Welcome to R&A

For the Board: Essential Reading on IT Strategy

IT is notoriously hard to manage and it has been so for decades. As a result, the execution of new strategies is often exceedingly difficult. These 4 articles (2 serious, 2 a bit tongue-in-cheek) are meant to enlighten non-IT-savvy board members.

Key posts on IT

(What I consider to be) my key articles on (governance and fundamentals of) IT and EA in general. Easily accessible from here.

Let’s bury NIST’s outdated definition of Cloud Computing

The NIST definition of Cloud Computing from 2011 has now become so much an oversimplification that it is more often than not unhelpful, e.g. when trying to base your policies on it.

So, forget about ‘IAAS’ and ‘PAAS’, end your ‘cloud policies’ or cloud-specific procedures. Instead, concentrate on managing the key generic issue underlying it: the ever more complex mixes of owned and outsourced algorithms and data, regardless of oversimplistic ‘cloud’ concepts.
