Enterprise project undertaken during my employment. The platform is owned and operated by the respective organisation; my contribution is described below.
This is a case study of an enterprise HR and employee self-service portal delivered through Gönenç Türkekul's former employment. An external supplier built the portal software; the in-house team prepared the environment, integrated it with corporate systems and organised user acceptance testing. The page explains how those responsibilities were split, how vendor dependencies and readiness were managed and his specific role in coordination and project governance. It describes delivery work, not a product he owns, sells or licenses.
Supplier product, in-house fit
Large organisations handle a constant flow of employee requests and HR records. In this initiative, the HR portal application came from an external supplier. Our in-house team's job was to make it work inside the organisation: preparing the environment, connecting it to corporate systems, organising acceptance testing and running the project with the supplier and HR stakeholders.
How HR tasks worked before
HR and employee-related processes needed digitalisation, better integration and stronger self-service. Many interactions between employees and HR depended on manual steps, and HR data did not flow easily between systems. Employees had limited ways to handle routine requests themselves, so simple tasks often meant contacting HR directly.
The problem to solve
The organisation wanted employee-facing HR interactions to move into a self-service portal connected to its corporate systems. Buying a supplier product solves part of that; the rest is making it fit an existing organisation, with its own systems, data and processes. Much of that fit was the in-house team's responsibility, and it is the focus of this case.
Who delivered what
Two kinds of work came together. The supplier provided the portal functionality: employee self-service and structured HR and employee data workflows. The in-house team provided what the portal needed to run in the organisation: the application environment, integrations with corporate systems, user acceptance testing and project coordination. This page describes delivery and readiness work; it does not describe adoption figures or claim a completed organisation-wide rollout.
Capabilities in scope
- Employee self-service (supplier-built portal)
- HR and employee data workflows (supplier-built portal)
- Application environment (in-house team)
- Integration with corporate systems (in-house team)
- User acceptance testing (in-house team with business users)
Supplier, team and my role
The portal software was built by the supplier, not by us. Our in-house team prepared the environment, worked on the integrations with corporate systems and organised user acceptance testing with business users. My responsibility was the project and dependency side: coordinating the supplier, aligning HR and technical stakeholders and steering release-readiness decisions.
My part
- Vendor and dependency coordination
- Project governance and planning
- UAT coordination and release readiness
- Stakeholder communication across HR and technical teams
The team’s part
- Application environment setup (in-house team)
- Corporate system integrations (in-house team)
- Integration and acceptance testing (in-house team with business users)
- Portal functionality and self-service features (supplier)
Trade-offs and constraints
Working with a supplier product shifts the trade-offs. Customising the product too much creates long-term cost; customising too little leaves gaps in how the organisation works. Every integration also depends on the supplier's timeline and the readiness of internal systems, so the plan had to treat those dependencies, and acceptance testing, as delivery decisions rather than final checks.
Readiness and intended value
- Intended value
- digital HR and employee workflows, easier self-service access for employees, more structured HR service delivery and HR systems connected to other corporate platforms. This page describes delivery and readiness work; adoption is not measured or claimed here.
What I learned
Buying software does not remove delivery work; it changes it. Integration, environments and acceptance testing decide whether a supplier product becomes something an organisation can use. I learned to make the split of responsibilities with a supplier explicit from the first day, and to treat user acceptance testing as a product decision with clear exit criteria.



The case in four stages
- BeforeEmployee-facing HR tasks relied on manual steps, with limited self-service and integration.
- DecisionAdopt a supplier portal and focus the in-house team on environment, integrations and UAT.
- SystemA supplier-built self-service portal, connected to corporate systems by the in-house team.
- ChangeHR interactions are designed to move into self-service, with readiness tracked through acceptance testing.

Technical, operational and managerial
Technical
The technical work was about fit, not about writing the portal. The in-house team set up the application environment, connected the portal to corporate systems and tested those integrations. The portal's internal functionality was the supplier's responsibility.
Operational
For employees, the point is handling routine HR tasks themselves; for HR, it is structured data workflows. Making that real meant coordinating the supplier, running acceptance testing with business users and preparing people for a new way of working.
Managerial
This is where my role sat: keeping the supplier, HR stakeholders and internal technical teams on one plan, tracking dependencies between them and steering readiness decisions. Clear agreement about who owned what was the main tool for keeping the project predictable.
Questions answered
What role do vendor dependencies play in HR portal delivery?
A large one. The supplier's release timeline, the readiness of internal systems and the availability of business users for testing all affect when a portal can go live. Treating these as tracked dependencies, rather than assumptions, is a core part of the delivery work.
How were integration and acceptance responsibilities split?
The supplier provided the portal functionality. The in-house team set up the environment, worked on integrations with corporate systems and organised user acceptance testing. Gönenç Türkekul coordinated the supplier and stakeholders and steered readiness decisions.
Did the in-house team build the HR portal?
No. The portal software was built by an external supplier. The in-house team's contribution was the environment, integrations, acceptance testing and project delivery that let the portal run inside the organisation.
Is the portal live and widely used?
This page describes delivery and readiness work. Go-live and adoption details have not been confirmed for publication, so no usage figures or completed rollout are claimed.
