The influence of competitor knowledge on business decision making

The influence of competitor knowledge on business decision making

In 2022, we’ve reached a time where the on- and offline competition is bigger than ever, a time when everyone can join the race. And so it is crucial to get an understanding of your competitors and the position your business holds within the industry. Because of that, the first step is choosing the right competitors based on a variety of elements that make them relevant to your business. It would be most obvious to look a the products or services they sell, right? However, the technology they use, their business model, target audience, and marketing channels are also relevant. Based on these criteria, you can conduct various analyses to study and compare your strategy.
