Concept that time is a resource and a firm thatmake better use of time (in responding to thechanging market situations and otherenvironmental conditions) acquires a
competitive advantage.
Time-based competition is the extension of JITinto every facet of the product delivery cycle,from research and development throughmarketing and distribution of the final product.
The term was coined by the US consultant George Stalk, Jr., of BostonConsulting Group and popularized by his book 'Competing Against Time.

Time based competition through productdevelopment time reduction
3M reduced its new product developmenttime from two years to two months
Fuji Xerox (Japan) reduced its photocopierdevelopment time from four to two years
Toyota achieved a new productdevelopment time two years shorter thanthat of the Big Three automakers
Cincinnati Milacron met the onslaught offoreign competition in the injectionmoulding machine business by developinga better performing, lower cost machine innine months as compared to its historicalaverage of two years
Time based competition throughmanufacturing lead time reduction
Motorola's cellular phone was drasticallycut from several weeks to four hours.
Toyota takes two days to produce a car,which is three days shorter than NorthAmerican manufacturers.
Manufacturing lead time for Allen-Bradley's World contactors and relays is asingle day.
Johnson and Johnson's Vistakon divisionhas the top selling contact lens in themarket largely due to its rapid (three daysor less) and reliable (99.99 per cent on-time) delivery of disposable contacts tocustomers.

Shortening of product life cycle to 2-3 years in afew years time
Large number of design changes during the
design phase (6,000 changes on average for a newautomotive body development)
Long ramp up time
Low production yield
The old assembly line cannot be entirely used for anew product

In the last decade, the so-called stream of variation analysis (SOVA) methodologyhas been proposed and developed to overcome the aforementioned challenges.
SOVA is a generic math model for variation propagation analysis in multistagemanufacturing systems.
SOVA integrates multivariate statistics, control theory as well asdesign/manufacturing knowledge (CAD/CAM models) into a unified framework.
The stream of variation analysis (SOVA or SoV) methodology is a genericsimulation engine for modelling, analysis, and performance prediction ofmultistage manufacturing processes
Important in industries where product geometry and dimensional variation are ofcritical importance

SOVA serves two objectives
In the design phase, the SOVA can be used for analysis, prediction, andoptimization of manufacturing system performance following theconcept of FTRDesign.
Given the process and tooling design information, SOVA can simulatethe variation propagating throughout the process and then predict thefinal product-dimensional variation and resultant product geometry.
In the production ramp-up phase, SOVA can be used to identify and isolatefault rootcauses following the concept of FTRDiagnosis. SOVA candemonstrate high responsiveness in identifying and isolating root causesof dimensional variation
