Case Studies & Projects Portfolio
Complex systems. Clear requirements.
Solutions ready for delivery.
More than 20 years of working at the intersection of business and technology have taught me that technology itself is rarely the biggest challenge in complex projects.
The real challenge is translating the needs of multiple stakeholders, existing systems, regulatory constraints and integration dependencies into a solution that can be clearly designed, implemented and tested.
The following case studies present selected projects across enterprise integrations, CRM, pharmaceuticals, banking, access management and regulated systems. My experience covers requirements engineering, UML/BPMN modelling, reverse engineering, impact assessment and collaboration with distributed EMEA/APAC teams.
Global Integration Programme for the Pharmaceutical Industry
How do you maintain architectural and requirements consistency when a global programme spans multiple systems, countries, deployment waves and teams?
1. Context
A global pharmaceutical organisation was running a long-term programme involving numerous integrations, multiple deployment waves and several parallel sub-projects.
The scope included integrations related to a global GTM platform and systems such as OCE, SailPoint, Reltio and PCS.
The programme involved stakeholders and teams operating across several time zones, including EMEA and APAC.
2. Challenge
In an environment involving multiple systems and teams, a local change rarely remains local.
A new requirement could affect the data model, existing integrations, user lifecycle processes, downstream systems and the scope of future deployment waves.
The challenge was therefore not simply to document individual functionalities, but to maintain a consistent view of the entire integration landscape and identify the impact of proposed changes before implementation.
3. Waldemar’s Role
Waldemar worked as a Core Senior Business–System Analyst, with responsibilities covering the analytical side of the integration programme, the canonical integration model and the Change Request process.
His role connected business, system and integration perspectives while coordinating with business stakeholders, technical teams and solution owners.
4. Scope of Analysis
The work included:
- business and system requirements analysis,
- system integration analysis,
- maintenance and evolution of the canonical integration model,
- Change Request analysis and impact assessment,
- dependency analysis across systems,
- analytical support for deployment waves and sub-projects,
- user lifecycle analysis,
- support for solution design prior to implementation and testing.
Selected assignments included OCE–SailPoint integration and Reltio–PCS integrations implemented across multiple countries.
5. Methods & Deliverables
Depending on the project stage, deliverables included:
- integration models,
- High-Level Design documentation,
- Business Requirements Documents,
- SLAs,
- RFP materials,
- test plans,
- Change Request analysis,
- impact assessments,
- requirements and project documentation,
- backlog and requirements management in JIRA.
Discovery sessions, workshops, demonstrations and retrospectives were also an important part of the work.
6. Stakeholder Collaboration
The programme required close cooperation with distributed teams and stakeholders from multiple regions.
The analyst’s role went beyond collecting information. It involved bringing different perspectives together into a clear and consistent solution model, while ensuring that decisions made within one area reflected their impact on the wider ecosystem.
7. Outcome
The work resulted in a consistent set of models, analyses and documentation supporting subsequent programme changes and deployment waves.
The canonical integration model provided a shared reference point for dependency analysis, while impact assessments supported informed decision-making before changes were implemented.
Business value: improved predictability of changes in a complex integration environment and clearer communication between business and technical teams.

