Backlog Refinement

The ongoing practice of clarifying, splitting, estimating, and ordering items on a product backlog so the team always has a healthy queue of ready work for upcoming sprints or releases.

Agile

Burn-Down Chart

A time-series chart showing remaining work against time, used by agile teams to visualise sprint or release progress and forecast completion.

The disciplined process of combining the 3D models produced by design and trade contractors, detecting conflicts, and resolving them in a virtual environment before steel, ductwork, or pipe is fabricated and installed.

Procurement

Bid Leveling

The structured normalization of competing contractor proposals so price differences reflect real scope and risk differences — not gaps in what each bidder included.

Cost

Burn Rate

The speed at which a project consumes budget or capacity per unit of time — the single fastest indicator that cost or effort is drifting off plan.

Operations

Blameless Postmortem

A structured, no-fault review after an incident or failure focused on system and process causes rather than individual blame — the operating practice behind every mature reliability culture.

DevOps

Blue-Green Deployment

A release technique that runs two production environments — blue (current) and green (new) — and switches traffic between them, enabling near-zero-downtime deploys and instant rollback.

Agile / DevOps

Bug Triage

The regular, disciplined meeting where new defects are reviewed, classified, prioritised and assigned — the difference between a live product backlog and a graveyard of unresolved tickets.

C
Schedule

Assigning budgeted cost to each schedule activity so the time-phased schedule itself becomes the project budget baseline used for earned value and cash-flow forecasting.

IT / Reliability

Chaos Engineering

The disciplined practice of injecting controlled failures into a running system to expose weaknesses before real incidents do — proactive resilience testing at production scale.

Contract

Concurrent Delay

Two or more delay events, one owner-caused and one contractor-caused, running in the same window and each independently capable of delaying completion.

Delivery

Commissioning Plan

The structured document defining how a facility or system will be tested, verified, and handed over from construction to operations.

DevOps

Canary Release

A release technique that exposes a new version of software to a small subset of traffic or users first, so problems are detected on a limited blast radius before the full rollout.

Construction Execution

Concrete Pour Card

A single-page control document that authorises a specific concrete pour by confirming design, formwork, reinforcement, embedments, weather and inspection sign-offs are all in place before the truck arrives.

Quality

Concrete Cube Testing

The sampling, curing and crushing regime that proves a concrete pour actually reached its design strength — and the auditable chain of custody that makes those results defensible.

Software Engineering

Contract Testing

A testing strategy for services that talk to each other — each consumer records the shape of the responses it relies on, and the provider verifies against those recorded contracts on every change.

D

A short, focused, time-boxed daily meeting where the delivery team aligns on progress, plans the next 24 hours of work, and surfaces blockers.

Agile

Definition of Done

A shared, written checklist that defines what 'done' means for a unit of work — the single most important quality discipline in agile delivery.

Agile

DevOps

F
Schedule

Float Management

The deliberate planning and consumption of schedule float (slack) to absorb uncertainty and prioritise management attention.

Schedule

Forward Pass Scheduling

The CPM calculation that walks the network from project start to finish to determine the Early Start and Early Finish of every activity, establishing the earliest the project can possibly complete.

Agile

Feature Flag

A configuration-driven switch that lets teams turn software features on or off in production without redeploying — decoupling deploy from release and making rollback a single config change.

Cost Management

Force Account Work

Work performed on a time-and-materials basis — used when scope is too uncertain to price as a lump sum, with strict daily records to substantiate cost.

Schedule

Fragnet (Fragmentary Network)

A small, self-contained network of activities inserted into a baseline schedule to model a delay, change, or recovery scenario without disturbing the main logic.

IT

Feature Toggle

A software mechanism that lets code paths be turned on or off at runtime without redeploying — decoupling deploy from release.

A relative, unitless estimate of effort that captures complexity, uncertainty, and volume in a single number — and works only when teams resist the urge to convert them back into hours.

Performance

Service-Level Objective

A measurable reliability target — typically expressed as a percentage over a time window — that defines how reliable a service needs to be to satisfy users, and against which engineering trade-offs are made.

Schedule

Schedule Compression

Techniques to shorten the schedule without reducing scope — primarily crashing (adding resources) and fast-tracking (overlapping activities) — used when end-date pressure exceeds the original plan.

Design

Shop Drawing

A detailed fabrication or installation drawing prepared by the contractor, subcontractor, or supplier that translates design intent into buildable, dimensioned instructions.

Agile

Swarming

The practice of temporarily concentrating a whole team on a single high-priority item — story, incident, or blocker — until it is finished, rather than working many items in parallel.

Agile

Spike (Agile)

A time-boxed investigation used when a story cannot be estimated or designed without further research or prototyping.

Construction Execution

A short pre-delivery sprint used to establish the environment, tooling, backlog, and team norms needed before productive delivery sprints begin.

Agile

Story Slicing

The craft of breaking a large user story into smaller stories that each deliver end-to-end value, fit within a sprint, and can be independently accepted.

IT / Agile

A quantitative measurement of a service's behaviour — such as request success rate or latency at the 99th percentile — that expresses reliability in numbers the users actually experience.

Contract Administration

Site Instruction

A written direction from the contract administrator or engineer to the contractor to carry out, vary or clarify work on site — the contractual mechanism that turns a verbal decision into an enforceable action.

Health & Safety

Scaffolding Inspection Register

The statutory log of scaffold inspections — every seven days, after alteration, after weather — that determines whether the scaffold may be used, and who carries the legal risk if it is used when it should not be.

Construction Execution

Site Mobilization Plan

The staged plan for turning a raw site into an operating construction workplace — access, welfare, utilities, permits, security — sequenced so the first productive activity can start on the day the schedule assumes it will.

Contracts

Sectional Completion

A contractual mechanism that allows discrete sections of the works to reach practical completion — and to trigger their own damages, warranties and defect periods — independently of the rest of the project.

T
Schedule

Time-Impact Analysis (TIA)

A forward-looking schedule-delay analysis technique that quantifies the time impact of a specific change or delay event by inserting a fragnet into the current schedule.

Lean

Takt Time Planning

A lean production approach that paces work to a steady rhythm — the takt time — by sizing work zones so each crew finishes one zone in the same time, creating predictable flow.

Agile

Technical Debt

The accumulated cost of expedient engineering decisions — the metaphorical interest you pay every time you change a system that was built quickly rather than carefully.

Agile

Test-Driven Development

An engineering discipline of writing a failing test before the code that makes it pass — producing better-designed, better-tested software at a sustainable pace.

Cost

Trend Program

A structured forward-looking process to identify, value, and act on potential cost or schedule changes before they are formal change orders — the early-warning radar of capital projects.

Construction Execution

Temporary Works Register

A live schedule of every temporary structure on site — shoring, formwork, scaffolding, edge protection, cranes bases, propping — with designer, checker, load-case and removal date for each.

IT / Agile

Trunk-Based Development

A source-control practice in which all developers commit small changes to a single shared branch (trunk/main) at least daily, using feature flags rather than long-lived branches to manage in-progress work.

Health & Safety

Toolbox Talk

A short, focused pre-shift safety briefing led by the foreman on a single hazard relevant to the day's work — the most-used and most-abused safety communication tool on any site.

Agile Practices

Three Amigos Meeting

A short, focused conversation between a product person, a developer and a tester before a user story is committed — to surface ambiguity, agree on examples and shorten the feedback loop that would otherwise happen in code review.
