This study will make an effort to discuss several business decision-making tools and strategies. Mathematical tools including statistical, financial, accounting, and management accounting methodologies will be used to discuss the fictitious scenario of business decision-making. The intense competition and capitalism that characterise today's corporate climate make it far more unstable, unstructured, and unpredictable. Management must occasionally or daily make diverse decisions. As a result, they must employ methods and instruments that are advantageous to them. We will employ some extremely prominent and popular decision-making tools, particularly statistics and finance, to make decisions that are more realistic, nuanced, and time appropriate. These methods will be important to B&W PLC's decision-making processes.
