How We Work

At Sentient Digital, we apply a series of management threads and industry best practices from both the private and government sectors to deliver effective and efficient digital solutions to our clients.

Playbook: Execution, Assets, Tools, Management

SDi Playbook

The SDi Playbook describes our series of integrated management threads, process areas, and assets for building and delivering quality solutions for our clients. Using the SDi Playbook, various solution modules are synchronized into a single, well-rounded delivery strategy to meet our clients’ specific needs. Our framework is a customized approach, ensuring that transformations are thoroughly, smoothly, and effectively implemented with lasting and engrained benefits.

Through assimilation of industry best practices (CMMI®, SEI, PMBOK®), defense acquisition standards, and execution for clients, our playbook incorporates industry-standard methodologies to produce a roadmap in alignment with our clients’ visions for their organizations. The industry-standard methodologies including Agile, DevSecOps, and Rational Unified Process (RUP) to support our clients’ shift to a modern technology environment.

We drive the adoption and scaling of digital and technology initiatives through the integration of solution delivery lifecycle management (SDLM), delivery management, quality management, and technical management practices into our service strategies and client roadmaps. Our roadmap is flexible, iterative, and focused on increased quality and reduction of risk across our clients’ investment lifecycles—from initiation and development, to deployment and closure.

SDLC Management: Explore, Realize, Operate, Delivery Management, Quality Management, and Technical Management

Solution Delivery Lifecycle Management (SDLM)

Through exploration, realization, and operation processes, SDLM encompasses our practices related to project development. These span the full lifecycle of a project, from requirements engineering and cybersecurity planning, to data modeling and solution development and testing, into transition.

Delivery Management

Delivery management describes the various procedures and regular processes that ensure our projects remain relevant to our clients’ needs, on schedule, and efficiently executed. These processes include project initiation, planning, estimation, monitoring and control, risk and issue management, supplier agreement management, change control, decision analysis and resolution, as well as project closure.

Resource Management

Resource Management

Manages resource allocation and resource capacity across the project to ensure effective utilization.

Quality Control

Quality Control

Provides quality assurance and quality control through utilization of established standards and development of project management templates and execution of deliverable reviews.

Risk Issue Management

Risk and Issue Management

Supports projects by identifying and evaluating risk and issues, managing project scope, and escalating items, as needed.

PMO Functions: Resource Management, Governance, Schedule Management, Financial Management, Risk & Issue Management, Quality Control


Provides decision making framework to uphold accountabilities and responsibilities and identifies key stakeholders to act as an approval/escalation path.

Schedule Management

Principles of Quality Management

SDi is committed to delivering the highest quality products to our customers. As part of this commitment, our Quality Management System is formed on the basis of seven principles:

Technical Management

Our project teams are expected to understand and work within these fundamental building blocks for engineering solutions, regardless of the specific project lifecycle methodology used (waterfall, agile, or DevOps).

Our solutions are developed effectively when:

  • Solutions are defined conceptually
  • User needs are transformed into requirements
  • User needs inform how we develop and assess architectures

Our solution teams compose and assess alternative design and development approaches; develop test and certification strategies; monitor and assess efforts in design, development, integration, and test; and assist with field deployment, operations, and maintenance.

All of our systems engineering models and processes are organized around our lifecycle. Although the detailed views, implementations, and terminology used to articulate the SE lifecycle differ across SDi customers, they all share these fundamental elements.
