Why does implementation often fail?

Under the guise of continuous improvement, most consultancies claim new technology and industry trends will help you.

But the problem with that is there’s no end goal. They keep billing while you don’t reach your destination.

You must set an end goal and create a process to get there. Otherwise, you can’t measure your progress, and your momentum grinds to a halt.

We implement The OpEx Eight, our proprietary 8-step process, to ensure you reach your destination.

Our Services & Solutions

Operations development with Duggan means we train, coach, implement, and manage projects with you.

Consultants rely on technology and trends to lead the way or share ideas for you to implement on your own. They have nothing to measure and no accountability.

Duggan sets a destination/goal, builds the project plan with you, and holds ourselves accountable for your project success.

  • "Tim spent three days with us to teach us Operational Excellence in the office methods, and help us apply them to one of our core value streams ... But by the third day, the team was fully sold on the ideas and extremely motivated to make the changes happen immediately. This is a credit to the OpEx methods and particularly to the way Tim taught with a no-nonsense approach, answered difficult questions, and guided the team to the future state value stream design and action plan."
