When you are involved in a conflict and want to resolve it, you often have two options: informal resolution or formal resolution.
Formal resolution processes include things like grievances or lawsuits. They usually require you to submit your complaint in writing and provide evidence or testimony, which is then considered by the appointed decisionmaker(s). Generally the outcome is a written decision, which you may (or may not) have the ability to appeal. All of this usually takes place within specified deadlines. In a formal resolution process, you get to present your complaint, but you don't get to decide the outcome.
Informal resolution is less focused on the process and more focused on the outcome. Rather than taking opposing sides, the parties work in a collaborative fashion to try and achieve an outcome that is mutually acceptable. The parties themselves take responsibility for developing the outcome, rather than giving that task to an uninterested decisionmaker (like a judge). Mediation is one type of informal resolution process.
