“I think I would like to write a case. What do I do now?” The purpose of this paper is to answer this often-asked question by presenting a useful guide for case writers which examines the entire process of case writing beginning with the initial idea and proceeding through required stages leading to the publication of case studies. Further, this guide seeks to emphasize that case writing is a form of research, not just story telling. Ultimately, the increasing interest of scholars in researching, writing, and publishing pedagogical cases provided the impetus for this paper. The four major case writing processes identified in this paper include ideation (idea generation), creation (crafting the case study), application (creating the Instructor’s Manual), and publication (publishing the case). Each of these four processes is presented in detail including examples, pitfalls, and resources. This work is intended to assist novice, as well as experienced, case authors who seek advice on crafting and publishing pedagogical cases in refereed journals. Resources presented in this paper should be helpful especially for aspiring and as yet unpublished case writers.

The paper is based partially on archival research, but most of the content is based on the substantial experience of the authors.

The paper is relevant for upper-level undergraduates as well as graduate students interested in pedagogically based research.

This case discusses Qihoo 360's free business model, how it used this free model to overpower competitors, and how the model evolved over time. Qihoo 360 is a company that took just six years to become a company listed on the New York Stock Exchange (with a market value of over US$ 2 billion). At Qihoo 360's Initial Public Offering (IPO) at the New York Stock Exchange (NYSE), Qihoo's founder Zhou Hongyi reflected on how Qihoo's free business model had brought its current success and speculates on its future challenges.

The authors used both secondary data and field interviews when preparing this case. After reading through various company reports, competitor information, and financial filings, the authors interviewed five top manager team (TMT) members of Qihoo 360, three TMT members of its competitors, and two partners of venture capital investors who have invested in these companies in Beijing or Shenzhen during the last three years. The authors collected 347 media reports related to these companies in Chinese covering seven years of history. This long span of data collection improves the interpretation of the company and helps construct the storyline of the case.

This case is suitable for an MBA course or an advanced undergraduate course in strategic management or a technology-oriented entrepreneurship course, focussing on the topic of the free business model, business model innovation, disruptive innovation, and evolution of the business model during the entrepreneurial process.
