  • Sustained

    Our approach in engaging with clients ensures knowledge transfer to key members of the client project team. This approach develops a level of self-sufficiency and sustainability with the client organisation.

    We set and agree tangible business targets at the outset of each engagement. We advocate the use of key metrics and scorecards in order to quantitatively assess progress against these targets through the duration of the project.

    Our approach is practical, and results oriented ensuring that the client organization can translate the project activities into its normal business practices.

    ‘Knowledge transfer leading to client self-sufficiency and sustainability……….’

  • Innovation

    We regularly work with leading edge technology and manufacturing organisations. Product innovation is the essence of what they do. Our core methodologies provide robust frameworks. However, we develop solutions and provide support that is bespoke and innovative. Each engagement is designed to specifically address the needs of the client.

    Our consultants utilize the appropriate tools and techniques in an innovative manner in order to best satisfy the needs of the project.

    ‘Designed solutions are bespoke and innovative….’

    Our consultants are experienced professionals with extensive experience in both line management and consulting. This mixture of experience enables empathy with client staff at all levels in the organizational hierarchy.
