When starting something new and hoping to complete it successfully, project management can be a powerful aid. Project management provides a systematic approach by defining a new undertaking as a project and explaining how it should be managed from initiation to completion. This book is especially helpful when the new undertaking involves software development, as software projects have a high risk of failure and are particularly difficult to manage. Developing software and using it to create new business opportunities is highly attractive. Above all, it often requires relatively low initial investment and carries comparatively lower risk. We have seen numerous successful cases in countries such as the United States and Korea, where entirely new businesses—previously nonexistent—were implemented through software and delivered as applications. Generating ideas for new businesses is especially exciting for students and young people, and it offers the possibility of achieving “great success at a young age.” This book introduces project management techniques and knowledge for those who wish to implement their ideas through software. Learning these in advance helps save time and effort, overcome various risks, and significantly increase the chances of success. Based on years of experience working in coding, system analysis and design, as well as serving as a project manager and quality professional, the author has witnessed many cases in which software development projects were less successful than expected or even failed entirely. Project failures sometimes escalate into legal disputes and cause significant hardship for many project participants and stakeholders. Those who wish to design innovative businesses, develop software, and rapidly acquire customers through successful deployment must first possess strong planning and execution capabilities. Such planning and execution must “make sense” from the very initial concept. In simple terms, “making sense” means answering the fundamental question: “Is this truly a viable business?” Business plans and execution strategies must be documented, and projects based on these plans must be persuasive to stakeholders who participate in the venture. Through project management, readers can expect to turn these ideas into reality. By following the processes explained in this book, readers will gain hands-on knowledge and techniques they may not have previously known, avoid unnecessary trial and error, and ultimately improve their chances of success.
