How can you anticipate and adapt to evolving system requirements?

Considering the rapid pace of technological advancements, it’s essential to not only recognize current trends but also anticipate future shifts in technology. Certain technologies may seem unrelated to our product during the design and development phases, yet become relevant once the product is in service. A good example of this is the over-the-air (OTA) updates for embedded systems. These systems require certain hardware and software features to support OTA. Without these features, it becomes practically impossible to incorporate new technologies into your product as they emerge.

To lay a robust foundation for effective systems engineering, the initial imperative is a comprehensive understanding of the system context. This encompasses a meticulous examination of the environment and conditions within which the system operates and engages. The system context, a nuanced composite, involves delineating the system's purpose, establishing the boundaries that encapsulate its scope, elucidating its interfaces, and recognizing the prevailing constraints, assumptions, and risks.

You indeed were pushing virtualization for years now Rick. Most of us around The Beltway recognize your leadership in this and other areas. V/R

Please understand your client expectation and user context of the system before doing anything, and influence your client to understand their actual needs from the universe.

Watch Technology trends and allow for them to grow, too far in front will frustrate you. Great examples, the Internet of Things (IOT) never took off, 5G taped about it 10 years ago and now its normal, Zero Trust another example of being to far in front, but it here today. The growth of Virtual work space is impacting everything, I have promoted this for 20 years and now it's every body else who had the goat idea. Leadership and innovation are not about credit but about planting seeds and helping them grow.

With advancement in techologies and strigent regulatory guidelines it is very essential to capture the requirements precisely as this lays the foundation for the down stream activities in the design and development. Capturing the requirements via 4C3T Clarity, Completeness, Correctness, Consistency, Testability, Traceability and aTtainability principle ensures the requirements are captured in full and maintained during the entire product life cycle.

Requirements must embody clarity, conciseness, consistency, verifiability, traceability, and feasibility. These formal statements outline what the system must achieve, the standards it should meet, and the conditions under which it operates. Effective prioritization is paramount. Assessing importance, urgency, and interdependencies is crucial, considering factors like customer value, technical risk, regulatory compliance, and resource availability. This prioritization strategy sharpens focus on critical aspects, facilitating trade-off management and conflict resolution among competing requirements.

Should we need to describe the Requirement specifications as part of statement of concept of operation, which the end users need to complete their mission? Then the requirement specification is directly converted into system requirements. The most essential items have been carefully derived from the initial steps using RPN, Requirement Priority Number!

Requirements shall be SMART. Specific Measurable Actionable Readable and easy understandable Testable The above characteristics makes the requirements absolute and independent

Clarity and Conciseness: Clear and concise requirements form a solid foundation for development. Consistency: Ensuring consistency prevents conflicts during the development process. Verifiability: Verifiable requirements enable systematic validation and verification. Traceability: Establishing traceability facilitates effective change management. Feasibility: Feasible requirements are essential for practical implementation. Prioritization Criteria: Prioritizing based on importance, urgency, and dependency guides effective trade-off management. Alignment with Criteria: Criteria like customer value and regulatory compliance ensure focus on critical aspects.

Change Control: The ability to control and communicate changes ensures that the system requirements are managed effectively throughout the entire life cycle. Baseline Establishment: Establishing a baseline of agreed-upon requirements provides a stable foundation for ongoing system development. Change Tracking: Tracking and documenting changes and deviations enable a transparent record of the system requirements evolution. Impact Analysis: Analyzing and evaluating the impacts of changes ensures a comprehensive understanding of their effects on the system. Stakeholder Communication: Communicating and coordinating changes with all relevant stakeholders ensures alignment with system context and stakeholder expectations.

Make sure to avoid "scope creep", by: - Monitoring the project requirements needs. - Enumerate and classify effort in high level view of complexity, time to delivery and value to company - Keep stakeholders alignment with a timeline relation of head count and task distribution

- Invest in the establishment of good change management and configuration management processes; - Pay attention to requirements’ attributes. Bidirectional traceability between requirements and also between requirements and other work products will help to identify what have a good chance to be impacted by a given change. ‘Rational’ will help to understand the impacts of changing its associated requirement. ‘Owner’ reveals who you should to talk to before promoting any changes on a given requirement. And so on.

System requirements management is a multifaceted endeavor involving: -Baselining System Requirements: Forming a foundational baseline of mutually agreed-upon system requirements. -Tracking and Documenting Changes: Methodically recording alterations and deviations from the established baseline. -Impact Analysis: Analyzing and evaluating the effects of system requirements changes. -Communication and Coordination: Engaging in effective communication and coordination with all relevant stakeholders regarding changes. This systematic approach ensures that system requirements remain aligned with the system context and stakeholder expectations

The so-called baseline is critical. Both system dev team and stakeholders should establish 3 levels of expectations: (1) the maximum quality (2) the most likely (3) the lowest with acceptable quality as part of go and no-go decision (Decision team: Budget sponsor and project owner) and used for acceptance criteria too.

An important approach for verification and validation of system requirements is simulation at the early stages of product development. With simulation unified with systems engineering, we can transform the product development cycle to ‘shift-left’, thereby catching and fixing flaws early, saving time and cost by avoiding rework in the later cycle. Simulating the operational behaviour of the system and refining requirements based on the feedback, we develop a robust system with faster time to market.

? Necessary for operational effectiveness: If the system has this characteristic, will the user need be satisfied? ? Necessary for operational suitability: If the system has this characteristic, will it be fit for use in its intended environment and operations life cycle?

