What is Octave Sequence Enterprise for Project Performance?
Octave Sequence Enterprise (formerly EcoSys) is an enterprise project and portfolio performance platform built for capital-intensive organizations that need more than visibility; they need control.
From portfolio strategy to field execution, Sequence Enterprise connects investment planning, cost, schedule, scope, risk, contracts, change and performance data in one trusted project system. It gives owners, EPCs and program leaders managing complex assets, sites, extensive portfolios and megaprojects a single environment to align capital with strategy and execution with accountability.
Cost certainty. Forecast accuracy. Cross-functional collaboration. In high-stakes environments, these are non-negotiable. Sequence Enterprise, with 20+ years of best practices and customer collaboration, is built to deliver them at scale.

Process areas supported by Sequence Enterprise
Sequence Enterprise spans the full project lifecycle, connecting strategic planning with day‑to‑day execution.
Project portfolio management (PPM)
Capital doesn’t stretch endlessly. Resources are finite. Priorities compete. Risk compounds. The organizations that win aren’t the ones running more projects; they’re the ones running the right projects. Sequence Enterprise sharpens portfolio decisions by linking strategy directly to live project data. Owners managing multiple assets. EPCs balancing complex client programs. Both need visibility across cost, risk, capacity and return. That’s what integrated portfolio management delivers.
With Sequence Enterprise, you can:
Align investments to strategy
Prioritize initiatives based on value, risk and capacity so capital flows where it drives measurable impact.
Standardize governance at scale
Apply consistent controls, workflows and performance metrics across portfolios, programs and regions.
Replace manual reporting with real insight
Eliminate reconciliation work via automated roll-ups and role-based dashboards, surfacing what matters: forecast health, risk exposure and performance trends.
Automate repeatable processes
Streamline portfolio reporting, approvals and updates to reduce friction and accelerate decisions.
The result? Portfolio clarity backed by trusted project data. Not guesswork. Not spreadsheets stitched together at quarter-end. Real intelligence guiding capital where it performs best. Strategy aligned. Capital optimized. Performance scaled.
Project controls & project management
Projects don’t fail overnight. They drift. Costs creep. Schedules slip. Risks compound. Sequence Enterprise improves customer performance by uniting project controls and project management in one connected system, so teams can measure accurately, forecast confidently and act early.so teams can measure accurately, forecast confidently and act early.
With Sequence Enterprise, you can:
Measure performance with precision
Real-time cost, schedule and resource tracking grounded in consistent governance.
Forecast before issues escalate
Early warning indicators and forward-looking analytics help you course-correct before overruns take hold.
Manage change in context
Link risks, trends and variations directly to financial and schedule impacts, so responses are informed, not reactive.
Standardize execution at scale
Apply consistent workflows and controls across projects, programs and regions to improve predictability.
The result? Fewer surprises. Stronger forecast confidence. Delivery you can defend. Measure. Forecast. Control. Then scale that discipline across the enterprise.
Project planning, scheduling & estimating
Planning sets expectations. Scheduling creates the roadmap. Estimating defines the cost and resource boundaries. Without all three aligned, execution becomes guesswork.
Sequence Enterprise brings project planning, scheduling and estimating into the same system as cost, risk, change and performance data, so plans don’t live in isolation from reality.
With Sequence Enterprise, you can:
Build dependable plans
Develop scopes, budgets and resource requirements that reflect organizational standards and execution realities.
Connect schedules to performance
Integrate with industry scheduling tools or leverage out-of-the-box capabilities alongside cost and risk data to ensure forecasts and progress are synchronized.
Estimate with confidence
Use historical data to produce consistent, defensible estimates across projects and portfolios.
By unifying planning, scheduling and estimating with real-time performance data, Sequence Enterprise turns static plans into living roadmaps that guide execution and inform decisions.
Earned value management
Tracking progress isn’t enough. True control depends on comparing what’s planned with what’s delivered and understanding the deviation in both cost and schedule. Sequence Enterprise embeds earned value management (EVM) so organizations can quantify performance and productivity holistically, before overruns become losses.
With Sequence Enterprise, you can:
Establish baselines you can trust
Set cost, schedule and scope baselines that serve as defensible performance targets.
Measure actuals against plan
Integrate progress data with cost and schedule to calculate earned value metrics like BCWP (EV), BCWS (PV), ACWP (AC) and variances, all in real time.
Forecast impact with clarity
Use performance indices (CPI, SPI) and variance analysis to project outcomes, adjust forecasts and support recovery decisions earlier.
Report with confidence
Standard EVM metrics and dashboards make it easier to communicate performance to executives, partners and stakeholders.
Sequence Enterprise turns performance data into insight you can act on. You don’t just see the gap; you understand its implications and can respond with precision.
Budgeting & forecasting
Budgets set expectations. Forecasts track reality. The gap between them determines outcomes. In complex capital environments, you need both simultaneously; accurate, flexible and forward-looking. Sequence Enterprise unifies budgeting and forecasting with real performance data, so organizations can plan cash flow, anticipate risk and adjust course before outcomes diverge.
