  • Let me begin at the end This is the first and only great secret of architects worldwide
  • Everything is a tradeoff This course shall teach you Why “it depends” (and when it doesn’t matter much that – e.g. when you can you an off- the-shelf architecture like “3-tier” etc.) how to know what are the tradeoffs What to look for How to evaluate the impact of tradeoffs
  • Nobody is born an architect You usually start as a great developer Maybe then a lead developer I, for one, even moved on to project and development management And then one day you are nominated as an “Architect”
  • You need to understand implications of decisions and their long terms effects
  • I am experienced developer and designer – so now what? Isn’t that engough
  • Architect needs breadth of knwoledge (depth is always nice but you can’t have it all..) Design skill Patterns Anti-patterns Understand technologies Views Quality attributes analysis Business considerations Tools Software life-cycle Softskills communications leadership organizational politics etc. Etc.
  • Columbos Alan Dershowitz At the age of 28 he became the youngest full professor in Harvard law school history Successfully defended high profile clients O.J. Simpson Claus von Bülow Frank Lloyd Wright Frank Lloyd Wright ( June 8 , 1867 – April 9 , 1959 ) was one of the most prominent and influential architects of the first half of 20th century . He not only developed a series of highly individual styles over his extraordinarily long architectural career (spanning the years 1887-1959), he influenced the whole course of American architecture and building. To this day he remains probably America's most famous architect. (wikipedia)
  • 2003 PSS Global Summit Software architecture is the collection of the fundamental decisions about a software product/solution designed to meet the project's quality attributes (i.e. requirements). The architecture includes the main components, their main attributes, and their collaboration (i.e. interactions and behavior) to meet the quality attributes. Architecture can and usually should be expressed in several levels of abstraction (depending on the project's size).   If an architecture is to be intentional (rather than accidental), it should be communicated. Architecture is communicated from multiple viewpoints to cater the needs of the different stakeholders. Architectural decisions are global tied to quality attributes Designs decisions are local –tied to functionality Every system has an architecture, even if it is not formally “spec’ed out”.
  • To deal with the size and complexity : Scale Process Cost Schedule Skills and development teams Materials and technologies Stakeholders Risks Somebody has got to balance the (conflicting ) requirements
  • Here’s a definition Don’t bother to remember it Because… What’s important is that It is there

    8. 14. The Tao of Software Architect The architect doesn't talk, he acts. When this is done, the team says, &quot;Amazing: we did it, all by ourselves!&quot; (17) The architect observes the world but trusts his inner vision. He allows things to come and go. His heart is open as the sky. (12) By Philippe Kruchten -
