IT Governance & Enterprise Architecture – The Yin and Yang of IT

IT Governance and Enterprise Architecture like Yin and Yang are complementary concepts that interact to form a dynamic system in which the whole is greater than the assembled parts.

Data Warehouse Architecture Best Practices

A data warehouse should consist of at least three layers. You could design each of these three layers with several individual sub-layers.

Those three layers could be named Staging, Core and Access but several other names could be used as well like Landing, Sourcing, Integrated, Enterprise, Analytic, Application, etc. After all, they are just names.

In addition to the three layers, other components could be useful like a data lab, and “big data”, as well as support for advanced analytics.

Access Governance - a step towards better information security

Could your documents have turned up on WikiLeaks? If you do not have complete control over user access rights, the answer is YES.

With just 500 users, 100 systems and 100 folders there are potentially a quarter million user access rights to keep track of.

I have a dream

of a society where people focus on relations and innovation – and leaves administration to systems.

IT - not just a cost

Many mistakenly consider the entire IT budget as a cost.

This is by no means the case! A very large proportion of IT spending should be viewed as investments, even if it for taxation purposes is considered as expenses.

IT Governance for Mergers & Acquisitions

The first and probably most important prerequisite for a successful merger or acquisition is that you have a complete and well-defined future brand and value proposition for the resulting company. Next, you should perform a thorough due diligence process, not only looking at financial and contractual obligations, but also at the enterprise architecture focusing on business processes and the application portfolio, maybe with even more scrutiny.

Digital natives entering the job market - What will happen?

Digital natives, a term coined by Gartner Group for the generation that has grown up using all sorts of IT devices from a very young age (probably before the age of 2).

The digital natives are now entering businesses. This will change a lot.

Will CobiT help me with cloud-computing?

Yes, certainly CobiT can help with cloud-computing.

CobiT is an IT governance framework and particularly two processes "Define a Strategic IT Plan (PO1)" and "Manage Third-party Services (DS2)" will give guidance on what you should do before and after selecting a cloud solution, how you could measure and monitor the value you gain as well as your risk exposure and who should be responsible, accountable, consulted and informed during the effort.

All systems in the cloud

Cloud computing is hot!

A lot of companies are now investigating how to place software in the cloud i.e. outsource it.

Before I tell you what I think of this let me just describe the reason for having software in the first place.

Business People vs. IT decisions

In my opinion!

Business people must take responsibility for the requirements related to the business processes they want supported by an IT solution, the information flowing into/out from the solution, and the information to be stored by the solution.
