What Pragmatic means in Software Architecture?

We are currently in the world of rapid software development using agile methodologies where fast and frequent delivery of software is paramount. This is done through 2 week sprints providing customers opportunity to view and provide feedback on the software as it gets developed.

This definitely brings in the discussion around how much architecture work needs to be done before or whether it needs to be carried out during the Sprints? In my experience I would always recommend a Sprint 0 which provides ability to do enough Architecture to get the Development team understand on the technical aspects of the software to be developed and reviewing them as part of the Sprints so that what was proposed got delivered.

Understanding what is really required for the Development team to get started is what I think being pragmatic. This will avoid doing too much upfront design or doing nothing.

  • P: Promote collaborative work that involves all team members
  • R: Reduce risks and uncertainties
  • A: Adhere to minimalism and simplicity principles
  • G: Gather key elements to outline the architecture during your initial timed-boxed iteration 
  • M: Modify the design throughout the development life cycle to adapt to emergent needs 
  • A: Address both functional and non-functional requirements
  • T: Try out theoretical concepts and leverage past empirical experience
  • I:  Invest in known requirement instead of hypothetical future needs
  • C: Concentrate on tasks that support the development team

Architecture diagram using Visio Stencils

Image
In the previous post, I emphasised on how much a picture can communicate than words. In order to draw good Architecture diagrams using Visio, first we need the proper stencils. The following stencils would be handy for any Architecture diagrams using Visio. Office Stencils Microsoft Azure, Cloud and Enterprise Symbol / Icon Set Azure Reference Architectures Microsoft Integration Stencil Pack Exchange 2013 Stencil SOA Stencils (from Arcitura) ( Symbol Legend ) Cloud Computing Stencils (from Arcitura) ( Symbol Legend )

The Death of the Architect

I just received an email with this subject line and got curious and started reading it immediately. ( https://dzone.com/articles/the-death-of-architecture?edition=347143 ) Though I agree with some of the points in the article but I don't agree the fact that Architect role is disappearing. With Cloud computing, I personally feel the responsibilities of an Architect has increased. There are far too many options and ways of addressing the problem using Cloud Solutions and that's when you need a Pragmatic Architect. I completely accept the fact that we don't need Ivory Tower Architects and we need Architects who definitely knows writing code and be part of the Development team ( https://www.infoq.com/articles/architects-should-code-bryson/ ). The Architect must know when to assist the Development Team with coding activities and when to focus on Architecture activities. Pragmatic Architect knows how to balance this quite well and they earn respect from the Development Teams.

Communication skills for an Architect

Communication Skill is a key skill for a Software Architect. An Architect need to communicate to different set of audiences starting from C-level Executives, Business Stakeholders, Subject Matter Experts to Software Developers. They have to communicate the solutions in different ways to different audiences. Normally this takes time and comes by practice and experience. The Architect must also be capable of communicating their points with clarity so it is easy to understand for the rest. There is no point in writing pages and pages of architecture documents instead how it can be communicated to the team is really the value added. "A picture is worth a thousand words". Therefore try and communicate your ideas in diagrams. These diagrams can be in Visio or even a white board drawing as long as it can convey the message.
