Messages that are designed to influence or change behaviour should be established on trust that exists between public partner decision-makers and their employees and / or consortia. Trust can be increased by establishing and maintaining credibility. Collectively, trust levels may be strengthened through the pursuit of common goals; shared understanding (see above); management follow-through on actions agreed with employees and / or consortia partners; mandating and enforcing project-wide adherence to governance, probity and compliance frameworks, etc. On an individual level, decision-makers can build trust with their employees, for example, by showing them respect, engaging them in decision-making processes, and where appropriate, delegating tasks and / or responsibilities.
