Deming-14 points for management

(create constancy of purpose, adopt a new philosophy, cease dependence on inspection to achieve quality, end the practice of awarding business on the basis of price tag alone, improve constantly and forever every process for planning-production-and service, institute training on the job, drive out fear, breakdown barriers between and within departments, eliminate slogans, eliminate numerical quotas, remove the barriers that rob people of the right to pride of workmanship, institute a vigorous program of self improvement, transformation is every ones job)

Juran-10 steps to quality improvement

(identify customers, discover customers' needs, translate those needs into language, establish units of measure, establish measurements, develop a plan that can respond to those needs, optimize product design to meet our needs as well as customers' needs, optimize product design to meet our needs as well as customers' needs, develop process which is able to produce the product, optimize: prove process capability, transfer to operations)
