Excel can play an important role in decision-making by allowing users to perform quantitative analysis, model different scenarios through "what-if" analysis, and leverage large amounts of organized data. Users should consider their goals, requirements, and limitations when building spreadsheet models. Both quantitative and qualitative factors can influence decisions, and having either too much or too little information available can potentially impact outcomes. Problem-solving and decision-making are related processes, with problem-solving informing the identification and evaluation of different choices.
