during which the item is expected by its designers to work within its specified parameters; in other words, the life expectancy of the item. It is not always the actual length of time between placement into service of a single item and that item's onset of wearout. </p><p>Another use of the term design life deals with consumer products. Many products employ design life as one factor of their differentiation from competing products and components. A <a href="/wiki/Disposable_camera" title="Disposable camera">disposable camera</a> is designed to withstand a short life, whilst an expensive <a href="/wiki/Single-lens_reflex_camera" title="Single-lens reflex camera">single-lens reflex camera</a> may be expected to have a design life measured in years or decades. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Long_design_lives">Long design lives</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Design_life&action=edit&section=1" title="Edit section: Long design lives"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Some products designed for heavy or demanding use are so well-made that they are retained and used well beyond their design life. Some <a href="/wiki/Public_transport" title="Public transport">public transport</a> <a href="/wiki/Vehicles" class="mw-redirect" title="Vehicles">vehicles</a> come into this category, as do a number of <a href="/wiki/Artificial_satellites" class="mw-redirect" title="Artificial satellites">artificial satellites</a> and <a href="/wiki/Spacecraft" title="Spacecraft">spacecraft</a>. In general, entry-level products—those at the lowest end of the price range fulfilling a certain specification—will tend to have shorter design lives than more expensive products fulfilling the same function, since there are savings to be made in using designs that are cheaper to implement, or, conversely, costs to be passed onto the customer in engineering to provide a safe margin leading to an increased working life. This <a href="/wiki/Economics" title="Economics">economic</a> truism leads to the phenomenon of products designed (or appearing to be designed) to last only so long as their warranty period. </p> <div class="mw-heading mw-heading2"><h2 id="Obsolescence">Obsolescence</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Design_life&action=edit&section=2" title="Edit section: Obsolescence"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Design life is related to but distinct from the concept of <a href="/wiki/Planned_obsolescence" title="Planned obsolescence">planned obsolescence</a>. The latter is the somewhat more nebulous notion that products are designed so as to become <a href="/wiki/Obsolete" class="mw-redirect" title="Obsolete">obsolete</a>—at least in the eyes of the user—before the end of their design life. Two classic examples here are <a href="/wiki/Digital_camera" title="Digital camera">digital cameras</a>, which become genuinely obsolete as a result of the very rapid rate of technological advances,
