In today's commercial environment, understanding elements of a contract is crucial. Twomey (2010) emphasizes that business law principles are essential for commercial success. Similarly, Zoll (2012) highlights the binding power of contracts, particularly in the Common European Sales Law context. According to Oxford University Press, a contract requires certain essential elements, including offer, acceptance, and consideration. Furthermore, improper understanding of roles and responsibilities can lead to negative factors like poor coordination among treatment procedures. Effective communication is also vital for company success, as it directly impacts team members' ability to interact internally and externally. Therefore, understanding contractual principles, such as those provided by Twomey (2010) and Zoll (2012), is essential for businesses in the twenty-first century.
