ASSIST Business Development with the following:

• Development of the IP Architecture and Solution Description to be used for offer submission (and integration/dependencies with the E2E solution).
• Pre-determine a Physical and Logical Solution Architecture; partition and allocate system requirements and functionality to the architecture; analyze and evaluate alternative solutions; define subsystems and system elements and requirements.
• Identification of Key Technical Risks and Issues, develop mitigation plans
• Identification of roadmap gates ensuring time to market (for Nokia IP products and dependencies with non-Nokia products).
• Provide key inputs for technical decisions relating to system requirements and system architecture/design.

Project Execution Phase:

• System/Solution Requirements Development.
• Identification of key Use Cases; agreement on key acceptance criteria.
• Derive products and solution requirements in line with the SOW and solution description while being fully coordinated with project management, design and deployment team; perform requirements designation and importance analysis; perform verifiability analysis; perform risk analysis.
• Development of E2E Solution Architecture inclusive of Residential Broadband solution integration with Mobile Core and support to High-Level Design (multiple technology domains).
• Determine a Physical and Logical Solution Architecture; partition and allocate system requirements and functionality to the architecture; analyze and evaluate alternation solutions; define subsystems and system elements and requirements.
• Perform Use Case Analysis, scenario determination and develop sequence diagrams to support the requirements analysis, architecture & high-level design activities.
• Review HLD/LLD/Interface Specification
• Proactively seek to identify and address technical risks. In co-operation with the PM/TPM conduct risk assessments on the project and all suppliers; identifying and executing mitigation strategies to limit impact; support on reporting of risk exposure (cost, schedule, other); escalating, as appropriate.
• Review roadmap alignment with solution to be implemented with PLM engagement.
• Technical aspects of Gate & Milestone Execution.
• Provide key inputs and be accountable for technical decisions relating to system requirements and system architecture/design.
• Requirements & Design traceability.
• Maintain traceability between requirement sets (Customer, System, Subsystems and System Elements), maintain traceability to architecture and design documents; support traceability to verification activities.
• Technical change impact assessment end to end (both internal & 3^rdparty).
• The Solution Architect is accountable for the technical accuracy of the design solution (i.e.: as defined in the SA&HLD etc.) – and the resulting implementation.
• The Solution Architect assists with technical delivery of the end-to-end project – design implementation to acceptance.
• Technical support, manage, review 3rd party suppliers and vendors - including:
  • Ensuring that all parties involved in the solution development (SI project team, the customer, 3rd party suppliers, subsystem design teams) clearly understood their technical scope/objectives (through document reviews, workshops, presentations, informal Q&A)
  • Reviewing and assessing the technical progress of all suppliers – including 3rd Parties.

Key Deliverables:

• Solution Architecture and Description, Technical Scope of Work.
