Krachten in de informatievoorziening

In zijn beroemde werk waterval, laat Escher de kijker denken dat water omhoog kan stromen. Zoals we echter weten moet water, net als alle andere materie op aarde, gehoorzamen aan de natuurkrachten. Met de huidige wetenschap zal water in de werkelijkheid altijd omlaag stromen. Zelfs beroemde ontwerpers als Dyson, bekend van de stofzuigers zonder zakken, moeten zich daar bij

"The way" to Enterprise Architecture

2007-09-06T23:00:00+00:00

Research indicates that the most effective IT governance approach is a federative approach. In this approach, IT guidelines are developed at enterprise level but the actual IT decisions are made decentral. The pure centralised model however appears to be more popular, but less successful. In an article about "Lessons from Iraq and Katrina", Bill Hall states that "From the organizational

Behaviour is everything

Many architects put a lot of effort in rationalising the process of architecture decision making. These rational approaches to decision making typically break down in two stages: the problem identification stage and the problem solution stage. The idea behind the rational approach is that decision making follows a systematic method of logical reasoning steps that - if performed correctly -

Collaborative architecting

To date, architects very often operate as soloists. Soloists with a knowledge of construction paradigms, patterns, technologies, methods, etc. But as the construction space keeps expanding, the required knowledge is increasing: technology stacks and tiers are added, construction techniques evolve, the line between off-the-shelve and bespoke development is fading and reusable services are becoming commodities and their number growing

Creativity as strategy

2007-01-14T00:00:01+00:00

The importance of creativity as a strategic competence is growing rapidly; it is key to survival in the next era. Creativity is not limited to products and services but also to the way value chains / networks are structured and the nodes (partners) in the network are implemented. Technology will penetrate deeper and deeper in the execution and will

Business driven architecture

Applications get more and more detached form the infrastructure they are running on. The same goes for the architectures of both. In the most extreme scenario, architectural design choices related to the infrastructure are made completely independent from the applications running on the infrastructure. For applications, the infrastructure in most cases is a given. One could compare the relationship

Residue based intelligence

The future will bring more and more surprising products based on the reuse of digital 'residue'. These residue based products are products created on the residue of other products. To illustrate let me give you some examples:
- mobile phone positioning data (a residue mobile phone users leave when then are linked to the network) to calculate car

Free modeling tools

2007-02-18T00:00:00+00:00

Often the best way to express a design is by means of a visual model. There's quite some modeling languages around, to name just a few: Archimate, UML, BPMN, EPC, IDEF, Use case maps, E3value. The complexity of the average language (an important improvement area) forces the architect to look for a tool to support his modeling effort. Architects
