When implementing a new process or strategy, it's common to use the phrase "introduce a system." However, sometimes it's helpful to mix up your language and use synonyms to keep your writing fresh. Some alternative phrases include "implement a protocol," "roll out a procedure," "instigate a method," or "propose a framework." Additionally, you could use more specific terminology such as "install a software system," "establish a workflow," or "create a guideline." Using various synonyms not only elevates your writing but also helps to distinguish between different processes and strategies, making it easier for your audience to understand the specifics of what you're discussing.
