This is done so as to not eliminate important alternatives until the last possible moment i. A strategy of not making a premature decision but instead delaying commitment and keeping important and irreversible decisions open until the cost of not making a decision becomes greater than the cost of making a decision. One way to mitigate the risk of deciding too late is to build Proof of Concepts POCs to prototype the alternative options and demonstrate to the stakeholders what they are asking for.
This is an amalgamation of the five principles we elaborated on:. I hope this article is a source of inspiration and guidance in your architectural journey. Here are some good resources if you would like to find out more on a few of the subjects we covered:.

We will now see how… Single Responsibility Principle Each system capability e. Open-Closed Principle This principle postulates that it is preferable to extend a system behaviour, without modifying it.
Single Responsibility Principle
Dependency Inversion Principle High level modules should not depend on low level ones; they should both depend on abstractions. Least effort is a variant of least work. The principle of Opportunity Cost Every time we make a choice, there is a certain value we place on that choice.
It is challenging enough to come up with one solution, let alone a few! What is the product pipeline for the next 1—3 years? And what other projects are lined up? Can you see any synergies?
Software Architecture: The 5 Patterns You Need to Know
What is your current technical debt that you could potentially address? And turning this around: How much new technical debt will incur if you pursue a tactical solution? Which quality attributes tend to be the most important for systems in your organisation and how will they be compromised by the proposed solution? Apart from the architecture team who else is a stakeholder that will affect the decision?

The Business? Your boss? The Technical Design Authority? What are the key objectives of each stakeholder? How will you mitigate conflicting needs? The principle of Last Responsible Moment This principle aka Cost of Delay originates from Lean Software Development and emphasises holding on taking important actions and crucial decisions for as long as possible. Towards Data Science Sharing concepts, ideas, and codes.
City girl with passion in software engineering; lover of iced coffees, witty words and elegant systems — Opinions are my own; often flawed! Towards Data Science Follow. The book is also suitable for use in undergraduate and graduate-level courses on software and systems architecture as it exposes students to the concepts and techniques used to create and manage architectures of software-intensive systems.
Raghvinder Raghu Sangwan is an associate professor of software engineering at Pennsylvania State University. His work involves design and development of software systems, their architecture, and automatic and semiautomatic approaches to assess their design and code quality. He has published several papers in these areas. Prior to joining the Pennsylvania State University, Raghu was a software architect at Siemens, where he worked on large-scale systems in the domains of health care, automation, transportation, and mining; many of these systems were developed by teams geographically distributed around the world.
