Dr. Nitin Paranjape (Doc) completed his post-graduation in medicine – obstetrics and gynecology (he did complete it!) – in Mumbai, India. Technology was his hobby. Initially, he developed many medical applications, first on the Sinclair Spectrum and then on PCs. Soon he expanded to corporate IT. His organization (Mediline) was one of the earliest partners of Microsoft in India. For 15 years, he was considered to be the pioneer of the entire Microsoft platform, cutting across programming tools, databases, infrastructure, and Office. However, he noticed that most of the technologies were largely underutilized – due to which people were still inefficient. Therefore, he changed his focus to the most commonly used (and most underused) tool in the world – Microsoft Office. Now, he is known as the Productivity Guru and Dr. Productivity. He has coached over 400,000 professionals across 3,000+ customers in 18 countries. He even coaches Microsoft’s own staff and partners about the effective utilization of the Microsoft 365 platform. Having authored 700+ articles in print and 1,000+ blogs, he is a prolific writer, a sought-after orator, and an accomplished speaker. He uses a simple, down-to-earth, humorous storytelling style enhanced with live demos to educate and empower his audience. Customers call his sessions a “magic show!”. He is also a PROSCI-certified change management consultant. Doc’s passion is to improve the efficiency of every user of the Office platform. This book is the distillation of his knowledge and experience gained over 30 years of work.
