An office of highly motivated and professional government auditors responsive to the call for an honest, efficient and effective government and committed to the high standards of public service through a strong internal audit program in the bureaucracy.


To perform the role of professional internal auditor as a valuable support to the Local Chief Executive through effective monitoring and strengthening of internal control systems in order to achieve the highest quality standards of government service.


Department of Internal Audit, created under City Ordinance No. 18-187, is formerly known as Internal Audit Unit under the direct supervision of Mayor’s Office. It is a component of the internal control system and a strategic function in ensuring good governance throughout the bureaucracy.

According to the provisions of National Guidelines on Internal Control Systems (NGICS), the Internal Auditor in the Philippine Government has the fundamental role of assisting the Department Secretary or the Governing Body/ Audit Committee of the Governing Board in promoting effective, efficient, ethical and economical operations by appraising the adequacy of internal controls. The findings on the appraisal of internal controls are provided to said officials/ bodies to institute corrective and preventive measures and achieve the objectives of the department.

The role of the Internal Auditor is not about fault-finding. Neither is it investigative nor punitive. As one of the accountability mechanisms in public service organizations, the Internal Auditor reviews the extent of compliance with laws and policies under the authority of the Local Chief Executive.

As a component of the performance management framework of City Government of Muntinlupa, the Internal Auditor assesses the levels of performance against agreed measures, targets and objectives. The internal audit function is separate from, but complementary to, the day-to-day monitoring of internal controls and the conduct of continual management improvement, which are within the responsibility of operating units.


Department of Internal Audit (DIA)

The logo bears the new name of the office from Internal Audit Unit to Department of Internal Audit which symbolizes a big change from a unit to a full-pledged department which is still directly reporting to the Local Chief Executive.


The shape of the logo is generally a shield which symbolizes protection. The DIA safeguards the assets of the whole city. It protects the city not only from corruption but also from misallocation or underutilization of public funds, misuse of public property, unethical treatment of constituents/ clients especially those in frontlines, and to protect the public’s interest in general.


The symbol of owl in the logo was inspired by the ancient Greek goddess of wisdom, Athena. Owl, being her symbol, represents wisdom because of their large eyes and their success in hunting at night and catching creatures that were not able to detect by others.

Also, their ability to twist their heads around to such great degree could give the impression that they are “All seeing.”

Advisory, Integrity, and Governance

These three words symbolizes the additional services offered by DIA aside from the regular audit, its principles, and the result that DIA hopes to achieve.

Advisory is one of the services offered by DIA in which advices were given to the Local Chief Executive in the form of recommendations for his decision-making. It also represents the services being performed by the department as requested by other offices/ departments that are willing to be evaluated for process/ office improvement on top of the regular course of audit operations.

Integrity is the principle that every staff of DIA should live by. It means that every personnel of the office is expected to do what is right all the time since DIA happened to see wrongdoings from time to time during the course of audit.

Governance, or specifically good governance, is the result that DIA hopes to achieve by doing its mandated functions. DIA aims to recommend effective internal controls that every office/ department can implement so that good governance can be achieved in the City Government of Muntinlupa.

Color Blue

The color of the logo is mainly blue. It resembles the color of the ocean and like the ocean that appears to be limitless, DIA hopes to see every angle in each situation and understand it in a limitless perspective.