Project Portfolio
Selected Projects Across Enterprise IT, Integrations, CRM and Regulated Environments
Over more than 20 years in IT, I have worked on projects ranging from global integration programmes and enterprise CRM platforms to access governance, regulatory transformation and mission-critical public-sector systems.
My role has typically been positioned between business and technology: clarifying requirements, modelling processes and solutions, analysing integrations, reconstructing legacy behaviour and preparing delivery teams to implement changes with a shared understanding of the target solution.
The portfolio below presents selected assignments across pharmaceuticals, banking, finance, telecommunications, energy and the public sector.
CRM & Customer Lifetime Value in Banking
How do you develop a complex CRM environment, when part of the knowledge about the existing solution first needs to be reconstructed?
1. Context
The project involved a Customer Lifetime Value / CRM environment for a European bank and covered both ongoing development and maintenance of an existing solution.
Waldemar was responsible for maintaining the solution model in Enterprise Architect, analysing sprint scope, facilitating workshops and reverse-engineering existing CRM functionalities and integrations.
2. Challenge
Systems developed over many years do not always have documentation that accurately reflects their current behaviour.
Before designing a new change, it was therefore necessary to establish:
- how an existing functionality actually worked,
- which components it depended on,
- where system responsibility boundaries were located,
- how a proposed change would affect the existing landscape,
- how to describe the change clearly for both business and development teams.
3. Waldemar’s Role
As a Senior Business–System Analyst, Waldemar was responsible for end-to-end analysis of sprint scope and for maintaining consistency between business requirements, the existing solution model and planned changes.
4. Scope of Analysis
The work included:
- analysis of upcoming sprint scope,
- reverse engineering of existing CRM functionalities,
- integration analysis,
- maintenance of the Enterprise Architect model,
- dependency identification,
- clarification of business requirements,
- preparation of changes for development teams.
5. Methods & Deliverables
The work involved:
- Enterprise Architect models,
- use cases,
- user stories,
- change documentation,
- business and technical workshops,
- as-is analysis,
- reverse engineering,
- end-to-end analysis.
The CV specifically confirms responsibility for maintaining the EA model as well as delivering use cases, user stories and supporting documentation for changes.
6. Stakeholder Collaboration
Workshops were conducted with both business stakeholders and development teams.
This made it possible to compare business expectations with the actual behaviour of the existing solution and identify gaps between the expected and technically feasible scope of a change.
7. Outcome
Each change was supported by clear analytical documentation connecting the existing system, the business requirement and the work of the development team.
Reverse engineering allowed new changes to be designed based on the actual behaviour of the solution rather than outdated assumptions or incomplete documentation.

User Access Management for Finance & Budgeting
How do you translate access policies and governance principles into processes that make sense to users, business stakeholders and IT teams?
1. Context
The project involved User Access Management for finance and budgeting systems within an international organisation.
The scope covered access processes, roles, permission models and governance principles.
Waldemar led the analysis, prepared business and technical documentation, facilitated workshops and supported end-user training.
2. Challenge
Access management sits at the intersection of several areas:
user needs, organisational structure, security requirements, operational processes and system constraints.
Defining who should have access is not enough.
A complete solution must also establish roles, approval paths, access provisioning and removal processes, responsibilities, exceptions and governance across the entire access lifecycle.
3. Waldemar’s Role
Waldemar worked as the Senior Business–System Analyst responsible for UAM analysis, connecting process requirements with role and access models.
4. Scope of Analysis
The scope included:
- access provisioning and modification processes,
- business and system roles,
- permission models,
- approval flows,
- governance,
- ownership and responsibilities,
- exception scenarios,
- the end-user perspective of new access management processes.
5. Methods & Deliverables
Deliverables included:
- process models,
- role and access models,
- business documentation,
- technical documentation,

GDPR & Blockchain Platform for the Financial Sector
How do you connect regulatory requirements, distributed architecture and integrations with multiple financial institutions?
1. Context
The engagement covered two significant areas within the financial sector: implementation of GDPR-related regulatory changes and development of a DLT/blockchain platform designed to work with multiple banks.
The solution supported public and private document storage and had to address requirements associated with the “right to be forgotten”.
2. Challenge
The project combined three complex areas:
regulation + inter-organisational integrations + emerging technology.
In a solution involving multiple financial institutions, a legal requirement has to be translated into precise system behaviour, data considerations, integration requirements and test scenarios.
3. Waldemar’s Role

Mission-Critical System in a Regulated Environment
How do you conduct systems analysis when security and unambiguous documentation are integral parts of the solution itself?
1. Context
The project involved a web application designed for border guard services.
It was developed in a regulated, security-focused environment and delivered iteratively using Agile practices.
2. Challenge
In mission-critical systems, an ambiguous requirement is not merely a project management issue.
It may affect system security, user behaviour, testing and the decisions made by implementation teams.
Maintaining consistency between business documentation, the system model and the scope of subsequent sprints was therefore particularly important.
3. Waldemar’s Role
Waldemar was responsible for preparing business and technical documentation, maintaining the solution model in Enterprise Architect and providing analysis for subsequent Agile sprint scopes.
4. Scope of Analysis
The work included:
- business requirements,
- system requirements,
