This study analyzes corporate entrepreneurship as a driver of service innovation at UAB Šiaulių Bankas, assessing the impact of leadership, organizational culture and participation of employees on respective decisions. Here we use a mixed methods approach, including expert interviews and surveys from 100 employees. The results show that 75% of respondents think leadership is “significant” or “very significant” to achieving innovation, with effective leadership encouraging risk taking, collaboration, and a shared vision. Employee involvement was found to be a key driver, with 65% of people rating management effectiveness as "effective" or "very effective" and 40% saying that revenue growth was the most important metric to evaluate innovation success. The results also reinforce the notion that external influences in the shape of regulatory guidelines, market trends serve both as an enabler and impediment to the process of inducing innovation. Besides this, if employee perspectives and practical knowledge are seen as essential for speeding up the innovation process, 70% of interviewees stated that they are "often" or "very often" involved in the innovation process. These successes also come coupled with challenges, as infrequent strategy reviews, 40% of them take place on an annual basis, could hinder their agility in today’s fast-paced, ever-changing market. The researchers assert that cultivating ingenuity with the embracement of ingenuity at leadership level, increased review cycles, and harnessing employee inputs could assist in sustaining innovation. Such knowledge serves as a basis for how UAB Šiaulių Bankas can remain competitive and deliver outstanding service using corporate entrepreneurship.
