Statistical quality control of information

This paper was written to promote interest by management and statistical quality control personnel in the current need for statistical quality control of information of all types. By way of illustration, a step by step procedure for implementing such control on computer files is presented. Emphasis has been placed on the sequencing of the system rather than the underlying techniques.

‘Winston has gone mad’: Churchill,the British Admiralty,and the Rise of Japanese Naval Power

As Chancellor of the Exchequer during the late 1920s, Winston Churchill was at the center of British strategic decision making about how to respond to the naval challenge posed by Japan's rise as a rival sea power. Churchill downplayed the likelihood of war with Japan. The leadership of the Royal Navy disagreed: they saw Japan as a dangerous threat to the security of the British Empire. Examining this dispute between Churchill and the Admiralty highlights the awkward political, economic, and strategic tradeoffs confronting British leaders between the world wars.     

Troubled triangle: Russia,Ukraine and the United States

A potentially productive triangular arrangement among Russia, Ukraine, and the United States emerged in 1994 from efforts to constrain nuclear weapons diffusion. By 2001, this promising initiative was nearly moribund, owing to the inability or unwillingness of the parties to fulfill the commitments of subsequent agreements. The domestic and external causes of this failure are many and clear. Yet the advantages to each of reengaging in a trilateral relationship are also plain. This means fulfilling their unfinished agenda by learning from past mistakes, adopting realistic premises and goals, and pursuing ‘bottom up’ as well as ‘top down’ strategies.     

The rationalisation of warship building in the United Kingdom, 1945–2000

After the Second World War the Admiralty and shipbuilding industry agreed that the largest possible capacity for warship building should be maintained. This proved impossible as the Royal Navy struggled to evoke a strategy in the nuclear era and the price of increasingly complex vessels rose remorselessly. As the shipbuilding industry wilted in the 1960s in the face of international competition a process of natural selection was followed by increasing political intervention in the industry. Nationalisation in the 1970s aimed to preserve capacity and employment, policy aims which were reversed by privatisation in the 1980s and which, ultimately resulted in an oligopoly in the warship building sector.     

Soldiers,the Frontier and the Politics of Command in British India

The defence of India in general and the North West Frontier in particular was central to strategic debate within the late Victorian army, creating one of the fault lines between rival factions competing for key commands and appointments. After a discussion of the varying strategic options debated within the British and Indian armies, the article examines the impact of Indian defence upon the ‘politics of command’ with particular reference to the appointment of Commanders-in-Chief in India between 1876 and 1892.
