I find where your process leaks time and money, then rebuild it so the fix holds after I leave. On the last value stream I mapped, 40% of the steps added no value. Functional Lean Six Sigma Master Black Belt, 12+ years at GE and Genpact. I am Sona Murgai, Founder and Principal Advisor of Process Velocity Advisors LLC, and the author of Lean Management Essentials (Vibrant Publishers). I work with small businesses, mid-market companies and healthcare organizations whose operations are growing faster than the processes holding them up. At GE and Genpact I served as a functional Master Black Belt, Black Belt trainer and Master Coach, mentoring 200+ Green Belt and Black Belt projects, designing Black Belt training and certification assessments, and leading the Process Excellence function for the Consumer Goods, Pharma and Life Sciences business units of a global outsourcing firm. RECENT ENGAGEMENTS: ● Marketing agency, client account operations: replaced a legacy help-desk queue with a three-board workflow architecture in Asana. 7 request types standardized with named approvers, 6 disconnected systems brought under one intake and approval model, 0 downtime at cutover. ● Hospital staffing pilot: 90-day phased launch across 5 nursing departments. Baselined 7 KPIs where no measurement existed, designed the time and motion study to capture what the systems could not, then handed ownership to hospital HR and Operations against a documented transition playbook. ● Multi-state real estate investment firm: assessed 9 disconnected systems as they were actually used rather than as documented, gap-scored 6 operating domains, replaced person-based SOPs with a role-based RACI model. ● B2B medical distributor, quote-to-cash rebuild: quoting, purchasing and third-party fulfillment were running on tribal knowledge and email threads. Rebuilt as one system of record with documented sourcing decision rules, SOPs, and an integrated logistics workflow. HOW I WORK: ● Define the process and the success metrics before anything else ● Map the current state, exception paths included, so the team argues about a picture instead of about memories ● Analyze root causes with data, not opinions ● Improve: design changes your team can actually sustain once I am gone ● Control: measure against the baseline, then lock it in with SOPs, controls and dashboards ENGAGEMENTS I TAKE ON: ● Business process mapping, analysis and redesign ● Operational efficiency audits with a prioritized improvement roadmap ● SOP development and process documentation ● Workflow automation readiness: requirements, tool selection, and for healthcare, HIPAA and BAA compliance validation before you build ● Lean Six Sigma training and coaching: Green Belt and Black Belt mentoring, Black Belt curriculum design, Advanced Lean programs ● Project and change management for improvement initiatives I design and specify. When an engagement needs the technology built, I bring an established delivery partner and keep the design and the accountability with me, so you are never handed off. CERTIFICATIONS: Lean Six Sigma Master Black Belt (functional) · Certified Six Sigma Black Belt · Certified Advanced Lean Trainer · Black Belt Trainer and Master Coach · PMP (in progress) · Post Graduate Diploma in Business Management, MBA equivalent (IMI Delhi) Most engagements start with a fixed-fee Operations Diagnostic: a structured assessment that leaves you with a process map, findings and a roadmap you can act on, with me or without me. Message me with the operational problem you are facing. You will get specific questions back, not boilerplate.

Fractional Systems Engineer & Infrastructure Advisor Complex IT, Data Center & Delivery Systems Overview / Summary I work with organizations that operate complex technical environments and need clarity, stability, and credible decision-making, not surface-level explanations. My background is in systems engineering and large-scale technical operations, where infrastructure is not theoretical. It is power distribution, cooling, cabling, monitoring, automation, and governance operating under real constraints. Over the past two decades, I’ve worked across defense, enterprise IT, and modernization programs where reliability, transparency, and risk discipline matter more than speed or marketing narratives. Today, I support clients in three primary ways: • Explaining complex IT and data center infrastructure for technical and semi-technical audiences • Designing and auditing system-level delivery and governance models where failure carries real consequences • Translating engineering reality into executive-ready insight without diluting technical truth Clients tend to engage me when: • Oversimplification would be dangerous • Infrastructure needs to be understood as a system, not a checklist • Content, analysis, or guidance must reflect how environments behave in production I’m known for connecting the dots between physical infrastructure, automation, monitoring, and human decision-making — and for communicating those connections clearly to the people accountable for outcomes. What I’m Typically Hired For • Infrastructure & Systems Analysis Making complex environments intelligible across technical, operational, and leadership layers. • Technical Thought Leadership & Educational Content Producing accurate, credible material on IT infrastructure, data centers, automation, and systems governance. • Delivery & Governance Stabilization Helping organizations regain control when projects, platforms, or portfolios drift out of alignment. • Human-Centered Automation & Monitoring Strategy Designing automation and observability approaches that support — not replace — accountable human judgment. Selected Outcomes • Supported 200+ complex initiatives across regulated and high-risk environments • Helped organisations reduce rework and delivery friction through system-level modelling and clarity • Enabled executives and technical leaders to make better decisions by seeing infrastructure holistically • Delivered over $300K in consulting value through focused, high-trust engagements How Engagements Usually Work Most clients engage me in one of the following ways: • A diagnostic review of infrastructure, delivery, or governance challenges • A targeted advisory engagement focused on a specific technical or operational problem • A fractional advisory role supporting ongoing clarity, decision-making, or content development Engagements are typically milestone-based or retainer-driven, depending on scope and duration. Core Domains & Tools Systems Engineering • IT & Data Center Infrastructure • Infrastructure Monitoring & Observability Automation Strategy • Model-Based Delivery & Governance • Risk & Reliability Technical Writing & Thought Leadership • Executive Translation Microsoft 365 • PowerShell • SharePoint • Enterprise Collaboration Platforms Working Philosophy Technology should make systems clearer, not more opaque. Automation should elevate human judgment, not obscure accountability. Good infrastructure thinking respects reality — not just diagrams. If your organization needs someone who understands how complex technical systems behave in the real world — and can communicate that understanding with precision — we should talk.
