Project: Migration of legacy Business Objects (BO) reports to modern Tableau dashboards as part of enterprise modernization from legacy reporting systems to future state analytics.

• We are looking for a highly skilled Senior Associate with strong experience in Business Objects (BO) reporting, Tableau development, and enterprise-scale migration projects. This role will support the end-to-end migration of reporting assets from a legacy BO environment into a modern Tableau based analytics platform.
• The ideal candidate is hands-on with strong analytical skills, deep understanding of reporting ecosystems, and experience translating legacy semantic layers and universes into scalable, efficient Tableau dashboards.
• For the senior BO would say the current description for 7+ years’ experience is the minimum we should consider for the lead position. This effort will require coordination with several teams so want to stress the point called out around prior experience leading similar efforts in end-to-end migration.
• This effort would involve migrating/modernizing both BO and Tableau reports, not necessarily one to the other. There is a large BO footprint that will remain in BO with focus on updating those universes and migrating/certifying the associated reports. We are looking for someone with robust understanding of BO Universes and semantic modeling to lead here.
• Separately, there is another reporting footprint in Tableau, including supporting Alteryx workflows, that we are also migrating. Experience with both tools will be required which is called out well; any experience with Alteryx or similar GUI tools will be a plus.
• To clarify this is the next stage of the EAP modernization the teams have been engaged on, as we are modernizing our underlying data landscape, the business is not anticipating much change to the report layer, however.
• We should also add a section that includes data certification of reports, experience working with stakeholders and building confidence that their reports tie out will be critical.

• Analyze existing BO reports, universes, SQL, and semantic layers.
• Reverse engineer and document business logic, KPIs, data rules used in legacy BO reports.
• Re design and develop equivalent or improved Tableau dashboards aligning with future state architecture.
• Validate data output between legacy and Tableau reports to ensure functional parity.

• Develop dashboards using Tableau Desktop & Tableau Server/Cloud.
• Optimize dashboards for performance, scalability, and user experience.
• Build reusable data sources, extract strategies, filters, parameters, and advanced calculations.
• Implement row level security, governance standards, and publishing workflows.

• Work with ETL/Data Engineering teams to validate underlying data pipelines and required transformations.
• Identify gaps in source data, logic, and mappings during migration.
• Collaborate on designing new data models aligned to future-state architecture.

• Assess migration complexity across BO inventory and classify reports for rewrite/enhancement.
• Build migration templates, design patterns, and standardization frameworks.
• Assist in phasing, prioritization, and cutover planning.
• Support UAT cycles and defect resolution.

• Work closely with business SMEs, data owners, ETL teams, QA and product managers.
• Conduct requirement workshops and sign off sessions for migrated dashboards.

• 7+ years of experience in BI/reporting tools
• Strong hands-on expertise in Business Objects (WebI, Designer, BO Universes, BO Reports)
• 5+ years in Tableau Desktop & Tableau Server/Cloud
• Strong SQL skills on Oracle / SQL Server / Snowflake
• Experience rewriting BO logic → Tableau (calculated fields, LODs, parameters, filters, aggregations)
• Good understanding of ETL workflows, data models, data quality validation
• Ability to optimize Tableau dashboards for performance

• Must have worked on at least one end to end migration from:
• BO → Tableau, or any legacy BI → modern BI migration
• Experience mapping BO universes to Tableau data models
• Experience reconciling legacy KPIs with new data models
