Waitrose & Partners – Mobile Development Platform

How we helped Waitrose & Partners put together their mobile development platform

In this case study, we explore how we helped Waitrose & Partners put together their mobile development platform.


Waitrose & Partners used multiple mobile devices running on many different operating systems in their stores. This meant they had lengthy application release cycles as each version of any software had to be developed and tested on different devices using multiple operating systems.

A development platform was needed that offered the best overall coverage of device and operating systems. The platform would also need to allow applications to be deployed more quickly, as well as implement fixes and enhancements in a timely manner. Finding and implementing such a platform would speed up time to market for any new mobile application introduced, giving Waitrose & Partners customers more choice and a better shopping experience.

As well as the mobile development platform, Waitrose & Partners were also looking for a technical partner who could offer:

  • Thought leadership
  • Technical expertise
  • Technical guidance


CACI reviewed several options and identified Xamarin as the development platform that should be selected. Once Xamarin was chosen, we built a proof of concept app enabling Waitrose & Partners to review and feedback into the development process.

Following the success of the proof of concept, we redeveloped and enhanced several existing applications using Xamarin for deployment across multiple stores. New applications were also developed and brought to market faster than before.


In selecting Xamarin through CACI, Waitrose & Partners were able to prioritise their focus on the introduction of new systems and applications. The deployment of existing applications was much quicker than before with the ability to implement fixes and enhancements in a timely manner.

The ability to quickly bring new applications to market has given Waitrose & Partner’s customers a better shopping experience and allowed applications to be developed for use on any customer mobile device.

Through our technical expertise & guidance, Waitrose & Partners achieved their end goal of having multi-device support. This in turn, allowed us to help Waitrose & Partners establish a mobile centre of excellence.

One of the key benefits to working with a trusted partner is that they recognised that one size doesn’t fit all. They provided a team and approach that was bespoke to the organisation which could be successfully delivered to provide a solution to meet Waitrose’s business and technical needs.
