Who We Are

TAC is an innovative consultancy and solution company, specialized in the best practice framework like COBIT, ITIL, PMBOK, Prince2, Agile, CMMI, eTOM, Togaf, Stage&Gate, BPMN and related solutions. Originally founded in 1999 as a company with limited liability at Istanbul, Turkey.

Since our foundation, we work continually to improve our professionalism, capabilities, services, and products. We have successfully anchored “continual improvement” into TAC culture both on company and personal level as the guarantor and driving engine of our success.

Any consultancy service provider, big or small, generalist or specialist can only be as good as its consultants. As a matter of principle, TAC – contrary to most business and IT consultancy companies – is working solely with permanent employees. Our investment into further education and employee retention is highly above average. In the long run, this investment into our employees has always paid off by enabling us to retain and to constantly expand know-how within our company.


We bring together the best individuals for the job at TAC, organizing our teams to improve client connections. We combine practical project management skills with a dedication to customer care and quantitative analysis. We frequently cooperate across offices because we believe that outstanding ideas benefit our clients regardless of their origins. We encourage and honor team members at all levels who speak up and participate.

We believe that a particularly high degree of transparency, as well as clear communication throughout all project phases, are strengthening the bond of trust with our clients. An extraordinary high level of customer satisfaction is the prerequisite for a long-term customer relationship. Guided by this philosophy, TAC has been able to continually sustain double digit growth in the last decade.
