Moving you from a single-source contract to a multivendor service, owned by you

Methods has extensive practical experience in supporting public sector customers to leave single-source, legacy contracts and move to multivendor services, shaped by our experts.

We use our knowledge and experience to ensure your existing services remain uninterrupted while we work with you to shape a range of areas. These include contractual and commercial requirements, technology, planning, operating models, organisational design, business change, and exit and transition management.

Exiting legacy contracts and transitioning into a multi-supplier operating model is complex. Although many public sector organisations have started many have still to tackle hard questions on the ‘what?’ and the ‘how?

How can we help?

Methods offers industry-leading planning and expert advice for contract exit and transition, underpinned by industry best practice. Our experts know how to bring together all aspects of major change programmes (style, business and technology), while aligning with ‘HM Government Shared Learning, Exiting Major IT Contracts: Guidance for Departments’. 

We use a structured framework of services, built on our experience and designed to guide our public sector customers through the end-to-end process effortlessly, including managing risks, and ensuring compliance with policies and standards. 

To support our customers and offer the maximum possible value, we offer the framework in its entirety, or on a stage-by-stage, component-by-component basis. 

Finally, we believe it’s important to match the skills, styles and approaches of our teams and people with the customers they’re supporting. This encourages collaboration and ensures knowledge transfer throughout every project. 

We achieve this through a 4-step process:
