Hays Recruitment

Migration, Solution Architecture & Design


Client Profile

Hays is a global leader in specialist recruitment with over £3bn in turnover. Over 8,000 staff in 380 offices across 27 countries, annually they place on average 80,000 people in permanent jobs, & 300,000 into temporary roles.

Hays had undertaken a massive technology innovation and renovation program and Proventeq worked with them as Solution Architecture & Design consultants; helping Hays to achieve technology innovations by providing specialist consultancy services.

The digital transformation program was split into two parts - migration and then a custom integration and build within Liferay. After migrating from Oracle WebCenter to Liferay and SharePoint and migration from OpenText to SharePoint, Proventeq’s team built a candidate search functionality in Liferay based on the geographical location of the user performing the search query. This was a challenge as no candidate information was stored within Liferay itself, and so our team integrated Hays’ background APIs to perform candidate searches for content stored on SharePoint Online and then display only the relevant candidates on the page.

Our migration experts utilized the Operational Management Information platform using Oracle BI as the front end and SSAS as the back end. They also ensured that all data adhered to the migration rules observed, which involved addressing any conflicting files to ensure a successful migration process for Hays Recruitment.

Enhanced content quality

All the items were successfully transformed with WCAG compliance standards while enhancing the quality of all content items and digital assets.

Reduced business downtime

The ‘phased migration’ and ‘delta management’ proved useful for the client's internal departments to transition into their new environment at their own pace.
