Digital transformation call to action


What is digital transformation?

Digital transformation describes the process of undertaking significant technology change within an organisation to create an integrated and efficient ecosystem that enables a business to grow, innovate and increase efficiencies. Technology transformation often goes beyond the digital sphere and often reaches into cultural and operational change as well.


Why undertake digital transformation?

Businesses undertake digital transformation to achieve growth at a pace that would be impossible without it. For ambitious businesses looking for operational efficiency, de-risked and compliant architecture, and market leading customer experience, digital transformation presents an opportunity to innovate and gain traction in their market.


What is a digital transformation agency?

Digital transformation agencies are specialists in the delivery of large scale technical change. They combine deep technical knowledge with insights from successful transformation projects in similar businesses to strategically create a transformation roadmap for their clients. With multi-disciplinary teams, they have the expertise to advise on the full spectrum of technology transformation including digital product innovation, cybersecurity, technology selection and team enablement to de-risk and accelerate projects.


What services will a digital transformation agency provide?

Digital transformation agencies typically provide an end to end service on transformation projects, providing services including:

  • Discovery & Research
  • Technical Assessments
  • Digital Transformation Roadmap Planning
  • Solution Architecture
  • Proof of Concepts
  • Change Management
  • UX Design & Development
  • Cybersecurity
  • Data Analytics
  • Cloud Computing
  • AI and Machine Learning
  • DevOps
  • eCommerce
  • Internationalisation
  • API Integrations and Management
  • Digital Marketing Strategy


How long does digital transformation take?

Digital transformation projects vary in length depending on a number of factors. At Plug & Play, we deliver digital transformation projects for mid-market businesses and they typically take 1-2.5 years.  Larger transformations for enterprise businesses can take considerably longer and fall in the range of 4-6 years.

The delivery of digital transformation is typically phased, providing continual progress over time rather than a single launch date. In this way, risks can be better managed and the business can be engaged to a greater degree. A phased delivery also supports the change management process and team onboarding, while providing value and return to the business sooner.

Although a digital transformation project can be delivered in line with business objectives and a functional scope, a transformation is never truly completed. Technology doesn’t stand still and new technical opportunities emerge over time. The most forward-thinking companies will have stakeholders who are responsible for continual digital innovation and strategy.

What impacts digital transformation timelines?

  • Technical start point of the business
  • Goals and objectives
  • Functional scope
  • Stakeholder engagement, alignment and availability
  • Complexity of technology and change
  • Resource availability
  • Data integration and migration required
  • Configuration vs customisation of selected technology and platforms
  • Legal considerations
  • Onboarding, training and people management


How much does digital transformation cost?

Much like digital transformation timelines, the cost of transformation processes can also greatly vary. The enterprise digital transformation agencies are typically more costly than smaller digital transformation agencies like Plug & Play.

At Plug & Play, we support mid-market businesses with their digital transformation strategy and implementation. Our projects typically cost between £250k – £5mil. Larger transformation projects for enterprise businesses will cost much more than this depending on requirements.


Can digital transformation be delivered in-house?

It is possible for in-house teams to implement digital transformation, especially where the skills, resource and expertise is available. However, the best results are often achieved by combining internal teams with an external digital transformation consultancy.

A digital transformation agency brings the experience of a whole team that have worked on tens of digital transformation strategies and implementations. They have knowledge from recent projects and a team that is already set up to deliver the transformation strategy and IT roadmap. Although it is possible to hire people with this experience in-house, it is rare that it is achieved to the equivalent standard. The partnership between in-house stakeholders that have deep knowledge of the business and an agency that brings objectivity, insights, data and experience of managing large scale technical change creates a hybrid team with the experience and expertise to deliver a successful digital transformation.
