Leadership qualities
On Creativity
Dr Kalam has always emphasized on the importance of creativity and innovation in anything we do. He says that India needs creative leaders rather than managers or commanders.

With His vision he developed The concept of PURA -- which stands for "Providing Urban amenities in Rural Areas".it is about giving a cluster of villages physical, electronic and knowledge connectivity. he believed that connectivity is the key to bridging the rural-urban divide. This will lead to development of villages of india.

On Integrity and Transparency
Everything a leader does should be transparent and high on integrity. For example: during his term of presidentship he returned the Office of Profit Bill to the Parliament. The reason was that he felt there was no transparent system for determining whether a post was an office of profit. That was a major decision. He studied the bill and returned it to the parliament for reconsideration. It created its own dynamic and many criticised him bt he did wht he felt ws right.

Dr Kalam has a very idealistic view on success and failure. the leader must know how to manage success, and even more importantly, failure. He says that when failure occurs, a leader should humbly own it and acknowledge it. When success comes, the leader should give credit to all the people who worked for it.
. In 1973 he became the project director of India's satellite launch vehicle program, commonly called the SLV-3. Their goal was to put India's "Rohini" satellite into orbit but due to some last moments technical problems the whole rocket system plunged into the Bay of Bengal. It was a big failure. And the chairman took took responsibility for the failure bt it would have been a success the credit would be given to whole team. Kalam says That this is the most important trait a leader should posses.
