Full title and description

STB UNE-EN 60300-3-3:2017 — Dependability management — Part 3-3: Application guide — Life cycle costing. This document provides guidance on life cycle costing (LCC) within the dependability management framework, emphasising cost elements influenced by reliability, availability, maintainability and supportability and describing an LCC process, cost breakdown structures and financial evaluation techniques for decision making.

Abstract

This application guide explains the purpose and value of life cycle costing, outlines a step‑by‑step LCC process (establish context, plan the analysis, define approach, perform analysis, finalise), identifies typical life cycle cost elements, covers dependability‑related cost drivers and presents financial evaluation and sensitivity analysis techniques plus illustrative examples to support procurement, design and asset‑management decisions.

Scope

The standard gives a practical introduction to life cycle costing applicable to all industries where total cost of ownership and dependability are key decision drivers. It focuses on expense elements across life‑cycle stages (concept, development, realisation, utilisation, enhancement, retirement), clarifies how dependability attributes affect costs and provides guidance to plan and perform LCC studies to compare design, procurement and support options.

Key topics and requirements

• Overview of LCC concepts, objectives and applicability for dependability‑influenced decisions.
• Structured LCC process: establish context, plan analysis, define approach, perform analysis, finalise and document results.
• Cost breakdown structures (CBS) by life‑cycle stage and examples of typical cost elements (equipment, maintenance, spares, training, facilities, contractor services, disposal).
• Dependability‑related cost drivers: reliability, availability, maintainability and supportability impacts on operating and support costs.
• Financial evaluation techniques: discounted cash flow (DCF), internal rate of return (IRR), depreciation/amortisation, time value of money, taxation and opportunity cost.
• Methods for estimating cost elements (parametric, analogous, engineering), treatment of intangibles, sensitivity and uncertainty analysis, and worked examples/models.

Typical use and users

Used to support trade‑off and procurement decisions, asset management, maintenance and spares planning, budgeting and project feasibility studies. Typical users include dependability/reliability engineers, systems and design engineers, maintenance and asset managers, procurement officers, project managers and financial analysts performing total cost of ownership and business‑case analyses.

FAQ

Q: What is this standard?

A: An application guide (IEC/EN 60300‑3‑3:2017) that explains life cycle costing methods and how dependability attributes influence total life‑cycle costs, to support value‑based decision making for systems and products.

Q: What does it cover?

A: It covers LCC concepts and objectives, a step‑by‑step analysis process, cost breakdown structures, dependability‑related cost factors, financial evaluation techniques (DCF, IRR, etc.), cost‑estimation methods, treatment of intangibles and uncertainty, plus illustrative examples and modelling guidance.

Q: Who typically uses it?

A: Reliability and maintainability engineers, systems engineers, asset and maintenance managers, procurement and project managers, and financial analysts involved in total cost of ownership and investment decision work.

Q: Is it current or superseded?

A: Edition 3.0 (2017) cancels and replaces the 2004 edition. As of 24 February 2026 the 2017 edition is the current IEC/EN text (IEC lists a stability date through 2027), and national EN/UNE adoptions are active; check the IEC/CENELEC/UNE catalogues or national body for amendments or later editions.

Q: Is it part of a series?

A: Yes — it is one application part of the IEC/EN 60300 dependability management series (part 1 general principles and other application guides in the 3‑x family covering analysis techniques, data collection, supportability, maintenance and logistics).

Q: What are the key keywords?

A: Life cycle costing (LCC), total cost of ownership, dependability, reliability, maintainability, availability, cost breakdown structure, discounted cash flow, sensitivity analysis.
