The greeks came up with strategy. They even came up with the word strategy (stratēgia, from stratēgos). Sure, they are having a hard time convincing anyone at the moment that they are any good at it, but that's beside the point.
Everything strategic began with the Greeks, or at least, the Greeks were the first to put strategy into boxes and models we can all comprehend. Everything since is an adaptation on the original. We are copying them and we don't even realise. It's hard to come up with anything truly original these days. Ever tried registering a domain name?
If you feel like embedding some strategic models in your organisation (or for that reason, maybe you are eying off a table or even a matrix thinking template) just use it. You don"t owe anyone anything. You might like my strategic overview model. I didn't come up with it, but I have used it many times, find it extremely useful and I"m able to adapt and customise this model for each client I work with. If you like it, copy it, steal it. After studying a number thinking methods and case studies, I came up with the Dual Cycle Model, you can steal that too if you like. I didn't copy it, but I'm sure someone has come up with something similar before.
If you're thinking about your brand identity and positioning, you might be tempted by the many models that exist. Some are circles, some hexagons, or even rhomboids. If you are going to steal a process for this however, why not go with the original (or email me for a template...I stole their ideas and put them into a neat little box). It isn't even that original.
It's not the size of the model, nor how modern it is, it's how you use it. And that is the key. Thinking models are great, for helping you think. But they are nothing without the thinking part. What's the point in stealing a Ferrari if you don't know how to drive it, and is a Ferrari even right for your company? Maybe a VW beetle is more your style.
