CASE STUDY PUBLISHED APRIL 2021

Siemens Gamesa

Sauce built MyTime — a bespoke HR portal and mobile app for Siemens Gamesa's Hull wind turbine factory, giving 750 employees, team leaders, and HR personnel real-time visibility of shifts, overtime, absence, and more.

PROJECT SUMMARY

Siemens Gamesa's Hull facility operates 24 hours a day, 7 days a week — and managing HR for 750 employees across complex rotating shifts was a growing challenge. Sauce built MyTime: a bespoke mobile app and web-based HR portal that gives each user type exactly the access they need. Employees check their own hours and shift patterns. Team leaders edit and update rotas in real time. HR has accurate, live workforce data across the site. The platform began with overtime management and has since expanded to cover absence monitoring, holiday requests, and a bonus scheme rewarding low sickness rates.

THE CLIENT

A Global Renewable Energy Leader with a Hull Heartbeat

Siemens Gamesa is one of the world's leading wind power companies — providing innovative renewable energy solutions across more than 90 countries and playing a central role in the global transition to clean energy. In Hull, the company operates one of its major UK manufacturing facilities: a wind turbine factory that never stops.

Running a 24/7 production environment at scale creates operational complexity that most businesses simply don't face. With 750 employees working across rotating shift patterns, managing HR efficiently — and accurately — is not just an administrative challenge. It's a business-critical one.

Global leader in wind power, operating in 90+ countries
Hull factory runs 24 hours a day, 7 days a week
750 employees across complex, rotating shift structures
Committed to local partnerships — sought a Hull-based digital team
Needed technology that could keep pace with operational demands

THE BUSINESS CHALLENGE

750 Employees, Rotating Shifts, and an HR Process That Couldn't Scale

Managing shift patterns for a 750-person workforce running around the clock is genuinely complex. Rotating schedules, overtime requests, absence reporting, and holiday entitlements don't pause — and without the right tools, HR teams spend significant time on manual processes that are slow, error-prone, and hard to audit.

Siemens Gamesa's biggest immediate pressure was overtime management. The existing approach required significant manual effort to track, verify, and communicate — creating friction for HR, inconsistency for team leaders, and a lack of visibility for employees who simply wanted to know what hours they'd worked.

What the business needed was a single, scalable platform that could:

Give HR accurate, real-time data on every employee's shift status and hours worked
Allow team leaders to update and edit shift patterns without HR bottlenecks
Enable employees to check their own hours and shifts via a simple mobile experience
Handle the complexity of rotating schedules across a 24/7 operation
Be flexible enough to expand as additional HR needs were identified
Be built by a local company that understood the region and could work closely with the internal team

THE SOLUTION

What MyTime Does for Siemens Gamesa

MyTime is a role-based HR management platform combining a web portal for HR and team leaders with a mobile app for employees — all built around the specific operational needs of a large-scale, 24/7 manufacturing environment.

Employee mobile app

Factory workers access their personal shift data, working hours, and attendance records directly from their mobile devices — giving every employee clear visibility of their hours across any given period, without needing to contact HR.

Team leader shift management

Team leaders log into the web portal to edit and update shift patterns in real time — making changes that are immediately reflected across the system for both HR and affected employees, without manual handoffs or paperwork.

HR management dashboard

HR personnel have a comprehensive view of the entire 750-person workforce — accurate, real-time data on shift patterns, overtime, and staffing status across the factory, replacing fragmented spreadsheets and manual records.

Overtime tracking & reporting

The feature that started it all. MyTime tracks overtime worked across the workforce automatically — giving HR an auditable record and giving employees confidence that their additional hours are accurately captured and visible.

Absence monitoring & bonus scheme

MyTime captures real-time absence data across the factory, enabling a performance bonus scheme: employees are rewarded when the site-wide monthly sickness rate falls below 5%. The data that drives the scheme comes directly from the platform.

Holiday request management

Holiday requests and entitlements are handled within MyTime — giving employees a single place to manage time off, and giving HR a consolidated view of planned absence across the workforce to support effective shift planning.

THE RESULTS

A Platform Integral to Factory Operations and Employee Experience

MyTime has moved well beyond its original brief. What began as an overtime management tool is now a core operational platform — one that HR, team leaders, and 750 employees rely on every single day. Siemens Gamesa describe it as integral to both operations and employee experience.

Real-time workforce visibility for HR

HR personnel can now access accurate, live data on shift patterns, overtime, absence, and holiday across 750 employees — replacing the manual processes and fragmented records that previously made workforce reporting slow and unreliable.

Faster, more confident shift management

Team leaders update and edit shift patterns directly in the platform — with changes reflected immediately across the system. What previously required manual coordination now takes seconds, with no risk of miscommunication.

Employee transparency and engagement

Every employee can check their own hours, shifts, and attendance record from their phone — removing the need to chase HR or rely on paper records. Clarity over working hours has meaningfully improved day-to-day employee experience on the factory floor.

A bonus scheme powered by live data

MyTime's absence tracking directly underpins a site-wide performance bonus — rewarding employees when the monthly sickness rate falls below 5%. The platform makes the scheme possible by providing the accurate, real-time absence data it depends on.

A scalable foundation for HR innovation

The modular architecture has allowed new HR functions to be added post-launch without disrupting the core system. Absence management and holiday requests have already been integrated — and the platform is ready for further expansion as needs evolve.

Integral to operations — not just a tool

In Siemens Gamesa's own words, MyTime has become integral to both operations and employee experience. It's not software that sits alongside the business — it's software that the 24/7 operation depends on, every shift, every day.

THE CLIENT'S VERDICT

"Sauce are a smart and forward-thinking company who have helped provide us with a great business tool that has become integral to operations and employee experience."