With Sequence Enterprise, you can:
Build defensible budgets
Capture detailed cost breakdowns, align to organizational standards and establish funding baselines you can stand behind.
Forecast with clarity
Drive rolling forecasts that incorporate actuals, trends and what-if scenarios, giving true forward insight.
Analyze variances quickly
Compare forecasts to budgets and actuals across cost, schedule and scope to understand why performance diverged and what it means for future results.
Improve predictability
Automate routine forecast updates, link assumptions to outcomes and empower teams with data that’s consistent, connected and current.
Sequence Enterprise transforms budgeting and forecasting from static exercises into ongoing guidance, improving confidence, shortening cycles and helping teams act before small variances become large overruns. Plan with precision. Forecast with confidence. Execute with foresight.
Capital budgeting & funding
Strategic capital planning is where investment intentions become execution reality. Decision makers must know which initiatives should be funded, when and how much drives confidence in outcomes.
Sequence Enterprise brings capital budgeting and funding into the same system that governs performance, so decisions at the funding table are grounded in real execution data, not isolated estimates.
With Sequence Enterprise, you can:
Evaluate capital needs with precision
Define and compare investment proposals against strategic priorities, risk profiles and available funds, so you invest where impact is highest.
Plan funding across horizons
Build multi-year capital plans and phased funding strategies that align with forecasted costs, cash flow constraints and enterprise goals.
Govern funding with clarity
Track authorization thresholds, funding releases and spend commitments in one controlled environment, not fractured spreadsheets.
Connect funding to performance
Link capital allocations directly to project cost, forecast, change and risk data to ensure the money you budget drives the outcomes you expect.
Sequence Enterprise doesn’t just plan budgets. It links capital intent to project reality, creating a funding process that’s transparent, defensible and aligned with execution performance. As a result, organizations prioritize wisely and fund confidently.
Resource planning & management
Resources are where strategy meets execution. People and equipment are the engines of delivery and when they’re misaligned, performance falters. Sequence Enterprise brings resource planning and management into the same system that drives project and portfolio performance, so capacity decisions are grounded in real demand.
With Sequence Enterprise, you can:
Align resource demand with supply
Forecast labor and equipment needs across projects and portfolios to reveal shortages, surpluses and conflicts before they impact execution.
Balance competing priorities
Allocate resources across concurrent initiatives, regions and asset types while managing constraints and strategic priorities.
Connect resources to cost and schedule
Link resource assignments directly to budgets, forecasts and schedule milestones, so utilization, availability, productivity and cost are visible in one place.
Standardize resource controls
Apply consistent role definitions, rate structures and assignment rules across teams and geographies to reduce variability and improve predictability.
Sequence Enterprise turns resource planning from manual scheduling and guesswork into capacity intelligence, enabling organizations to deploy the right people, equipment and skills at the right time.
Contract management
Contracts drive commitment. They define scope, risk and reward. But in complex environments (involving multiple vendors, change orders, variations and claims) contracts can become a source of friction instead of control. Sequence Enterprise brings contract management into the same performance platform that governs cost, change, risk and execution. The result: contract decisions are informed by project realities, not siloed documents or disconnected tools.
With Sequence Enterprise, you can:
Maintain clarity over commitments
Capture contract terms, deliverables and obligations in a controlled, searchable environment, so nothing slips through the cracks.
Track variations and change orders
Link contractual changes directly to cost and schedule impacts, ensuring financial and execution consequences are visible and traceable.
Manage payment and cash flow
Support progressive invoicing, payment certification and milestone tracking so financial commitments align with performance.
Standardize contract controls
Apply consistent approval workflows, compliance checkpoints and audit trails to improve governance and reduce disputes.
Sequence Enterprise eliminates contract ambiguity by connecting commitments to performance data, giving teams clarity, control and defensible outcomes. As a result, owner/operators, EPCs and other vendors achieve true alignment.
STO long-range planning
Shutdowns, turnarounds and outages (STO), also known as TAR events, are high-stakes delivery events where timing, safety and coordination matter as much as cost and compliance. These events compress scope, resources and risk into tight windows, which makes precision planning and real-time performance insight essential.
Sequence Enterprise brings STO planning into the same performance backbone that governs projects and portfolios, so every decision is anchored in current cost, schedule, risk and resource data.
With Sequence Enterprise, you can:
Play the long game
Connect asset intelligence via asset management systems to multi-year STO planning. As a result, organizations can forecast early, budget accurately and turn TAR events into opportunities for performance gains, not just necessary downtime.
Plan with purpose
Scope work by unit, discipline, system or asset with visibility into cost, resource demand and schedule impact before committing to a plan.
Sequence Enterprise removes blind spots from STO events by merging long-term planning, execution and controls into a unified system. As a result, teams execute with confidence.
Document management (coming Summer 2026)
Projects fail when information is fragmented. Documents stored in silos slow decisions, introduce rework and fracture accountability. Sequence Enterprise changes the equation by embedding document management capabilities into it’s platform. Now, Sequence Enterprise doesn’t just link documents to objects, it makes documents a first-class part of how work gets done.
With Sequence Enterprise, you can:
Store and access documents in context
Keep project and business documents where they belong. Link to scopes, changes, risks, contracts and execution events, so relevant content is always where teams need it.
