In contrast to tqm, what approach seeks radical change through innovation?

As for me, in contrast to tqm, the sphere which approaches radical change through innovation is reengineering. I think that this answer is suitable as reengineering is a process which changes format of the corporations by inventing and developing business plan/design of company that widen the range of features.

Explanation:

The Vijayanagara Empire (also called Karnata Empire, and the Kingdom of Bisnegar by the Portuguese) was based in the Deccan Plateau region in South India. It was established in 1336 by the brothers Harihara I and Bukka Raya I of the Sangama dynasty,members of a pastoralist cowherd community that claimed Yadava lineage. The empire rose to prominence as a culmination of attempts by the southern powers to ward off Islamic invasions by the end of the 13th century. At its peak it had subjugated almost all of South India's ruling families and the Sultans of the Deccan region, thus becoming a notable power. It lasted until 1646, although its power declined after a major military defeat in the Battle of Talikota in 1565 by the combined armies of the Deccan sultanates. The empire is named after its capital city of Vijayanagara, whose ruins surround present day Hampi, now a World Heritage Site in Karnataka, India.The writings of medieval European travelers such as Domingo Paes, Fernão Nunes, and Niccolò Da Conti, and the literature in local languages provide crucial information about its history. Archaeological excavations at Vijayanagara have revealed the empire's power and wealth.

The empire's legacy includes many monuments spread over South India, the best known of which is the group at Hampi. Different temple building traditions in South and Central India came together in the Vijayanagara Architecture style. This synthesis inspired architectural innovation in Hindu temples' construction. Efficient administration and vigorous overseas trade brought new technologies such as water management systems for irrigation. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit, while Carnatic music evolved into its current form. The Vijayanagara Empire created an epoch in the history of Southern India that transcended regionalism by promoting Hinduism as a unifying factor.
