The term ‘lens’ has been specifically chosen for this guide to reflect the ana logy between human vision and the interaction of people. This context also facilitates the analogy between the tools and techniques used to enhance, correct, protect and improve this interaction.

The eye is the vehicle through which the brain understands distance, shape, form, colour, shade, light, dark, and dimensions. These are based upon frames of reference shaped by, for example:

• culture and beliefs
• values and ethics
• experience and upbringing
• preferences and prejudices
• education and influences
• context and external factors
• perceived opportunity and risk
• mood and behaviours

Throughout our lifetime, our vision evolves, becoming stronger or weaker. Sometimes intervention is required in the form of glasses, contact lenses or surgery. Equally, our own frames of reference evolve over time, adapting and reshaping through exposure to variety.

The human dimension gives each of us the capacity to choose to evolve according to our circumstances. We have the ability to employ tools to refine our perspectives. We can identify which corrective action may prove useful and implement effective tools. When seeking to improve or correct vision, we determine the type and intensity of lens required in conjunction with the existing range of products, such as glasses, telescope, microscope, periscope, magnifying glass, endoscope, night-sight or sunglasses.

In project, programme and portfolio management, there are infinite and complex human dimensions. This guide offers lenses to enhance, correct, protect and improve relationships, behaviours and outcomes within these environments.
