Insights Series – Issue 4: Achieve twice as much but only work half as hardA paper on increasing workforce productivity with Zwanger-Pesiri


Zwanger-Pesiri's business model rests on providing radiology services that meet the highest professional standards while also offering superb, personalized customer service.

This paper, co-authored by Robert Day, Chief Operating Officer of Zwanger-Pesiri Radiology, offers a detailed analysis of how the radiology practice succeeded in this effort, with personal insights from senior management and practical examples of best practices and impactful innovations.

  • The key to personalized service is employees who know what the company is trying to achieve and understand how their own efforts contribute to success.
  • Workforce productivity is raised to peak levels not simply by demanding that people work longer or harder, but by inspiring them to work with more passion, harnessing their creativity, and giving them a sense of ownership.
  • If employees believe they are part of a superior team and raise their own performance to that level, the benefits for patients - and for the organization - follow.
