Scalable Systems Engineering

Almost all industries depend on large-scale, complex computer-based systems to power domains ranging from energy grids and manufacturing processes to scientific research and transportation and communications networks. The Scalable Systems Engineering Group (SSE) at the Pacific Northwest National Laboratory (PNNL) has a proven track record in the successful delivery of customized solutions involving complex information systems architectures that enable innovation in business processes, analysis systems and scientific research.

Researchers in the SSE group have the knowledge and experience to design, develop, install and operate complex software systems in support of clients across PNNL's customer base. The expertise in our group includes systems architectures, software systems engineering, software systems development, and data and information management for large and diverse data (streaming and static).

Our iterative (ongoing) lifecycle systems approach—combining project management and software development with data management—ensures a synergistic benefit to the overall product by involving the client and appropriate subject matter experts throughout the project.

The group delivers capabilities and expertise in the following areas:

Areas of Expertise

  • Client Relationship/Advocate/Analyst – the capability to bridge technical and non-technical communications
  • Strategic Partnerability to provide high-value, strategic input based on a detailed understanding of client software systems and data
  • Complete Software Systems Engineering Lifecycle (proposal, analysis, design, development, testing, implementation, operations) in an iterative manner that can be scaled to any size project
  • Project/Task Management – the ability to manage scope, schedule and budget at all levels
  • Software Integrationability to seamlessly integrate software as a component of a larger deliverable
  • Classified Projects experience with classified software and data
  • Software Prototypes, Proof of Concepts
  • Technology evaluations
  • Rapid Prototyping – the ability to provide initial, quick-turnaround interpretations of requirements
  • Software Architectures experience and knowledge required to define strategic technical direction, coordinate and integrate technical components
  • Software Development a broad range of programming environments including the two most popular—MS .NET and JAVA
  • Data Models, Database Design, Database Development focuses on data flows, calculations, management and dissemination
  • Collaborative User Interaction Design (GUI) – the ability to design a set of screens that are easy and intuitive
  • Data Analysis – the ability to transition from data to information to knowledge
  • Data Quality – the ability to identify inconsistencies and incompleteness in collected data and define methods to both update the data to be consistent/complete and prevent reoccurrence.
