Top challenges with integrating EA and App Architecture

Top challenges with integrating EA and App Architecture

- lack of common understanding of disciplines
- gaps and overlaps b/c of unclear responsibilities
- disruptions of risks and opportunities
- hard to attribute success of the whole among the parts

Gartner’s proposed definitions

EA - strategic view; what new biz capabilities will be needed; enterprise vs local solutions
Enterprise Solutions Architecture - enterprise shared solutions
App Architecture - How to build proposed solutions across the portfolios
Solution Architecture - builds and enhances business capabilities; execution oriented

EA is a discipline and delivers value by presenting business and IT leaders with signature-ready recommendations

EA addresses the evolution of legacy applications and meets the new demands of web-centric, process-oriented, event-driven, highly distributed or cloud-based systems.

EA - delegate and coordinate; inform and empower; few critical standards and more guidance; be willing to NOT be the SME

App Arch - leverage and promote best practices for Solution Arch; recognize the power of collaboration; ask for line-of-sight reasoning; look for future state guidance

Cultural Change
- fight the not-invented here attitude

Recommendation - agree on definitions, objectives and approach for how the disciplines should interact

Quadrennial Energy Review - Jan 2017 (notes) "The electricity system we have today was developed over more than a century and includes thousands of generating plants, hundreds of thousands of miles of transmission lines, distribution systems serving hundreds of millions of customers, a growing number of distributed energy resources, and billions of enduse devices and appliances. These elements are connected together to form a complex system of systems." "The electricity sector is, however, confronting a complex set of changes and challenges, including: aging infrastructure; a changing generation mix; growing penetration of variable generation; low and in some cases negative load growth; climate change; increased physical and cybersecurity risks; and in some regions widespread adoption of distributed energy resources

The End of Solitude - Response to William Deresiewicz

I recently read an article by William Deresiewicz titled “ The End of Solitude ”. What prompted me to read the article was an interview with Mr. Deresiewicz that I heard on NPR. During the NPR interview, Mr. Deresiewicz delved into the importance of solitude, being alone and time for self-reflection. Of course, you are naturally drawn to premises that are similar to your own so I listened intently as he contrasted the present with the past regarding the lack of “alone” time that we all face today. Mr. Deresiewicz’s literary knowledge is beyond impressive – he’s an academic and is able to compare and contrast numerous thought-leaders of the past and their views of the value of solitude.

My personal appreciation for Thoreau’s writing, specifically Walden and more specifically “Solitude” and “Economy” immediately came to mind as I read
