IT Staffing Glossary

Staff augmentation is a model where external IT professionals join an internal team to increase capacity, support delivery, or provide specialized skills while the client retains full control of the work.

Contract staffing refers to hiring IT professionals for a defined period of time to complete specific tasks or support ongoing projects without long-term employment commitments.

Contract-to-hire allows an employer to bring in a contractor temporarily with the option to convert them to a full-time employee after evaluating culture fit, technical ability, and performance on real work.

Direct hire is when an employer brings on a full-time employee immediately, with a staffing firm handling sourcing, screening, and recruiting.

A Statement of Work is a project-based staffing model where the staffing partner provides talent to deliver specific outcomes, milestones, or deliverables according to predefined scope, timelines, and pricing.

Managed services involve outsourcing ongoing IT functions or processes to a third-party provider who takes responsibility for performance, staffing, and delivery under a structured agreement.

A VMS is software used by large organizations to manage staffing vendors, job requisitions, candidate submissions, timesheets, compliance, and billing.

An MSP manages a company’s contingent workforce program by overseeing vendors, standardizing processes, improving compliance, and optimizing staffing performance across the organization.

A talent pipeline is a pool of qualified candidates who are pre-screened and ready to be engaged for future hiring needs, helping employers fill roles faster.

Talent acquisition is the strategic function of identifying, attracting, and hiring skilled professionals, including long-term workforce planning and employer branding—not just recruiting.

Technical recruiting focuses on sourcing and hiring candidates for technology roles such as developers, engineers, data specialists, cybersecurity experts, and IT project leaders.

An IT contractor is a technology professional hired for a temporary assignment to support specific initiatives, provide specialized skills, or augment internal teams.

A W-2 contractor is employed by a staffing firm, paid on a W-2 basis, and receives applicable taxes withheld—often with access to benefits like health insurance through the agency.

A 1099 contractor is a self-employed individual who provides IT services independently and is responsible for handling their own taxes and benefits.

Corp-to-Corp is a contractor engagement where an individual works through their own incorporated business or another consulting company, typically for specialized technical roles.

Bench talent refers to candidates who are already vetted, approved, and available to start quickly because they are between assignments with a staffing firm.

A contingent workforce is a flexible labor pool that includes contractors, freelancers, consultants, and temporary workers who support an organization’s needs without permanent employment.

An agency fee is the cost paid to a staffing partner for sourcing, screening, and placing a candidate—typically used in direct hire or project-based engagements.

The bill rate is the hourly rate a staffing agency charges the client for a contractor’s work. It includes pay rate, taxes, benefits, and agency margin.

The pay rate is the hourly wage paid directly to a contractor for their work. It is one component of the total bill rate charged to the client.

Markup is the percentage added to a contractor’s pay rate to determine the bill rate. It covers agency costs such as recruiting, payroll, taxes, benefits, and margin.

Redeployment occurs when a contractor finishes an assignment and is placed into a new role by the same staffing partner—improving retention and reducing ramp time.

Time-to-start tracks the period from candidate selection to the contractor’s first productive day. It captures onboarding friction caused by background checks, compliance, provisioning, and internal approval cycles.

Time-to-hire is the total time from initial candidate engagement to offer acceptance. Unlike time-to-fill, which begins at the requisition, time-to-hire measures the efficiency of the interview and decision-making process.

Quality of hire evaluates how effective a new contractor or employee is once onboard. It considers productivity, communication, reliability, culture fit, and impact on team performance. High QoH reduces turnover and accelerates delivery.

Retention rate measures the percentage of contractors who complete or extend their assignments. High retention reduces churn, maintains knowledge continuity, and lowers replacement costs.

Contractor conversion rate represents the percentage of contract workers who are hired full-time. A high CTR indicates strong matching, positive performance, and a reliable pipeline of long-term talent.

Ramp time is the period needed for a new contractor to reach full productivity. Low ramp time suggests effective vetting, strong onboarding, and clear expectations from both the staffing partner and hiring manager.

This ratio compares the number of candidate submissions to the number of interviews requested. A lower ratio signals precise sourcing, clear alignment between hiring managers and the staffing firm, and fewer wasted cycles.

Delivery velocity measures the pace at which engineering or project teams execute work. Staffing impacts velocity by increasing capacity, reducing burnout, and aligning skills to sprint and roadmap requirements.

Cost per hire includes all expenses involved in filling a role: recruiting time, tools, interviews, background checks, lost productivity, and vendor costs. Staffing often lowers CPH for rare or highly technical roles.

Cost per contractor calculates the full hourly cost of a contract resource, including pay rate, taxes, benefits, agency markup, and administrative overhead. It’s used for budgeting and vendor comparison.

Attrition measures how often contractors leave roles before assignment completion. High attrition increases cost, disrupts projects, and weakens team stability.

The renewal or extension rate indicates how often contractors are extended beyond their original assignment. High renewal rates reflect strong performance, good fit, and ongoing business needs.

Workforce planning is the strategic process of forecasting future talent needs based on business objectives, project pipelines, skill gaps, and resource constraints. It helps leaders plan staffing models proactively.

Resource forecasting predicts the number and type of IT professionals needed to support upcoming work. It helps avoid staffing bottlenecks and improves budget planning.

Utilization rate measures how much of a contractor’s capacity is used for productive work. High utilization ensures teams are properly staffed and resources are allocated efficiently.

Talent matching algorithms are AI-powered systems that compare job requirements with candidate profiles to predict the best fit. These algorithms evaluate skills, work history, and behavioral indicators to surface high-probability matches quickly.

Skill adjacency refers to related or neighboring skills that qualify a candidate for roles beyond their exact past titles. AI maps adjacency (e.g., Python + Kubernetes → ML pipeline potential) to expand talent pools and uncover hidden technical matches.
