No matter if you are an organization of 3 employees or a company of 1000 plus, giving employees the proper tools so that they may complete their daily tasks is an essential part of business. AND it is an essential component of branding. In the absence of tools and process, employees will take it upon themselves to get a task done, no matter how. We should not fault them for this.
Instead, provide them EVERYTHING they need to get their job done and to build the brand correctly and efficiently. Providing guidelines, assets and templates for everyday tasks is a common sense approach to building a great brand, especially in a climate where marketing professionals are wearing multiple hats and inundated with menial tasks that do not move the brand dial. Give power to the employee to use the brand correctly. Hold them accountable. Branding is a process and everyone has their part, so educate and evolve.
