Sierra-Cedar built a strong reputation serving diverse sectors such as public sector (government, state, local), higher education, healthcare, and various commercial industries, guiding organizations through complex technological transformations to enhance operational efficiency and achieve strategic objectives. Following its acquisition by The Hackett Group in 2020, its capabilities and expertise have been integrated to strengthen The Hackett Group's offerings in digital transformation and enterprise cloud solutions.
