Building a Data Strategy

Strategy Is Not Tool Selection

The most common mistake in engineering data strategy is starting with tools. "We need Teamcenter" is not a strategy. "We need to reduce the time from design change to manufacturing impact assessment from three weeks to three days, which requires structured BOM data with automated change propagation" is moving toward a strategy. The first is a purchase order. The second is a capability target with measurable criteria that will inform tool selection, process design, and organizational change.

A data strategy is a plan for how engineering data will be structured, governed, connected, and used across the lifecycle. It answers four questions that most organizations have never explicitly asked:

What data do we need? Not what data do we have — what data do we need, in what structure, at what quality level, to support the engineering decisions we make? Most organizations have far more data than they can use and far less of the data they actually need.

Who creates, owns, and governs it? Every data element needs a clear owner responsible for its accuracy and currency. Every transition between owners needs a defined handoff process. Data without governance is data without trust.

How is it connected? Which data elements need to trace to which other elements? What are the critical associations across the lifecycle? Where are the connections automated and where are they manual?

How do we measure progress? What metrics tell us whether our data is getting more structured, more accessible, and more connected over time? Without measurement, "improving data management" is an aspiration, not a program.

Five Dimensions of Data Maturity

Data maturity is not a single scale. An organization can be advanced in one dimension and primitive in another. Assessing where you are requires evaluating each dimension independently.

Structure. Is your engineering data typed, attributed, and queryable — or is it locked in documents? A requirement stored as a structured record with typed fields (ID, shall statement, threshold, verification method, allocation, status) is structured data. The same requirement written as a paragraph in a Word document is unstructured. Structure determines whether computation can operate on your data or whether a human must read it first.

Traceability. Can you follow an engineering artifact from its origin to its current state across the lifecycle? Given a field failure, can you trace backward to the requirement, the design analysis, and the test that should have caught it? Given a requirement change, can you trace forward to identify every affected artifact? Traceability is the thread — and it either exists at each transition or it does not.

Accessibility. Can all stakeholders access the data they need, in the format they need it, when they need it? A thermal analyst should be able to pull current geometry and material properties from the design model without requesting an export from the CAD team. A manufacturing engineer should see the released BOM without waiting for a data package. Accessibility does not mean universal access — it means role-appropriate access with minimal friction.

Governance. Are there clear rules for who creates, modifies, approves, and retires data? Is there a change control process? Is there an audit trail? Is there an authoritative source of truth for each data type? Governance is what makes data trustworthy. Without it, an organization has data — but cannot be certain that the data is accurate, current, or complete.

Integration. Are your tools connected, or do engineers manually transfer data between them? Every manual transfer is a potential error, a potential delay, and a thread break. Integration maturity ranges from fully manual (export-import cycles) to automated with live links (changes in one tool propagate to connected tools in real time).

Data Maturity Assessment: From Ad-Hoc to Optimized

StructureData lives in documents, spreadsheets, and personal drives. No common schema. Each engineer organizes data their own way.
TraceabilityTraceability exists only in engineers' heads. When someone leaves, the trace is lost. No tool-supported links between artifacts.
AccessibilityGetting data from another team requires knowing who to ask and waiting for them to send it. Shared drives with no organization.
GovernanceNo formal change process. Anyone can modify any file. 'Latest' means 'whatever I last saved.' No audit trail.
IntegrationAll data transfer is manual: export, email, re-enter. Engineers spend 30-40% of time on data handling, not engineering.

Use the slider to move through the three maturity levels. Most organizations will recognize themselves as somewhere between Ad-Hoc and Managed, with different dimensions at different levels. Very few organizations have reached Optimized across all five dimensions — but knowing the target is essential for building a roadmap.

How to Assess Where You Are

Assessment starts with honest inventory, not aspiration. For each of the five dimensions, answer concrete questions:

Structure. Pick your ten most critical engineering data types (requirements, CAD models, BOMs, test results, etc.). For each one: Is it stored as structured data in a managed system, or as a document on a file share? Can you query it computationally, or must a human read it?

Traceability. Pick three lifecycle transitions (requirement-to-design, design-to-manufacturing, test-to-requirement). For each one: Does a maintained, verifiable link exist? Is it automated or manual? When was the last time someone audited its accuracy?

Accessibility. Ask five engineers from different disciplines: "When you need data from another team's tool, how do you get it and how long does it take?" The answers will reveal the true state of accessibility, which is almost always worse than the data architecture diagram suggests.

Governance. Trace one recent engineering change from initiation to full implementation. Did it follow a defined process? Was the impact assessed across domains? Was the implementation verified? Was the thread updated? If any of these steps were skipped or informal, governance has gaps.

Integration. Map your critical tool-to-tool data flows. For each one: Is it automated, semi-automated, or manual? When the source tool updated its version last year, did the integration survive? How many hours per month do engineers spend on data transfer activities?

Building a Roadmap

Assessment reveals gaps. A roadmap closes them — incrementally, not all at once.

Start with the highest-pain integration point. Every organization has one data handoff that everyone complains about. The BOM that takes three weeks to translate from engineering to manufacturing. The requirement-to-test trace that nobody trusts. The simulation inputs that are always out of date. Start there. Fix one integration well and you demonstrate value, build capability, and learn what works before scaling.

Standardize the data model before connecting tools. Connecting two tools that use different data models just propagates confusion faster. Before building an integration, agree on what the shared data elements are, what attributes they carry, and what "current" and "approved" mean in both systems. This alignment work is unglamorous and difficult. It is also the foundation on which everything else rests.

Connect tools incrementally. Each integration should be scoped, tested, and stabilized before adding the next one. A fully connected toolchain built all at once is a house of cards. An incrementally connected toolchain is a progressively strengthened network.

Measure progress. Define metrics for each dimension and track them quarterly. Percentage of requirements with verified design links. Average time from change approval to manufacturing implementation. Number of manual data transfers per program per month. Metrics make progress visible and gaps actionable.

The Connection to Digital Engineering

A mature data strategy is what makes the digital thread possible. The thread is not an abstraction — it is the set of structured, governed, traceable, accessible, integrated connections between engineering artifacts across the lifecycle. Every dimension of data maturity maps directly to a thread capability:

  • Structure enables computation to operate on your data — the "logical and numerical associations" in the DE definition
  • Traceability is the thread itself — the connections that span lifecycle phases
  • Accessibility ensures that the thread is usable, not just existent
  • Governance ensures that the thread is trustworthy
  • Integration ensures that the thread is continuous across tool boundaries

Without structured, governed, accessible data, computation and AI have nothing to work with. You cannot run a machine learning model on PDF attachments in email threads. You cannot automate impact analysis on BOMs maintained in spreadsheets. You cannot form associations across information streams that are locked in incompatible formats behind organizational walls.

The data strategy is where the aspiration of digital engineering meets the reality of organizational practice. It is the least glamorous and most consequential investment an engineering organization can make.

Assessment

Question 1 of 3Score: 0

An organization has deployed a PLM system for CAD and BOM management, implemented OSLC links between their requirements tool and PLM, and established a change control board. However, simulation results are still stored on shared drives and test data is in an unconnected lab database. Which data maturity dimensions are most impacted by these gaps? (Select all that apply)

Select all that apply

Assess your own organization's (or one you are familiar with) data maturity across the five dimensions: structure, traceability, accessibility, governance, and integration. For each dimension, place the organization at one of the three maturity levels (Ad-Hoc, Managed, or Optimized) and provide one specific piece of evidence supporting your assessment. Then identify the single dimension where improvement would deliver the greatest impact, and propose one concrete action (not a tool purchase) that would move that dimension one level higher within 12 months.