View without opening new tools
Preview and consume content directly in Sequence Enterprise. Eliminate the need for a separate document management system and eradicate information silos.
Relate documents to performance objects
Connect files to project milestones, forecasts, change orders and risks. Documents aren’t separate artifacts; instead, they become verifiable inputs to decisions.
Support controlled workflows
Enable structured review and approval processes for RFIs, submittals, transmittals and other critical content with full audit trails.
Improve compliance and traceability
Capture metadata, version history and access activity, so compliance isn’t an afterthought; it’s built into how work is shared and controlled.
Sequence Enterprise turns documents from passive references into living, governed assets. As a result, teams reduce friction, improve clarity and connect information to outcomes.
Field Reporting
Execution lives in the field. When site activity is captured in notebooks, spreadsheets or disconnected tools, visibility breaks down, risk increases and leadership reacts too late. Sequence Enterprise changes the equation by embedding field reporting directly into the enterprise performance platform. The solution is also provided via a mobile app for easier use on site. Now, field activity isn’t documented separately from project controls; it becomes a first-class part of how work is governed, monitored and improved.
With Sequence Enterprise, you can:
Record daily logs and progress in context
Capture structured daily reports, production updates and field summaries that feed directly into performance metrics and forecasts.
Strengthen safety oversight with Near Miss Reporting
Document safety observations, incidents and near misses in real time, improving proactive risk management and reinforcing a culture of accountability.
Manage Non-Conformance Reporting (NCR) with control
Track quality and safety non-conformances (internal and external) with governed workflows, audit trails and direct linkage to responsible stakeholders.
Control inspections through Request for Work Inspection (RFWI)
Create, submit, approve, reinspect and track RFWIs within defined workflows, maintaining full visibility from initiation to final status.
Govern approvals without slowing execution
Route field logs, inspections and NCRs through structured review and approval processes that enforce compliance while maintaining momentum.
Surface real-time field intelligence
Provide dashboards and summaries that connect site-level activity to portfolio-level oversight, ensuring leaders see risks and trends as they develop.
Sequence Enterprise turns field reporting from isolated documentation into connected performance intelligence. When safety events, inspections, quality observations and daily progress are tied directly to cost, schedule and risk, leadership gains true situational awareness—not delayed summaries. The result: faster escalation, stronger compliance, defensible audit trails and aligned execution from the job site to the executive dashboard. Because what happens in the field should immediately inform what happens next.
Revenue Management
Margin erosion often starts with disconnects between scope and billing, change and recognition, forecast and cash flow. When revenue is tracked outside the core performance system, visibility weakens and control slips. Sequence Enterprise changes the equation by embedding revenue management directly into the platform. Now, revenue isn’t tracked separately from execution, it becomes a first-class part of how projects are governed and delivered.
With Sequence Enterprise, you can:
Budget revenue with structure
Define revenue plans aligned to contract terms, milestones and scope commitments, establishing clear financial expectations from the start.
Manage revenue changes in context
Integrate approved scope variations and contract modifications directly into revenue projections, ensuring financial impacts are immediately visible.
Forecast revenue with confidence
Incorporate actual performance, schedule updates and change events into rolling revenue forecasts, so projections reflect reality, not assumptions.
Support timely revenue recognition
Align earned revenue to project progress and contractual agreements, enabling accurate financial reporting and predictable cash flow.
Track payments and close out cleanly
Maintain visibility into billing, credits and final reconciliations, ensuring financial obligations are fulfilled and documented through project completion.
Sequence Enterprise turns revenue from a back-office activity into integrated performance intelligence. As a result, teams protect margin, improve cash flow visibility and ensure that what’s delivered in the field aligns with what’s recognized on the balance sheet.

Why the Name Change: From EcoSys to Sequence Enterprise
A new chapter deserves a name that reflects it.
As part of the transition from Hexagon to our standalone company, Octave, we are evolving the EcoSys name to Sequence Enterprise. This change isn’t about reinvention. It’s about alignment – bringing our product portfolio under a unified Octave identity that reflects who we are and where we’re headed.
The name Sequence reflects the discipline of sequencing in music, arranging notes and patterns in a deliberate order to create structure, timing and impact.
In projects, performance follows the same principle. Success doesn’t come from isolated activities; it comes from coordinating scope, cost, schedule, resources and risk in the right order to drive optimal outcomes. Sequencing myriad project processes—capital allocation, procurement timing, field execution, approvals and change impacts—creates momentum and control.
Sequence Enterprise embodies that structured coordination: bringing the moving parts of complex planning and delivery into alignment so performance is intentional, not incidental.
And just as important: while the name evolves, the foundation remains.
Customers will continue to experience the depth, configurability, integrations, governance and performance capabilities they’ve relied on for years. The platform they trust isn’t going away. It’s moving forward with a name that better represents its role within Octave and its position in the enterprise landscape.
EcoSys built a reputation for enterprise-grade performance. Sequence Enterprise carries that legacy forward, with sharper alignment and a stronger connection to the Octave brand.
Same expertise. Stronger identity. Built for what’s next.
