AI Initiatives: identifying and promoting practical Artificial Intelligence use cases across the IT department
As Interim Head of IT for a German medium-sized industrial distributor, I am responsible for 31 IT employees and lead the digital and organizational transformation, reporting directly to executive leadership. I took over an IT department with almost no basic structures – no clear roles, processes, documentation or ticket system – and with significant technical debt that tied up most of its capacity. Introduced agile principles and ways of working in the IT organization and transformed the traditionally structured IT department into cross-functional Scrum and Kanban teams focused on transparency, collaboration, and customer value delivery.
Redesigned the entire IT organization by establishing a modern operating model, introducing new roles such as Product Owner, Scrum Master and Solution Architect and strengthening the organization through strategic hiring and targeted capability development. Recruited and onboarded Agile Coaches to accelerate the transformation and personally managed and coached Scrum Masters as well as IT department leaders to foster servant leadership, self-management and a culture of continuous improvement.
Aligned IT-internal planning across eight teams to three Flight Levels based on Klaus Leopold (strategy, coordination, team), laying the foundation for later company-wide portfolio management. Consolidated the backlog of more than 10 workstreams and prioritized it by business value and cost of delay. Introduced a ticketing system to increase transparency and enable data-driven decision-making, flow-based work management, and greater accountability at all levels.
Established and supported multiple cross-functional teams, including the Operational Core (ERP) domain with dedicated streams for Support, Feature Development and ERP Migration, as well as teams responsible for Warehouse Operations, Maintenance & Operations (M&O) including system engineering and security, Modern Workplace, Data Quality and integration initiatives. Worked closely with Agile Coaches to support team development, remove impediments, and continuously improve delivery effectiveness.
Acted as Interim Product Owner for the operation and enhancement of the existing ERP landscape while supporting the ERP migration as a Project Manager. Reorganized the project organization and had the already negotiated contract with the implementation partner realigned with a focus on approach and overall responsibility; Phase 1 (financial accounting) has been live since October 2025. Collaborated with the selected implementation partner to design and establish the project organization and target operating model for the ERP transformation, introducing agile delivery structures and ways of working. Facilitated the alignment between business, IT and the external vendor and played a key role in negotiating the contractual framework and delivery model to ensure a sustainable foundation for the transformation program.
Initiated the strategic modernization of the workplace environment through the adoption of Microsoft 365 cloud capabilities, establishing the foundation for enhanced collaboration, scalability and future digital services.
Launched AI initiatives to identify practical business use cases and promote the responsible adoption of Artificial Intelligence across the IT department. Encouraged self-management and empowered teams to take ownership of decisions, delivery and continuous improvement.

About the technology
What MantisBT does
MantisBT, also known as Mantis Bug Tracker or simply Mantis, is an open-source web application for reporting, organizing and resolving software defects. Teams use it to manage issues, assign responsibility, track status and preserve a clear history from discovery to closure. Its PHP and database foundation supports controlled deployment on company infrastructure.
Core workflows
MantisBT adapts to structured support and quality processes through projects, categories, priorities, severities, custom fields and configurable statuses. Specialists shape workflows around release planning, customer support, internal service requests or regulated change control. Notifications and access rules help keep ownership visible without relying on email threads.
- Configure projects, users, roles and permissions
- Create issue states, fields, filters and reporting views
- Set up email notifications and escalation rules
- Prepare exports and dashboards for review meetings
Ecosystem and extensions
Strong MantisBT professionals work across PHP, relational databases, web servers and authentication systems. They may connect MantisBT with Git repositories, continuous integration tools, directory services or service desks through plugins, APIs and automation scripts. They also understand upgrades, configuration management, backups and secure server operation.
When expertise helps
Companies often bring in freelance specialists when an existing tracker has become inconsistent, a migration needs careful planning or teams need one workflow across several projects. Germany-based organizations may value German-language coordination, while distributed teams can collaborate effectively through documented requirements, remote administration and scheduled reviews.
- Consolidate separate issue trackers or outdated workflows
- Migrate projects, users, attachments and historical issues
- Integrate repositories, identity providers or reporting tools
- Improve permissions, notifications and release reporting
Choosing a specialist
Look for professionals who can explain trade-offs instead of only installing the application. Relevant evidence includes a clean project and permission model, tested migration procedures, maintainable plugin or API work and clear documentation for administrators and users. They should also be comfortable diagnosing database, mail delivery and web-server problems.
Project outcomes
A well-executed MantisBT engagement leaves more than a configured tracker. It delivers consistent issue data, predictable routing, useful reports and a supportable upgrade path. Before work begins, agree on workflow rules, integrations, data ownership, acceptance checks and knowledge transfer so the result remains useful after the specialist leaves.
Frequently asked questions
Quick answers to the questions that come up most around MantisBT.
MantisBT is used to report, prioritize and track software defects, support requests and other work items. Teams can manage projects, assign issues, control permissions, send notifications and review progress through filters and reports.
Mantis Bug Tracker is often chosen for focused issue tracking with an open-source codebase and a comparatively direct workflow. Jira and Redmine may offer broader planning or collaboration features, so the right choice depends on integration needs, process complexity and the level of customization required.
A strong MantisBT specialist usually understands PHP, SQL databases, Linux or other server environments, web-server configuration and email delivery. Experience with Git, REST integrations, LDAP or other identity systems is valuable when the tracker must fit into an existing toolchain.
MantisBT can be straightforward to configure, but complex migrations and integrations require deeper practical experience. Match the specialist to the scope: basic workflow changes need different expertise from database migrations, custom plugins or security-sensitive administration.
Yes, MantisBT work is well suited to remote collaboration because configuration, testing and documentation can be handled through secure access and shared repositories. For teams in Germany, clarify language expectations, access procedures, maintenance windows and any need for occasional on-site workshops.
Before modifying Mantis, a specialist should review the application version, PHP and database compatibility, plugins, custom fields, permissions, mail settings and backup process. They should test changes in a separate environment and define a rollback plan before applying them to production.
Ask for a clear workflow design, documented configuration and evidence that migrations or integrations were tested. Quality MantisBT work is predictable, maintainable and understandable to the team that will operate it after handover.
Typical deliverables include a configured project structure, permission matrix, workflow documentation, integration setup, migration validation and administrator guidance. For MantisBT, also request backup and upgrade notes so future maintenance does not depend on undocumented settings.
