This blog is written by Samuel Kaluvuri, Founder and CEO at ApyHub (providing Next Gen Utility APIs for developers). He has extensive background and expertise in the realm of software architecture, and experience in using design flexibility as a framework when leading engineering teams.
Software architecture serves (and has served) as the main pillar for all the cutting-edge software we are aware of today. Part of my role in many startups has been to design and architect software that will in some way, change the way people and businesses interact with each other.
What I find very exciting when it comes to software architecture, is how drastically it can change the way a whole product performs, how some seemingly tiny changes or adjustments can make a huge impact to how software is packaged, delivered and experienced.
While software architecture sets the foundations for software design by defining the key components, their responsibilities and the communication that happens between these components, software design takes these architectural decisions into account and applies them to data structures, algorithms, modules, classes, interactions among others.
One of my favorite concepts and ideas around architecture is design flexibility and its connection with unleashing developer creativity and flexibility. Ultimately, architecture should be about creating software systems that are not only adaptable but also foster innovation.
Designing a product or a system can be complex and requires careful consideration of several factors besides the architectural guidelines. And while there are many approaches to designing systems, these approaches can be grouped broadly into categories: structured design and flexible design.
Structured design tends to be a top-down approach that follows a set of rules and guidelines from most of the requirements that are gathered upfront. While a flexible design approach is more open ended and evolves from a minimal set of requirements that are known upfront and allows for experimentation and adaptation over time.
Structured design is an important aspect for products and systems in critical and sensitive domains (like healthcare, aviation etc), however, in other non-critical domains design flexibility tends to be a better choice in the long run. With structured design, developers are limited by the set of predetermined rules and guidelines that can stifle creativity and limit innovation potential. Structured design may seem like a cost effective approach at first, but it can lead to costly mistakes or redesigns overtime.
Flexible design, on the other hand, allows designers to explore new ideas and approaches that can often lead to breakthroughs and advancements that would not be possible with a more rigid approach. Flexible design also is an ideal fit for a rapidly evolving world, where markets and consumer preferences change often. Structured design often deals with the needs of the majority and when a user or a minority of the users have a specific need it is not easy to change the design of the system to accommodate their needs. However with a flexible design approach, developers can easily adapt their systems and products to cater to the needs of their users leading to greater loyalty and satisfaction with the product.
Both structure design and flexible design have their benefits obviously. However, I believe that design flexibility is a better choice in the long run (for non critical domains) as it allows for innovation & creativity, adaptability to change and cost effectiveness.
