¿Cómo navegarías por las opiniones contradictorias sobre las decisiones de arquitectura de software dentro de tu equipo?

There is never a conflict on design decisions, a Architect has to be fluid like water, and understand different viewpoints, take inputs and apply the best possible fit in the actual designs. Architect is the one who understands, Business, Cyber Security Posture, Design specific best practices and the technology capabilities. The audiences can have a narrow vision based on their expertise, but as an Architect I have to be the bridge and not a blocker.

Our decision-making process is anchored in evaluating how new software architectures can sustainably impact our clients' business operations and profitability. We assess whether the proposed architectures align with our vision, add value, and importantly, reduce costs. This approach ensures that any technological adoption is not merely for the sake of novelty but is a strategic fit that will offer enduring benefits. To effectively manage differing opinions, we engage in open discussions, backed by data and case studies, to explore the pros and cons of each option. This analysis helps in making informed decisions that everyone can support, ensuring that our software not only meets current needs but also positions us well for the future.

Navigating conflicting opinions on software architecture involves fostering open communication, analyzing options, and focusing on project goals. Here’s my approach: 1.Encourage Open Dialogue: Create a safe space for all viewpoints. 2.Evaluate Options: List pros and cons, and rely on data and case studies. 3.Align with Goals: Ensure decisions support project objectives. 4.Collaborate and Compromise: Host workshops and seek hybrid solutions. 5.Seek External Input: Consult experts if needed. 6.Document Decisions: Clearly record the rationale and plan. 7.Iterate: Be open to refining the architecture based on feedback. This approach ensures balanced, well-informed decisions that drive project success

Be open to discuss different ideas and approaches. It's also important to take ideas and map them to the business requirements. Also discuss trade-offs that you would need to make for each approach. Some trade-offs would not be acceptable, which will help you eliminate approaches. It's also important to keep an open mind during discussions. You may have an unconscious biased towards a particular approach, but being an active listener will help you overcome that bias and move towards a better solution.

Bridging the Gap: Understanding Views in Architecture Decisions 1. Multifarious Viewpoints: Software architecture impacts various aspects (performance, security, scalability). Understanding each team member's perspective on these areas reveals potential concerns and opportunities. 2. Hidden Assumptions: Unvoiced assumptions can lead to disagreements. By discussing views, implicit needs and priorities come to light, fostering a more informed discussion. 3. Collaborative Solutions: By appreciating each other's viewpoints, the team can craft solutions that balance different priorities, leading to a more robust and well-rounded architecture.

Facilitar um ambiente de diálogo aberto é fundamental para resolver divergências na arquitetura de software. Permitir que todos expressem suas ideias sem receios é crucial. Reuniões regulares ou sessões de design são oportunidades valiosas para isso. Incentive debates respeitosos, focando nas soluções arquitetônicas e desafiando ideias de forma construtiva. Isso abre caminho para descobrir novas soluções e inovações.

One approach is to adopt an Architectural Review Board, consisting of High-Level Engineering leadership and the subject-matter experts. That said, those in disagreement should be open and receptive to contrasting opinions and ideas. Software Development is a "Team Sport", so listen, debate, compromise, and work TOGETHER on coming up with a solution (or solutions) that everyone can agree upon. Transparency and collaboration with your colleagues are key to a successful result.

There is no right or wrong choices but good and bad choices. There may be two or more good choices. So having a process to evaluate impact in helpful. Create a process what to evaluate and how do you compare two results. Some of the trade offs are consistency vs latency, cost vs availability, manageability vs maintainability etc. Take decision what is right for your team.

One Thing I've learned is that it's important to be aware of, what happens if something changes. Questions I find helpful for this, * Can we reverse the decision later without much impact? * What's the impact short-/long-term if we need to adapt/take it out again?

Navigating conflicting opinions on software architecture goes beyond just picking a side. Instead, focus on evaluating the impact of each viewpoint. Analyze how each proposed architecture affects the system's core qualities: performance, security, and maintainability. Consider how well they align with project constraints like budget and timelines. Most importantly, think about how each architecture can handle potential future changes and growth for the software. By objectively assessing these factors, the team can move beyond personal preferences and identify the solution that best serves the project's overall goals and long-term vision.

Entender os impactos de longo prazo de decisões arquitetônicas é crucial para o sucesso do projeto. É essencial alinhar cada opção aos requisitos, escalabilidade, manutenção e desempenho. Avaliar os riscos e realizar protótipos oferece insights valiosos sobre a viabilidade de cada escolha. Isso permite tomar decisões informadas que beneficiem o projeto como um todo.

I believe that having extensive career experience can help us assess different situations more effectively. When we had less experience, we tended to choose solutions quickly and efficiently, but we didn't always consider all the available options. It's important to thoroughly analyze the impacts of any decision on technology, architecture, and various aspects to make well-informed choices.

É essencial promover um diálogo aberto onde todos os membros se sintam à vontade para expressar suas opiniões e preocupações. Além de encontrar um terreno comum, é importante considerar a diversidade de experiências e perspectivas que cada membro traz para a discussão. Isso não só enriquece o processo decisório, mas também fortalece a implementação das soluções adotadas, garantindo que elas atendam verdadeiramente às necessidades e expectativas da equipe e dos stakeholders envolvidos.

Ao documentar decisões arquitetônicas, é essencial explicar a lógica por trás da escolha feita, destacando as alternativas consideradas e o motivo de não terem sido escolhidas. Isso garante que a equipe tenha uma referência clara e evita revisitar debates passados. Além disso, facilita a integração de novos membros e permite que todos compreendam o contexto das decisões sem depender de conhecimento prévio.

One process that team follow is to maintain Architecture Decision Records (ADR). These are simple 1/2 pager documents where the developer/architect need to record the reasons to arrive at a particular design choice, tradeoffs and maintainability aspects. ADRs serve as an excellent reference material while making changes in the future and reduces single point of dependency to make decisions.

When there is a choice between approach A and B, consider doing BOTH. The cost of endless debates might outweigh the cost of a light weight implementation of both approaches. This is rightly called AB testing. This approach is especially useful for making feature choices - not so for big architectural decisions. However, all big decisions can be broken into smaller ones and AB tested.

I would facilitate open communication and use data-driven evidence to guide our decisions. For instance, when my team disagrees on whether to use microservices or a monolithic architecture, we will conduct performance benchmarking and analyse scalability requirements, which may lead us to choose the microservices approach for its long-term benefits aligned with our business goals.

Always align the focus with what is/expected to achieve the OKR. Align it to the companies vision or the product goal. It helps in prioritisation and decision making

É importante considerar como as tecnologias envolvidas podem ser alteradas e mensurar o custo de troca das mesmas em cada camada do projeto, mesmo que a escolha pareça perfeita. Sempre considere que algo imponderável pode vir a acontecer: aquela tecnologia/abordagem que não dura o tempo que se imaginava, linguagens e IDEs que caem em declínio e por aí vai. Já sobre as opiniões conflitantes, cabe à pessoa que tem a responsabilidade (ou seja, que será cobrada em caso de falhas) ouvir todos os lados e considerar a vivência e experiência daqueles que estão falando. "Não havendo sábios conselhos, o povo cai, mas na multidão de conselhos há segurança." (Prov. 11:14)

We do envolve both business and technical stakeholders to make important decisions about software architecture in every project we made; and the end of the day, the project tecnical leader/lead architect has the ultimate word based in every point of view.
