Design & Delivery Assurance

What is Design and Delivery Assurance?

IT change is complex and expensive.

Get it right and you’re the hero of your board and shareholders.

Get it wrong and it could be career threatening.

We understand that embarking on major change projects presents a range of challenges that you may not be familiar with.

But we are. It's what we do. Day in, day out.

Our Design and Delivery Assurance is a collection of services designed to ensure you achieve success through complex IT change.

We help you provide confidence to your stakeholders that projects, programmes and portfolios will achieve their scope, time, costs and quality objectives as well as delivering their desired business goals.

We provide two fundamental handrails that guarantee the effective realisation of your change efforts.


we act as independent and expert custodians of your reference architecture.


we provide a solid governance framework for your programme or project, with expert support for the duration of the initiative.

In short, we are there to support you as part of a winning formation to enable you to achieve your business objectives.

Why do you need Design and Delivery Assurance?

Business doesn’t sit still. Change presents both opportunities and risks.

Whatever your industry or job title, if you are responsible for transformation within your organization there are challenges hidden in large change initiatives which we can help you overcome.

Perhaps you'll recognise some of these:

Lack of confidence in the experience of a project/programme manager, or a history of failed initiatives

A program heading off the rails with missed milestones, spiraling costs and lack of direction

Short (or no) corporate memory for projects resulting in constant ‘wheel reinvention’ and wasted resources

Inappropriate or inconsistent application of delivery methodology compromising quality or putting milestones at risk

Conflicting technology choices in day to day activities or projects, causing unexpected costs, delays and eroding organizational goodwill

Multiple competing and politically charged stakeholders

Multiple delivery teams with multiple suppliers increase planning and communication complexities

The transformation of legacy systems is proving technically very challenging and impacting business as usual

Vendors designing in expensive, unnecessary and long term supplier dependencies

Scope creep, conflicting requirements and unclear objectives result in bottom line impacts

Any of these challenges can be potentially life threatening for your change initiative.

Indeed, in our experience many projects have failed because one or more of these issues were not recognized and addressed appropriately.

The result? Consequences range from career repercussions for the professional responsible for the project or programme, to serious reputational damage for the organization in question leading to profit erosion, loss of market share or decline in value.

How are Design and Delivery Assurance Services delivered?

Our Design and Delivery Assurance services can accompany you for the duration of your change initiatives, or for just part of the journey (for instance, in the case of an Audit & Rescue intervention).

The frequency/intensity of our presence throughout the transformation will depend on your needs and will be defined early on in an initial proposal.

Initially we will engage with senior stakeholders responsible for the transformation to set out clearly the terms of our engagement. This is generally achieved through interviews and workshops to ensure we have clearly identified the key areas you will need support with.

We will then work across the different layers of the project, engaging with relevant stakeholders as appropriate. Depending on the service agreed, Mosaic Island staff will either be fully embedded in the transformation or simply present in an advisory capacity at regular intervals throughout the initiative.

Assurance services scale according to the size of your initiative. We can either be deeply embedded in your team or act in a more hands-off capacity. Either way we will ensure that we will provide the appropriate level of assurance to guarantee the success of your complex change.
