Business Models and Operating Models
(This reading is assembled from blogs at ashridgeonoperatingmodels.com)

What is the difference between a business model and an operating model and who cares? First, I don’t think that it matters how you define terms like business model or operating model or business architecture. But it does help to be consistent. In this blog I will offer some definitions, not because I think they are more right than other definitions but because, in order to develop definitions, you need to think through all the moving parts.
For me a business model is the larger concept. An operating model is a part of a business model. An operating model is the engine at the heart of the business model that helps make the business model work.
A business model defines the following
- the stakeholders with whom the organisation will interact
- the offer or promise that the organisation is making to each stakeholder segment
(customers, employees, investors, suppliers, etc both internal and external)

The State of Smartphones in 2013: Part I of the new Ars Ultimate Guide


Enlarge / More phones than you can shake a phone at.
Andrew Cunningham

It's been just under a year since the last time we examined the state of the smartphone. The intervening months have brought us the expected annual hardware refreshes and software updates, but it's striking just how similar things are at a high level.

Apple and Samsung are still standing at the top of the field, and at the moment there's not a strong third-place contender in sales or in reach. HTC continues to be down on its luck despite the critical darling that is the HTC One. LG is still taking pages from Samsung's playbook, trying lots of odd ideas in an effort to differentiate. Microsoft is still struggling to improve Windows Phone 8's standing with consumers, developers, and hardware partners. All of this is more or less as it was a year ago.

OS X 10.9 Mavericks: The Ars Technica Review

Aurich Lawson / Thinkstock

After a dozen years and nine major releases, OS X has had a full life: the exuberance of youth, gradually maturing into adulthood, and now, perhaps, entering its dotage. When I am an old operating system I shall wear… leather?

The 2011 release of OS X 10.7 Lion seemed to mark the natural endpoint of the "big cat" naming scheme. But Apple couldn't resist the lure of the "cat, modifier cat" naming pattern, releasing OS X 10.8 Mountain Lion a year later. Perhaps it just wanted to give its cat nine lives.

The 10th major release, OS X 10.9 Mavericks, is named after an awkwardly plural California surfing spot, finally ending the feline dynasty. But what part of the operating system's existence is this? The afterlife?
