What are some common solution design principles and how do you apply them in your projects?

Understand the pain areas , do proper pilots , do iterations, use collaborative tools .Priorities the requirements , do proper valuation , assessment.

Understand the big picture and discover the root of the problem along with the current impact and potential value. Manifest the key areas of evaluation criteria which will guide us in the selection of design and build trade-off parameters.

Analysing the subjective problems and then break them into quantifiable and actionable objective outcomes is paramount. Defining the parameters for success for a long term implementation and then pre-empting for issues 2-3 years down the line is absolutely crucial.

The Primary step of Solution Designing is to understand the requirement or to be more elaborate the problem underlying in the requirement. Next step is the prioritizing of the requirement and choosing the best methodology and principles.

Here are some strategies to consider: 1. User Research and Feedback 2. Iterative Design and Prototyping 3. Educational Resources for Users 4. Simplify the User Interface 5. Accessibility 6. Cross-Platform Consistency 7. Leverage Analytics 8. Stay Updated with UX Trends 9. Expert Consultation Consider consulting with UX experts who have experience integrating new technologies into mobile apps. Integrating new technology into your app’s UX design requires a balance between innovation and usability. By focusing on user feedback, simplifying interactions, and providing educational resources, you can enhance the user experience and ensure the successful adoption of new technologies in your app.

This high level solution must be cohesive and open for future integrations with different/new unknowns. For example, the same microservices architecture is connecting to different channels like UI/UX, Batch & mobile handhelds, might be backed by API gateway & Authentication server, connecting to OLTP/OLAP SQL/No-SQL databases, interacting with Big Data, interacting with many in-house/out-house services etc. Also this flexible solution must be allowed to tune up the non-functional requirements (NFR) time to time. As we know any product become GA (general availability) after alpha & beta cycles.

When selecting architecture, prioritize modularity for flexibility. Embrace microservices if scalability is anticipated. Opt for simplicity, ensuring clear designs. Choose adaptable architectures and promote component reuse. Maintain clean and manageable code. Early performance considerations are crucial, ensuring optimal system responsiveness. Prioritize security measures. Opt for architectures compatible with other systems, emphasizing interoperability through APIs. Mindful cost management ensures staying within budget and resource optimization. Following these principles guarantees an architecture that aligns with the project's requirements.

Applying design patterns can significantly enhance the overall coherence and foster seamless interactions among components, leading to a more robust and scalable architecture. However, it's crucial to choose the right patterns for the specific context and consider their potential drawbacks. For example, in event-driven systems, the Observer pattern can promote loose coupling and flexibility, but it can also introduce additional complexity if not used right.

Principles like KISS and SOLID collectively advocate for clear, concise, and straightforward design practices. Prioritizing simplicity ensures that the architecture is crafted to be easily understood, adaptable, and maintainable throughout its lifecycle. This commitment to simplicity aligns with the overarching goal of creating resilient and successful systems that can seamlessly evolve with changing business requirements.

Using adaptive approach, like scrum can help us to validate and refine the design and also real requirements of stakeholders. the main idea behind adaptive approaches is that you use a "backlog" of prioritized tasks that should be done (Based on requirements and priorities of the product or solution owners). the team works on some tasks with highest priority in an iteration. after finalizing an iteration, they check the works have been done, comparing it with product roadmap, prioritize the requirements again and refine the "backlog" and starting the next iteration.

Adapting to change is very critical , ensure proper adaption of feedback , review proper mechanisms and tools , do various pilots .

I think continuous and effective communication with stakeholders is missing. without considering stakeholders, their power to influence on the solution and impacts of the solution on them, our solution will not be successful. we have to devise an optimal and effective approach to manage effective communication with stakeholders. stakeholders are the people who impact, be impacted or even perceived to be impacted by the situation.
