Requirements EngineeringSystems Development


This episode covers the importance of requirements engineering in building systems, its global impact, types of requirements and techniques, and the integration of AI and agile mindset in requirements engineering.


Requirements engineering is crucial for system development

It ensures precision, accuracy, and reduces negative impacts on system changes.

Agile environments still require skills in requirements engineering

Shared understanding and documentation are necessary to reduce risk.

Requirements engineering has a global impact

The organization serving requirements engineering has certified professionals in 96 countries.

User requirements and system requirements differ in detail

Functional and non-functional requirements play important roles in system development.

AI can support requirements engineering process and system design

Critical thinking is essential when interpreting information generated by AI tools.

Introduction to Requirements Engineering

00:01 - 08:17

  • Requirements engineering is important when building systems from the ground up
  • IRAB (International Requirements Engineering Board) focuses on detailed requirements and requirements management
  • Stan is the managing director of IRAB
  • IRAB was founded in 2006 and offers certification for requirements engineering professionals
  • Requirements engineering involves eliciting user needs, documenting requirements, and managing changes
  • The term "engineering" emphasizes the precision and specification required in documenting requirements
  • Requirements engineering is applicable in industries such as automotive, aviation, and medical domains

The Importance of Requirements Engineering

07:50 - 16:23

  • Requirements engineering is about precision and accuracy to ensure that system changes do not have negative impacts
  • Financial domains require consideration of regulations and laws when defining system requirements
  • Requirements engineering also takes into account the impact on humans and ethics
  • Developing software for people involves addressing their fears and concerns during system changes
  • Agile settings still require skills in requirements engineering, business analysis, and testing
  • Agile environments also need shared understanding and documentation to reduce risk
  • Requirements engineering is necessary for reducing risk and providing what people need in systems development
  • Agile approaches allow for focusing on value creation and defining requirements step by step

Global Impact of Requirements Engineering

15:54 - 24:22

  • Requirements engineering has a big upfront effort, but it is necessary
  • The audience is asked if they have heard of requirements engineering and if they have any questions
  • Requirements engineering and business analysis communities have synergies, especially in Europe
  • The organization serving requirements engineering is located in Europe but has a global impact with certified people in 96 countries
  • There is interest in requirements engineering from the US and Canada, although maybe not in certifications
  • The organization's focus is to create awareness about the necessity of requirements engineering
  • Requirements engineering is a specialized skill set within the broader business analysis body of knowledge
  • Requirements engineers work closely with business analysts to define systems and support business processes with IT solutions
  • Requirements engineering can enhance the work of technical business analysts

Types of Requirements and Techniques

23:53 - 32:10

  • User requirements are about what is desired by a user for a user interface functionality
  • System requirements are more detailed and focus on things like scalability and data storage
  • Functional requirements refer to the functionality provided by the system
  • Non-functional requirements are quality requirements that enhance the system's performance, availability, security, reliability, etc
  • Constraints are requirements that limit the solution space, such as hardware or operating system specifications
  • Requirements engineering techniques include brainstorming, interviews, analysis, and observation
  • Quality requirements can be gathered using a checklist based on ISO's quality model
  • Stakeholders may not always speak up during requirement elicitation; techniques like observation can help in such scenarios

Integration of AI and Agile Mindset in Requirements Engineering

31:46 - 40:22

  • Requirements engineering can benefit from artificial intelligence (AI) in two ways: supporting the process and designing systems with AI
  • AI can help define requirements in a clear and structured way, but it's important to validate the information generated by AI tools
  • Critical thinking is crucial when interpreting information from AI tools, as they can present information confidently even if it's not true
  • Requirements engineering aligns well with the principles of agile mindset, especially in terms of creating a shared understanding before documentation
  • There are various tools available for requirements engineering, such as IBM's DOORS and web-based options
  • A link to a website providing an overview of requirements engineering tools will be shared in the YouTube description
