Introduction Many organizations like to measure their compliance level against certain standards even without any legal obligation. This process is known as pre-assessment audit, which is used by many organizations as a tool for evaluation and learning to help in the improvement of the management systems. Through this process, the management will identify all the areas that need improvement. Organizations are also required to carry out pre-assessment audit before they can receive the credential of certification. Pre-assessment audit is part of internal audit where organizations are required to evaluate their management systems as a way of ensuring that there is good corporate governance. This paper will analyze procedures for pre-assessment audit and internal audit using the case of National Bank of Abu Dhabi (NBAD). The bank is ranked the best financial institution in the Middle East and it was awarded standards for quality management ISO 9001-2008. Procedures for pre-assessment audit Pre-assessment audit involves a number of steps which organization ought to follow for a successful process and certification by the registrar. These steps include Commitment of the top management The success of the entire process starts with the commitment of the top managers who play the critical role in the audit. Top managers need to be convinced that pre-assessment audit is necessary and successful certification and registration will benefit the organization by showing its commitment to quality for its customers. The management needs to be in the forefront for successful pre-assessment audit; nevertheless, this will only happen if the managers realize that good management systems will improve the efficiency of the business by minimizing duplication of the management systems that are wasteful. In the case of NBAD, the top management of the bank is committed to improve the quality of its services and systems to meet the needs of its customers. This commitment drove the managers in 2008 to carry a successful pre-assessment test required before ISO certification. Establishing a team for implementation Pre-assessment audit needs a committed team of staff for its successful implementation. After having a committed top management team, the plan must be made known to all the employees of the organization for them to own and support it. The quality assurance department ought to select a capable team that will spearhead the implementation process. As Asare, Davidson, and Gramling argue, an audit committee may be established to help in this process of auditing (181). The team may consist one of the member from the top management who will oversee and plan the implementation process together with the other people who are appointed from all the departments of the organization. These departments may include planning, marketing, quality control, and production among others. The representative of the management will motivate and direct all the other managers towards the implementation of the pre-assessment audit. In the NBAD, the quality assurance department, led by its manager, spearheaded the 2008 pre-assessment audit. Start awareness program The purpose of the awareness program is to inform all the stakeholders of the intended audit to incorporate them in the process. Awareness program may involve sensitizing the customers and employees on the benefits of the process. NBAD carried out several awareness programs to sensitize its employees and customers on the benefits they will gain from improved quality systems of the bank before its certification in 2008.
