Unlocking Enterprise systems using voice

All Things Distributed

The interfaces to our digital system have been dictated by the capabilities of our computer systems—keyboards, mice, graphical interfaces, remotes, and touch screens. As a result, they fail to deliver a truly seamless and customer-centric experience that integrates our digital systems into our analog lives. All of these benefits make voice a game changer for interacting with all kinds of digital systems.

The challenges of monitoring a distributed system

Particular Software

I remember the first time I deployed a system into production. Once the system was deployed, I wanted to see if everything was working properly, so I ran through a simple checklist: Is my database up? Yes/No) If the answers to these questions were all yes, then the system was working correctly. If the answer to any of those questions was no, then the system wasn't working correctly and I needed to take action to correct it.

Corporate Middle Management as an Autopoietic System

The Agile Manager

[T]he aim of such systems is ultimately to produce themselves: their own organization and identity is their most important product. -- Gareth Morgan, Images of Organization , p. This is in contrast to allopoietic systems, which use components (raw materials such as silicon and plastic) to generate something (mobile phones and computers) which are distinct from the thing that created it (the factory where they are made). The system thus organizes its environment as part of itself.
