fits Purpose and Target Group

    • The documentation is regularly reviewed to ensure it still fits the purpose and target group.
    • The documentation may need to be adapted to changed conditions.

    Typical Elements of Requirements Documentation

    • There is no uniform structure for requirements documents, but typical elements include:
      • Project vision
      • Overview level
      • Detailed requirements
      • Glossary
    • The project vision provides a common understanding of the project and communicates with stakeholders.
    • The overview level provides a general overview of the main system functions, technical interfaces, users, and classification in the system landscape.
    • The detailed requirements section documents each system function in detail.
    • The glossary defines industry- or company-specific terms and abbreviations to prevent confusion.### Forms of Requirements Documentation
    • Text and Tables: most frequently used documentation forms for information systems
    • Advantages:
      • Easy to use and understand
      • Can describe all types of requirements
    • Disadvantages:
      • Room for interpretation and inaccuracies in formulation of requirements
      • May not consider negative cases (e.g., what happens when something goes wrong)

    Structured and Formal Specifications

    • Example One: Structured Specification
      • Code 3.2. User function of myApp
      • Describes user actions and system responses
    • Example Two: Structured Detailed Specification
      • Code 3.2.1. Select
      • Describes user interface elements and behavior
    • Example Three: Semiformal Specification
      • Describes function, inputs, outputs, sequence, and exceptions
      • Can be reused as a template for other requirements
    • Example Four: Formal Specification
      • Written in code, compact but not easily understood by stakeholders without programming skills

    User Stories

    • A technique used in Agile development
    • Format: "As a [who], I want to [what], so that [why]"
    • Should contain an estimation of business value and effort required
    • Can be complemented with detailed written specifications, figures, models, or reference material
    • Evolve as understanding increases

    Sketches and Simple Graphics

    • Advantages:
      • Simple and quick to create
      • Can be used in workshops with stakeholders
    • Disadvantages:
      • Wide scope for interpretation if meaning is not described
      • Not suitable for permanent documentation

    Models

    • Distinction between graphical and textual models
    • Graphical models (e.g., BPMN, UML) used to document requirements for system structure and behavior
    • Textual models (e.g., RSL, PSL/PSA) used to formulate and formalize requirements

    GUI Prototypes

    • Suitable for documenting user interface requirements
    • Can be used to elicit requirements and as a form of requirements documentation
    • Can be created on different levels, from simple sketches to complete mock-ups### Requirements Specification
    • A specification with the same level of detail in all areas may indicate a waste of resources or a lack of detail.
    • Certain issues within a specification are more descriptive than others.
    • Typical elements of requirements documents include:
      • Project vision
      • Overview level
      • Detailed requirements
      • Glossary

    Project Vision

    • Formulating the project vision in text helps the project team develop a common understanding of the project.
    • The project vision should answer the following questions:
      • What is the goal or purpose of the project?
      • What is the motivation for the project?
      • What is the definition of the level of requirements described in the document?
    • The project vision is an introduction and guide to the contents of the document and can be used for the final check to establish whether the content and form still fit the purpose and target group.

    Overview Level

    • The overview level is used for the technical and functional classification of the application.
    • The overview level should include:
      • Location of the system in the business process landscape
      • Embedding of the system in the IT landscape of the organization
      • Brief description of the most important system functions
      • Technical interfaces to other systems
      • Brief description of the roles that will actively work with the system

    Detailed Requirements

    • Each system function described in the overview must be documented in detail before implementation.
    • Detailed requirements should include:
      • Functional requirements
      • Quality requirements
      • Constraints
      • Sub-functions
    • Documentation can be in the form of text, bulleted lists, tables, functional models, references to external documents, and screenshots of prototypes.

    Glossary

    • A glossary is necessary to define industry- or company-specific terms that may not be known by all project participants.
    • Tips for building a glossary:
      • Sort the defined terms alphabetically
      • Define technical terms
      • List synonyms or related terms that may have a different meaning
      • Define verbs to prevent misunderstandings
      • Describe adjectives and use legally binding modal verbs

    Forms of Documentation

    • Typical forms of requirements documentation include:
      • Models
      • Prototypes
      • Sketches
      • Tables
      • Text
    • The advantages of documentation in the form of text and tables lie in their ease of use and versatility.
    • Disadvantages include room for interpretation and inaccuracies in the formulation of requirements.

    User Stories

    • User stories are a popular technique used in Agile projects.
    • A well-written user story should include:
      • Who (the user)
      • What (the function)
      • Why (the motivation)
      • Business value (in a range of 1-10)
