The Ultimate EA Picture

Gideon Slifkin, Global Architecture Lead at Deloitte shares his perspective of Enterprise Architecture through his LinkedIn posts. The recent discussion sparked by his post on 'The Ultimate EA Picture' makes for interesting reading.

EA is broad




According to Slifkin, “The” EA is a collection of various artifacts, Blueprints, Tech Standards, Reference Architectures - all sorts of things really - which collectively can be thought of as “The EA.”

The following collectively make up “The EA”:

1. Architecture (ie current, future, roadmap) for each Business Portfolio / Segment / Value Chain (as appropriate) focusing on the Business Capabilities, Business Processes, and Applications / Data and Integration 

2. Architecture (ie current, future, roadmap) for each Technology Domain / Segment / Platform (as appropriate) focusing on Technology Capabilities, Use Cases, Tools and Platforms etc

3. Architecture (ie current, future, roadmap) for each Business Application / Technology Solution (as appropriate) focusing on all architecture domains for that Solution

4. Any relevant Technology/ Architecture Standards, Guidelines, Best Practices, Principles etc (though this can get debatable e.g. Are backup guidelines really part of EA?)

5. The EA Repository - though that could be included as the digital representation of 1,2 and 3 above

6. Reference Architectures and Design Patterns - not exactly “The EA” but close enough conceptually

7. Standard “Components” and/or Services (if not already included in 1,2, or 3 above)

8. The Enterprise Business Architecture for Business Strategy, Goals, Operating Model etc (if you believe that's all part of EA)

Enterprise Architecture is the comprehensive, integrative discipline dedicated to orchestrating the connective tissue of the organization—bridging the critical spaces between discrete events and intended outcomes, between present realities and envisioned futures, and among the structural components that underpin the enterprise. It achieves this by curating institutional knowledge, catalyzing cross-functional collaboration, and illuminating systemic patterns that empower leaders to make strategic, evidence-based, and value-centric decisions.

Kai-Fu Lee on China-US AI Race - Q&A Transcript from a Bloomberg Interview

Kai-Fu Lee, Chairman of Sinovation Ventures and author of  AI Superpowers and  AI 2041: Ten Visions for Our Future on the China-US AI Race Q: There's still a lot of challenges when it comes to the whole monetization of AI, according to his perspective. In the last three years, though, how have you looked at this whole evolution of China AI versus the US, and what are the advantages and challenges for China? A: Yeah, so firstly, I disagree on the prospects for the USA. USA because yes, you look at OpenAI, it's making half billion spending 40 billion. It looks like a bad balance sheet, but most of that 40 billion is spent for future revenues. And if you believe there are 2x, 3x, 5x growth for the next three years, it's going to justify that valuation at some point. The bubble is merely that it's gotten ahead of itself, not the likelihood of growth in the future. Not saying it's worth its price, right, but there's absolute substance under the thumb. Now back to t...

The Mercurial Grok AI Assistant Understands & Speaks Indian Languages

Image
Grok , the AI model developed by Elon Musk's xAI, can understand when you type Indian languages like Hindi, Telugu, Odia or other Indian regional languages using English letters (like when you type 'namaste' instead of 'नमस्ते'), and it can respond by mixing English with those languages. Grok doesn't necessarily need the native script of these languages. It has natural language processing abilities that extend to multiple languages. This is great innovation because many people in India, especially in online communication, use transliteration. Grok can generate responses that combine English words and phrases with words and phrases from the regional language you used in your input. For example, if you ask a question using a mix of English and Telugu transliteration, Grok might respond with a sentence that includes both English and Telugu words. Check these Hindi, Telugu, Odiya samples - Grok, ab Hindi mein Grōk, ippuḍu telugulō Grok, Oḍiā re This way Grok is more...
