In Leonard E. Read’s famous essay “I, Pencil”, he illustrates the complexity behind even the simplest products, like a pencil, and highlights how no single individual can produce it alone. The essay showcases the intricacies of a global supply chain and the division of labor required to create something as basic as a pencil. Similarly, managing the lifecycle of a product – even something as seemingly simple as a pen – involves a wide range of interconnected tasks, from sourcing materials to managing designs and coordinating release schedules.
With Nora IPLM (Innovation and Product Lifecycle Management), managing each stage of a product’s lifecycle becomes simpler and more efficient, despite the complexity. Whether you’re tracking components, managing product changes, or mitigating risks, Nora IPLM helps bring all aspects of the pen’s development together in one seamless platform. Let’s explore how Nora IPLM optimizes each stage of the pen’s lifecycle, making it easier to manage the intricacies of product creation, from ideation to release.
Product Lifecycle Management Example: Managing a Pen
Product lifecycle management (PLM) is the discipline of controlling product information and processes from the first requirement through design, manufacturing, change, support, and retirement. A simple retractable pen provides a useful PLM example because it contains a product structure, materials, suppliers, drawings, revisions, manufacturing steps, variants, and changes – just like a more complex manufactured product.
PLM does not merely store the pen’s files. It connects the requirement for how the pen should work to the approved parts, engineering BOM, manufacturing definition, supplier information, release workflow, change history, and final product configuration.
What Is Product Lifecycle Management?
Product lifecycle management integrates people, product data, processes, and connected business systems across a product’s lifecycle. In manufacturing, PLM commonly governs items, technical documents, CAD files, bills of materials, revisions, configurations, requirements, engineering changes, approvals, supplier records, and engineering-to-manufacturing handoffs.
The purpose is to maintain a trusted product definition and a traceable way to release and change it. PLM helps teams answer: What is the approved product? Why did it change? Which products and processes are affected? When does the new definition apply?
Why Use a Pen as a PLM Example?
A pen is familiar enough to understand without specialist knowledge, yet detailed enough to demonstrate real lifecycle control. A retractable pen may include a barrel, grip, ink cartridge, tip, spring, plunger, clip, decorative parts, packaging, and manufacturing-specific materials. It can also have variants for ink color, barrel color, branding, market language, and package quantity.
The example is intentionally simplified. An actual manufacturer may manage additional tolerances, tooling, test specifications, regulatory evidence, costing, logistics, and quality records.
The Pen Product Structure
Each object can have a unique identifier, description, revision, lifecycle state, owner, documents, material, approved suppliers, and effectivity. The BOM records quantity and parent-child relationships.
PLM Example: Managing a Pen Across 8 Lifecycle Stages
1. Capture the Product Idea and Requirements
The lifecycle begins with a need: create a refillable retractable pen for office and promotional use. Requirements translate the idea into reviewable product intent.
- Write continuously and retract without leaking.
- Fit defined cartridge dimensions and writing-tip geometry.
- Meet target dimensions, grip range, appearance, and package requirements.
- Support blue, black, and red ink configurations.
- Use materials and labeling appropriate for intended markets.
- Allow a branded barrel without changing the writing mechanism.
PLM links requirements to design objects and later verification evidence. When a requirement changes, the team can identify which parts, documents, and tests may need review.
2. Create the Product Definition
Designers create part records, CAD models, drawings, specifications, and early prototypes. The barrel drawing defines dimensions and material; the spring specification defines geometry and force; the cartridge specification defines ink, capacity, interfaces, and tip compatibility.
PLM connects these files to controlled product objects. Work-in-progress iterations remain distinguishable from released revisions, and CAD references can stay related to the assembly rather than being exchanged as unrelated attachments.
3. Build and Control the Engineering BOM
The engineering BOM (EBOM) describes the pen as designed. It organizes components into a multi-level structure with quantities and approved revisions. Engineers can compare BOM versions, view where a component is used, and determine whether a proposed change affects one pen or several product variants.
- Barrel assembly: Quantity: 1; Example controlled information: Material, color specification, CAD model, drawing, branding interface..
- Ink cartridge: Quantity: 1; Example controlled information: Ink color option, capacity, tip interface, approved revision..
- Compression spring: Quantity: 1; Example controlled information: Wire material, dimensions, force range, supplier specification..
- Plunger and cam: Quantity: 1 set; Example controlled information: Geometry, fit, material, assembly relationship..
- Grip: Quantity: 1; Example controlled information: Material, texture, color option, drawing..
- Clip: Quantity: 1; Example controlled information: Material, finish, retention requirement..
- Packaging set: Quantity: 1; Example controlled information: Box or sleeve, label, artwork, market language..
4. Source Materials and Supplier Parts
Procurement and engineering evaluate suppliers for the cartridge, spring, polymer resin, ink, packaging, or contract-manufactured components. PLM can connect approved sources, supplier documents, specifications, qualification status, and change communications to the relevant part.
Supplier information should not replace ERP purchasing records. PLM governs the product and approval context; ERP usually manages purchasing, inventory, planning, and commercial transactions.
5. Transform the EBOM into an MBOM
The manufacturing BOM (MBOM) organizes the pen as it will be built. It may regroup engineering parts by operation and add manufacturing-only content such as bulk ink, adhesive, lubricant, printing consumables, labels, trays, or packaging materials.
