When recently I moved from banking to the public domain, I found with surprise that UK Government is currently focusing on “#shared #services” (#ShaSer) while this topic had been addressed in banking for a decade, at least, ago. So, what the heck is ShaSer? Wikipedia states, “Shared services is the provision of a service by one …

⌗ARCHIMATE TRANSFORMES ITSELF INTO LOREM IPSUM
For the last 2.5 decades IT architects used Unified Modelling Language (UML) notation. This graphical notation and the concept supporting it was created by Grady Booch, Ivar Jacobson, and James Rumbaugh while working at Rational software. In 1997, the Object Management Group (TOG) adopted UML as a standard for its members,. Later on, UML became a …

A short-term tactical solution may be good only if you have the long-term solution observed/understood already
During a recession, every company faces a dilemma – where to put its management attention and funds – in the short-term surviving projects/products or the long-term ones as well. IMHO, if you are concerned about survival only, you will lose immediately after the recession ends even if you survive it. My advice is to put …
IF EXPERTS STILL DEFINE EA DIFFERENTLY, WHAT IS EA ACTUALLY?
I am thankful to Capstera Software for collecting several different definitions of Enterprise Architecture (EA). This variety, which I will discuss today, raises a flag of the immaturity of the term, including concerns about whether it is about enterprise as a whole as well as whether it is about architecture (a standardised term by IEEE) …

DevOps are not enough
Induction I’ve read somewhere that the major criterion of DevOps work is running code. If DevOps is engaged in the creation of products for consumers, just running code is not a criterion – it is not enough. There are, at least, two requirements – the code must deliver the value it has been written for …

How smart is #Smart #Contract?
The first time I heard about the automation of contract negotiation and agreement in 2001-2002. It was written in ebXML (backed by OASIS and UN/CEFACT). It was an amazing achievement because the first SML Conference took place just in 2001. The endeavour fails because of two major reasons, as I learnt later: Recent splash of …
Jeopardy of an API Economy
2015 Why I am moving against the flow again? Why all around are getting excited about APIs and I don’t? Probably, this is because of negative post-taste after DOT-COMs and global webinisation of industry 15 years ago when the most sensitive information was offered to anyone, including competitors and simply not good people or it …
No Need to Sell Business Architecture to Executives
2015 Currently, there is a lot of discussions in the industries about Enterprise Architecture (EA) and Business Architecture (BA). An Enterprise Architecture rooting from IT is fairly denied by the corporate business as not competitive yet. However, we know multiple cases where IT Enterprise Architects (EAs) were held aside from the business concerns of the …

#Updated #Principles of #Service #Orientation
2014 Motivation Current Principles of Service Orientation (SO) were formulated about 15 years ago when Service-Oriented Architecture (SOA) fought its way up into the mainstream of enterprise IT. They are widely known from publications of Thomas Erl 1,2 where the vocabulary of SO was compromised for the sake of mass adoption of Web Service technology. …

#Purpose #Case #Management and #Solution #Flexibility #Estimate
2012 Preamble After many years of process-dominating approach to our work, we have collectively “discovered” that the process is not the only way of doing things. There are many unstructured activities and even social activities that have to be governed and managed. These activities affect our daily productivity and, at the end, an efficiency of …

UML between Top-Down and Bottom-Up
2014 During holidays very strange and different thoughts come to mind. For example, when we use UML in project design for development, what is the difference between a top-down and bottom-up design? Ok, let’s start with the simple case. As we know, traditional UML operates with Class as the basis element. The latest 2.4 and …
