Workstream Project Manager - Architecture & Technology

Job Title: Workstream Project Manager – Architecture \& Technology \& Solution

Division: Group

Remote

Purpose of Role

The Workstream Project Manager – Architecture \& Technology \& Solution is accountable for driving day\-to\-day delivery execution across the S4\+ Architecture, Technology and Solution workstreams, ensuring that architecture decisions, technical delivery, solution design, platform readiness and cross\-stream technology dependencies are planned, coordinated, tracked and delivered in line with the integrated programme plan.

This role supports delivery of the S4\+ target architecture and solution backbone across SAP S/4HANA core, surrounding SAP solutions, non\-SAP platforms, integration, environments, data, security, tooling, testing, cutover and transition to support. The S4\+ programme will implement a single SAP S/4 system across Minerals, ESCO and Corporate, with a target of 90% standardisation across core business processes and alignment to SAP fit\-to\-standard best practice.

The role works closely with the Chief Architect, S4\+ Tech Lead, Integration Lead, Tooling SME, Product Domain Architects, Deloitte, SAP, PMO, Data, Security, Testing and Change teams to ensure solution and technology delivery remains aligned, governed and on plan.

The role is critical to ensuring S4\+ delivers a harmonised, operable and future\-ready technology platform that supports Weir’s Product Operating Model and Global Product Domains. Global Product Domains provide ownership of global processes, the data that underpins those processes, and the platforms and systems that enable them

• Maintain detailed workstream plans covering architecture, technical delivery, solution design, integration, tooling, environments, security, testing, cutover and hypercare readiness.


• Track workstream milestones, deliverables, dependencies, risks, issues, assumptions and decisions.


• Ensure clear ownership of deliverables across Weir, Deloitte, SAP and third\-party delivery teams.


• Coordinate delivery activity across architecture forums, technical working groups, design authority meetings and programme governance.


• Identify delivery slippage early and work with accountable leads to define corrective action or recovery plans.


• Ensure Architecture, Technology and Solution workstream outputs are delivered within agreed scope, time, quality and budget parameters.

• Support the Chief Architect and S4\+ Tech Lead in coordinating architecture and solution governance across the programme.

• Support preparation of materials for the Design Authority, Technical Working Group and related architecture governance meetings.


• Ensure decisions are documented, owned, followed up and reflected in workstream plans.


• Help ensure solution decisions align with enterprise architecture, Clean Core principles, fit\-to\-standard guidance and future operating model requirements.


• Track exceptions, divergences from standard, open design points and unresolved cross\-domain decisions.


• Support escalation of material solution or architecture conflicts with clear options, impacts and recommendations.

• Coordinate planning and delivery activity across technology components including S/4HANA core, SAP RISE, cloud infrastructure, environments, landing zones, integration, security, data platforms and wider SAP/non\-SAP ecosystem dependencies.


• Work with the S4\+ Tech Lead to ensure technology delivery plans are aligned to SAP Activate phases and programme milestones.


• Track technology readiness for build, system integration testing, user acceptance testing, performance testing, cutover rehearsals, go\-live and hypercare.


• Ensure technical dependencies are visible and actively managed across data, integration, security, environments, testing and operational readiness.


• Support delivery governance between Weir, Deloitte, SAP, hyperscaler and other technology partners.


• Help ensure the S4\+ solution is designed and delivered for scalability, resilience, supportability and future AI / automation readiness. The Board Paper identifies scalable cloud infrastructure, AI readiness, harmonised data and real\-time analytics as key elements of the S4\+ scope and future value.

• Coordinate delivery activity across solution design workstreams, ensuring functional, technical, data and integration activities remain aligned.


• Support end\-to\-end solution planning across value streams and Product Domains.


• Track solution design dependencies across domains such as Finance, Sales, Supply Chain, Manufacturing, Service, Engineering, Data and Procurement.


• Ensure open design issues are captured, prioritised and escalated through the right decision forums.


• Support alignment between business process design, solution architecture, technical delivery and future\-state operating model.


• Help ensure design activity supports harmonised global value streams rather than re\-creating local or divisional fragmentation.


• Reinforce the programme’s move away from fragmented, local or point\-solution decision\-making towards a single integrated global operating model aligned to SAP S/4HANA and future digital capabilities.

• Own detailed planning and dependency management for Architecture, Technology and Solution workstream activities.


• Maintain workstream plans and ensure they are aligned with the overall integrated programme plan.


• Identify and manage dependencies across architecture, functional domains, integration, data, security, testing, tooling, change, infrastructure and supplier teams.


• Maintain accurate RAID logs and ensure risks and issues have clear owners, mitigations, due dates and escalation routes.


• Track cross\-workstream dependencies and ensure blockers are escalated early.


• Support PMO reporting with accurate, evidence\-based status updates.


• Ensure programme leadership has clear visibility of critical technology and solution risks that may impact timeline, cost, quality or readiness.

• Support SAP Activate\-aligned planning and governance across Architecture, Technology and Solution workstreams.


• Track readiness against key phase gates, entry criteria and exit criteria.


• Ensure required evidence is collected and maintained for architecture, solution design, technical build, test readiness, deployment and hypercare.


• Support gate reviews by coordinating inputs from architecture, technology, integration, data, security, testing and partner teams.


• Identify gaps in readiness evidence and drive follow\-up actions to closure.


• Help ensure workstream deliverables are audit\-ready and aligned to programme governance expectations.


• Support the programme methodology, which combines SAP Activate alignment with agile ways of working and earlier system testing during design and build.

• Work with the Tooling SME and PMO to ensure Architecture, Technology and Solution workstream delivery is tracked in the agreed programme tools.


• Maintain accurate workstream reporting across plans, milestones, RAID, dependencies, decisions, actions and readiness status.


• Support the use of tools such as LeanIX, Signavio, SAP Cloud ALM, Tricentis, Jira, SharePoint and other programme repositories where relevant.


• Ensure delivery evidence, architecture artefacts, decision records and technical status updates are maintained consistently.


• Support traceability between architecture decisions, solution designs, backlog items, test evidence and delivery milestones.