- Molding and preparation: Example MBOM content: Barrel halves, grip, clip, resin, color masterbatch, printing preparation..
- Writing assembly: Example MBOM content: Cartridge, ink fill, tip, seal, inspection materials..
- Retraction assembly: Example MBOM content: Spring, plunger, cam, lubricant, functional test..
- Final assembly: Example MBOM content: Prepared barrel, writing assembly, mechanism, grip, clip..
- Packaging: Example MBOM content: Finished pen, label, leaflet, box or bulk tray..
The EBOM and MBOM do not need identical structures. They need traceability so a design change can be evaluated against the manufacturing definitions that use it.
6. Release the Pen for Production
A release workflow confirms that the required parts, drawings, specifications, BOMs, approved suppliers, manufacturing definitions, and verification evidence are complete. Reviewers may include product engineering, manufacturing, quality, procurement, and product management.
Once approved, lifecycle states and revisions identify the released baseline. ERP or MES can receive controlled product and manufacturing information through defined handoffs. PLM retains the decision history and source definition.
7. Manage Engineering Changes and Variants
After launch, the pen may need a different spring, a new ink formula, revised branding, or alternative packaging. A change request records the problem or opportunity. Impact analysis identifies affected BOMs, drawings, requirements, configurations, suppliers, tooling, manufacturing plans, and inventory considerations.
Configuration rules can maintain a common pen family while controlling choices such as ink color, barrel color, logo, market label, and packaging. Effectivity defines when a new revision or alternative becomes valid by date, lot, unit, plant, or configuration.
8. Support Quality and End-of-Life Decisions
Quality feedback may reveal leakage, weak clip retention, inconsistent spring force, or packaging damage. PLM can connect the issue to the applicable product configuration and released definition, helping teams investigate and initiate a controlled change.
At end-of-life, teams may manage a final production run, remaining service or warranty obligations, replacement products, supplier last-time buys, document retention, material information, and disposal or recycling instructions. PLM preserves the product record even after active production ends.
A Practical Pen Change Example
Suppose the current compression spring intermittently fails to extend the cartridge after repeated use.
1. Quality records the failure mode and attaches inspection evidence.
2. Engineering opens a change request linked to the released spring and requirement for reliable retraction.
3. Where-used analysis identifies every pen configuration and MBOM that uses the spring.
4. A revised spring geometry is evaluated; the part, drawing, and assembly references receive proposed revisions.
5. Manufacturing reviews assembly equipment, test criteria, WIP, and remaining stock; procurement reviews the supplier and lead time.
6. The change package is approved with a defined implementation point, such as a production lot or effective date.
7. The released BOM, MBOM, documents, and supplier information reflect the new revision while the previous definition remains
This is the practical value of PLM: the team does not merely replace a drawing. It controls the complete decision and its impact across the product lifecycle.
What Information Does PLM Connect?
- Requirements: Pen example: Retraction reliability, dimensions, ink options; Why the relationship matters: Shows the intent a design or change must satisfy..
- Items and documents: Pen example: Spring part, barrel drawing, cartridge specification; Why the relationship matters: Separates controlled product objects from their supporting files..
- BOMs: Pen example: EBOM and MBOM; Why the relationship matters: Connects design structure with production structure..
- Configurations: Pen example: Ink, barrel, branding, market, package; Why the relationship matters: Prevents uncontrolled copies for every sellable variation..
- Changes: Pen example: Spring revision or ink substitution; Why the relationship matters: Records reason, impact, approval, implementation, and resulting revisions..
- Suppliers: Pen example: Approved spring or cartridge source; Why the relationship matters: Connects sourcing evidence to the part and revision..
- Lifecycle states: Pen example: In work, under review, released, obsolete; Why the relationship matters: Shows whether information is proposed or approved..
- Effectivity: Pen example: Date, lot, plant, configuration; Why the relationship matters: Defines where and when a revision applies..
PLM vs the Marketing Product Life Cycle
Product lifecycle management is often confused with the marketing product life cycle. They are related but not identical.
- Product lifecycle management (PLM): Primary focus: Controlling the product definition, processes, and decisions across engineering and manufacturing.; Typical stages or records: Requirements, design, BOMs, revisions, changes, manufacturing, support, retirement..
- Marketing product life cycle (PLC): Primary focus: Managing market performance and commercial strategy over time.; Typical stages or records: Introduction, growth, maturity, and decline..
PLM can support information used during launch, growth, and retirement, but its core role is not to forecast market demand. It governs the technical and operational product record.
Which Systems Work with PLM?
- CAD: Primary role: Create geometry, drawings, and design references.; Pen example: Barrel assembly and spring drawings..
- PLM: Primary role: Control product structure, revisions, configurations, changes, and approvals.; Pen example: Released pen definition and change history..
- ERP: Primary role: Plan and transact materials, purchasing, inventory, costing, and orders.; Pen example: Purchase spring stock and plan production..
- MES: Primary role: Execute and record production operations.; Pen example: Run assembly, inspection, and packaging steps..
- QMS: Primary role: Manage quality processes and evidence.; Pen example: Investigate leakage or spring failures..
- CRM/service: Primary role: Manage customer and service interactions.; Pen example: Collect field feedback and warranty cases..
The exact system boundary varies by company. What matters is clear ownership and a controlled exchange of identifiers, revisions, statuses, and effectivity.
