ACRP-PM key terms

A written summary of what a clinical study will and will not deliver, including objectives, key endpoints, major deliverables, and explicit exclusions. It gives the team a shared boundary for judging whether new requests are in or out of scope.

Slow, unmanaged expansion of study work through small additions that were never formally approved or resourced. Each change looks minor, but the cumulative effect erodes timelines, budgets, and team capacity.

A hierarchical breakdown of all study work into progressively smaller deliverables and tasks. It defines the total scope, supports effort estimation, and provides the backbone for scheduling and cost assignment.

The longest sequence of dependent activities through the schedule, which sets the shortest possible study duration. Any delay on a critical-path task delays the whole project unless the plan is compressed or resequenced.

The amount of time an activity can slip without delaying a dependent milestone or the study finish date. Tasks with zero float sit on the critical path and need the closest monitoring.

A significant, zero-duration point in the schedule marking completion of a major deliverable, such as first patient in or database lock. Milestones give stakeholders simple checkpoints for tracking progress.

The approved version of the study timeline against which actual progress is measured. Changes to it require formal approval, so it stays a stable reference for variance analysis and reporting.

A bar chart that displays tasks against calendar time, showing durations, overlaps, and dependencies. It is a common visual tool for communicating the study timeline to sponsors and site staff.

A technique that compares planned value, earned value, and actual cost to measure schedule and cost performance objectively. It yields indices and variances that flag whether a study is ahead, behind, or over budget.

The difference between the approved study budget and actual spending at a given point. Investigators analyze it by category to find overspending drivers and decide whether corrective action or a forecast update is needed.

A cost model that prices study activities per enrolled or completed participant, often by visit. It links revenue and expense to enrollment volume and helps sites and sponsors forecast financial exposure as recruitment changes.

Expenses paid to third parties, such as central labs, imaging vendors, or institutional review boards, that are billed through without site markup. They are tracked separately because they are largely outside the site's control.

Selecting, contracting with, and overseeing external providers so their deliverables meet agreed quality, timeline, and cost terms. It includes clear specifications, performance metrics, regular reviews, and escalation when service levels slip.

A contract clause or document specifying measurable performance expectations for a vendor, such as query turnaround time or sample shipping windows. It defines how performance is measured and what happens when targets are missed.

Adjusting task start and finish dates to resolve conflicts when demand for people or equipment exceeds availability. It may shift the schedule or extend duration in exchange for a realistic, executable workload.

A bar chart showing how much of a resource, such as coordinators or monitors, is needed in each time period. It makes peaks and gaps visible so managers can rebalance assignments before work is affected.

A living log of identified study risks with their likelihood, impact, owner, mitigation plan, and current status. It is reviewed regularly so the team can act on threats before they become issues.

Actions taken in advance to reduce the probability or impact of an identified risk. Examples include backup vendors, contingency enrollment sites, or extra training, each assigned to a named owner with a due date.

A pre-agreed fallback describing what the team will do if a specific risk occurs. Having it written before the event shortens response time and reduces improvised decisions under pressure.

A record of problems that have already occurred, with owner, priority, action, and resolution date. Unlike risks, issues are current realities requiring active management and escalation when unresolved.

A document defining the quality standards a study must meet and how compliance will be verified, through monitoring, audits, and metrics. It translates protocol and regulatory requirements into concrete checks and responsibilities.

Planned, systematic activities that confirm the study is conducted and data are generated according to protocol, good clinical practice, and applicable regulations. It is process-focused and preventive rather than a final inspection.

Operational checks performed on specific outputs, such as source data verification or edit checks, to detect defects. QC finds problems in the product or data, while QA works on the system that produces them.

A structured response that fixes a detected problem and addresses the underlying cause so it does not recur. It includes root cause analysis, an action plan, an owner, a due date, and verification of effectiveness.

A method such as the five-whys or fishbone diagram used to trace a problem back to its underlying cause rather than its symptoms. It guides durable fixes and prevents repeated deviations.

A formal process for proposing, assessing, approving, and documenting changes to scope, schedule, or budget. It ensures impacts are understood and approved before work proceeds, preserving the integrity of baselines.

Identifying everyone affected by or able to influence the study, then mapping their interests and influence. The resulting picture guides how much and what kind of communication each group needs.

A documented approach defining who receives what information, in which format, how often, and from whom. It sets expectations for reporting cadence and reduces surprises for sponsors, sites, and oversight bodies.

The agreed chain of people to contact, and in what order, when a problem exceeds the team's authority or tolerance. It clarifies thresholds and timeframes so serious issues reach decision-makers quickly.

A chart assigning each task or decision to those Responsible, Accountable, Consulted, and Informed. It removes ambiguity about who does the work and who owns the final call.

A structured review capturing what worked and what did not, plus recommendations for future studies. Conducted at milestones and closeout, it turns experience into reusable organizational knowledge.

The final phase in which deliverables are accepted, contracts closed, records archived, and the team released. It confirms obligations are met and captures lessons before the study is formally ended.

A projection of how many participants will enroll each period, based on site start-up dates, historical rates, and screening assumptions. It drives timelines, budgets, and decisions about adding or replacing sites.

A quantifiable measure chosen to track whether a critical study activity is on target, such as enrollment rate or query resolution time. Good KPIs are few, actionable, and tied to defined thresholds.

The document that formally authorizes a study project, naming the sponsor, project manager, high-level objectives, and constraints. It anchors authority and gives later planning documents a reference point.

The interdependent trade-off among scope, time, and cost, with quality affected by all three. Changing one dimension usually forces adjustment in another, so trade-offs should be explicit and approved.

The integrated document describing how the study will be executed, monitored, and controlled across scope, schedule, budget, quality, risk, and communication. Subsidiary plans and baselines roll up into it.

A record of things taken as true for planning purposes without proof, such as expected site activation dates. Each assumption is tracked and validated so plans can be corrected if it proves false.

A plan describing how each stakeholder group will be kept involved and supportive, matched to their influence and interest. It goes beyond messaging to specify involvement activities such as advisory meetings or site forums.