In systems, validating requirements isn't a one-off task; it's an ongoing reality check. It's not just about confirming correctness initially; it's consistently ensuring the system aligns with stakeholder needs and the intended solution. Developing something isn't a set-and-forget deal. It's an evolving process. While system requirements verification is crucial for performance confirmation, ongoing validation is equally vital. It means regularly checking in with users, figuring out what works, and, importantly, what could work better. System evolution isn't a one-shot game; it's a journey. Effective outcomes come from a continuous loop of validation, keeping the system responsive to evolving needs.

Should we do dev and do dev test to ensure that all components and sub sys both h/w, and s/w are functioning per quality goals? After that the qualification test to evaluate system functional is conducted to ensure system conformity to the established expectation and acceptance criteria prior pursuit the delivery and acceptance test with customers.

- Accurate and complete system validation and verification depend on well-defined and unambiguous requirements. - Continuous alignment with stakeholder needs guarantees that the system meets user expectations during validation. - Identifying issues and ensuring performance under diverse scenarios is assured through comprehensive testing. - Efficient allocation of resources ensures thorough and effective validation and verification. - Well-defined and measurable success criteria provide clear endpoints for the validation and verification process, ensuring completeness.

Identification of Triggers and Opportunities: Recognizing triggers like feedback, issues, requests, or innovations, ensures proactive responsiveness to evolving needs. Assessment of System Evolution Triggers: Evaluating triggers provides insights into the necessity and potential directions for system evolution. Proposal and Evaluation of Alternatives: Proposing enhancements, modifications, or replacements allows for a comprehensive assessment of viable options. Implementation and Testing: Implementing and testing selected solutions, such as prototypes, pilots, or releases, ensures the effectiveness of the chosen system evolution path.

In my experience, working with business stakeholders to identify desired state and functionality for their employees and client satisfaction is key to understanding how the system will evolve as utilized. Another way of staying ahead of this, is to understand the compliance objectives you have as an organization and to closely follow any updates from those requirements such as DFARs 252.204-7012’s usage of the NIST 800-171 framework with its upcoming revision 3. As a final note, staying informed and utilizing current threat protection data to secure your application, is paramount in ensuring the integrity/security of the system for your users/stakeholders and ultimately, the public trust of your system.

A quinta etapa é evoluir os requisitos do sistema, que é o processo de adapta??o e atualiza??o dos requisitos do sistema para refletir as necessidades novas ou em mudan?a das partes interessadas, o contexto do sistema ou o desempenho do sistema. A evolu??o dos requisitos do sistema envolve identificar e avaliar os gatilhos e oportunidades para a evolu??o do sistema, como feedback, problemas, solicita??es ou inova??es, propor e avaliar as alternativas e op??es para a evolu??o do sistema, como melhorias.

You should be prepared to adapt the system requirements to the changing needs and feedback of the stakeholders, as well as the emerging opportunities and challenges in the system context. You should also evaluate the impact of the changes on the system design, development, testing, and deployment. A proactive approach to evolution prevents rigidity and ensures the system stays relevant and effective. This might involve phased rollouts or modular design for easier adaptation.

é imprescindível conhecer o sistema utilizado por completo e o passo a passo de cada componente(equipamento), o que cada um faz/ poderia fazer, se algum já trabalha no seu limite e qualidade. Após isso analisar a forma de trabalho constante, processar as informa??es coletadas e ir adaptando as necessidades diárias, planejando com ordem as suas altera??es e manuten??es preventivas/corretivas. Com estes passos e a mente fértil, naturalmente vir?o as ideias e sugest?es evolutivas para o aperfei?oamento do seu próprio trabalho! E boa Sorte!

Performance Measurement and Monitoring: Continuously measure and monitor system evolution performance in terms of functionality, usability, reliability, and maintainability. Feedback and Opinion Gathering: Collect and review feedback and opinions on the system evolution, focusing on satisfaction, expectations, and preferences. Application of Best Practices: Apply and share best practices and recommendations, including standards, guidelines, and tools, to enhance the system evolution process.

You should continuously monitor and measure the performance and satisfaction of the system and its stakeholders. You should also identify the lessons learned and best practices for improving the system requirements management process. A feedback loop fuels continuous improvement. This ensures requirements remain aligned with evolving needs and address emerging challenges.

Work with your business partners, not against them. Understanding the needs of the business and designing the system to support those needs is essential to a properly functioning and secure system. When the system works against the business or when processes to add and change functionality become too burdensome, the business will work around and against Security & IT to get the job done.

When cost is not the factor included and requirements change rapidly. A Cloud/hyper-converge system is the way to go. You'll have the flexibility to increase and decrease resources accordingly at a quicker pace as the traditional getting vendor quotation is a risk itself when the process of getting approval and quotation will take most of the allocated time when dealing with a new project.

Key requirement identification and finding out weak links in the system from system architecture/context diagram are important. Discussion with customer and stakeholders does help which does give insight on business needs and trends in market. We can understand changes based different platforms development customer is working on. Based on same, one can anticipate changes and opportunities coming in future.

When we talk about evolving technological advancements in particular with the system and its requirements...we have to understand that a particular system is initially conceptualized..... with its drawing and design.... manufacturing.. monitoring.... production and its marketing.....are done keeping the latest technology present at that time..... but always the technology is evolving .....we have to anticipate and adapt to the evolving technological advancements in system requirements with its safety culture also ..... so that the evolving trends in system requirements are infused into the present systems and are continuously updated and communicated with the stakeholders.... and the same is again monitored for its adaptability.

Pay attention to the customer and the customer's environment. Will larger trends affect the needs of the customer or solution? If so, count on the need for change and be ready.
