Definition
DCA – Define, Communicate, Assure – is an organisational philosophy based on the principle that organisations should clearly define what matters, communicate it appropriately to those who need to understand it, and assure that activities of meaningful commercial, operational, compliance or safety value are being performed as intended.
Define
Organisations should define what is important, establishing clear expectations, responsibilities, standards and intended outcomes.
Definition should be proportionate to the significance of the subject and should consider from the outset how what is being defined can subsequently be communicated and assured.
A requirement that cannot be effectively communicated or meaningfully assured should be reconsidered, simplified or defined differently.
Communicate
Communication should be purposeful, proportionate to importance and appropriate to its intended audience.
The purpose of communication is not simply to distribute information, but to create understanding. Complex or technical information should therefore be communicated in a form appropriate to the knowledge, responsibilities and needs of the recipient.
Over-communication should also be avoided. Excessive information, notifications and instructions can reduce attention to matters of genuine importance. The significance of the message should therefore influence what is communicated, to whom, how and when.
These principles apply equally to communication with internal and external parties.
Technology, including artificial intelligence, may assist in creating, interpreting and delivering communication. It does not assume responsibility for that communication.
Responsibility cannot be delegated to AI.
Assure
Not everything needs to be checked.
Assurance should concentrate on activities and outcomes whose success or failure has meaningful value or consequence to the organisation.
The level and frequency of assurance should therefore be proportionate to the commercial, operational, compliance or safety value being protected and capable, where appropriate, of being quantified.
Assurance should provide evidence that what has been defined and communicated is actually occurring as intended.
Where the activity or outcome is insignificant, or the burden of assurance is disproportionate to its value or risk, assurance may create unnecessary work rather than organisational benefit.
Assure what matters. Not everything.
Responsibility and Inclusion
DCA is intended to encourage inclusion and responsibility throughout an organisation.
Clear definition enables people to understand what is expected. Appropriate communication enables them to understand why it matters and what they need to do. Proportionate assurance provides evidence that responsibilities are being fulfilled without creating unnecessary oversight or bureaucracy.
Responsibility ultimately remains with the people and organisations making decisions, irrespective of the technologies or systems used to support them.
The DCA Principle
DCA is founded upon a simple relationship:
Define what matters.
Communicate it appropriately.
Assure that it is happening.
Definition, communication and assurance should be proportionate to the value created or the risk protected.
DCA favours clarity over complexity, understanding over documentation, evidence over assumption, and meaningful assurance over unnecessary checking.
The DCA Philosophy was developed by David Bowman and first published in 2026. It reflects an approach to organisational governance based on proportionality, clarity, responsibility and evidence.
