Survey of the adjourned sale rate of the Japanese home video game industry

We carried out a survey of the adjourned sales rate of the Japanese home video games from famitsu, a major weekly magazine, in order to construct a reference index of project management. We chose Playstation®(PS), Playstation2® (PS2) and Game Boy Advance® (GBA®) as the platform and measured the fraction of the titles which were postponed for sale once or more times. The results are as follows: 1) During the first year after the release of the new platform, the rate of adjourned sale was high and gradually declined year by year. 2) In PS® platform, adjourned rate was nearly 50% in the first three years 1994-1996, and declined to 22% in 2001. 3) In PS2® platform, adjourned rate was 33% in the first year 2000, and declined to 26% in 2004, 4) In GBA® platform, adjourned rate was 24% in the first year 2001, and declined rapidly to 7% in 2004. 5) Game titles scheduled to go on sale around the new-year holidays or at the end of the fiscal year showed a significantly higher rate of adjourned sales Author
