A process improvement sampling methodology, known as process variation diagnostic tool (PROVADT), was proposed by Cox et al. (2013). The method was designed to support the objectivity of Six Sigma projects performing the measure-analyse phases of the define-measure-analyse-improve-control cycle. An issue in PROVADT is that it is unable to distinguish between measurement and product variation in the presence of a poor Gage repeatability and reproducibility (R&R) result. The purpose of this paper is to improve and address PROVADT’s sampling structure by enabling a true Gage R&R as part of its design.

This paper derives an enhanced PROVADT method by examining the theoretical sampling constraints required to perform a Gage R&R study. The original PROVADT method is then extended to fulfil these requirements. To test this enhanced approach, it was applied first to a simulated manufacturing process and then in two industry case studies.

The results in this paper demonstrates that enhanced PROVADT was able to achieve a full Gage R&R result. This required 20 additional measurements when compared to the original method, but saved up to ten additional products and 20 additional measurements being taken in future experiments if the original method failed to obtain a valid Gage R&R. These benefits were highlighted in simulation and industry case studies.

The work into the PROVADT method aims to improve the objectivity of early Six Sigma analyses of quality issues, which has documented issues.

By the beginning of the war, Germany's over‐all self‐sufficiency in food had reached a level of approximately 83 per cent., on the peace‐time basis of 2,200—2,400 calories per person per day. In respect to some types of food, however, the situation was not satisfactory. For example, before the war she produced approximately 73 per cent. of fish requirements, 12 per cent. of corn, 50 per cent. of legumes, and 60 per cent. of fat within her own boundaries. The country could be fed at a reduced level by the produce raised within its own boundaries if food were perfectly controlled and evenly distributed. However, in practice, individual provinces were much less favourably situated in this respect. Western Germany, an area of relatively small and diversified farms, was critically dependent on the eastern provinces for its flour, grain, and potato supplies. It is clear that all German civilians could be fed at a uniform level of adequacy during a war only by control of the country's food supply at the national level and by the continued operation of the new transportation network of the country. For this reason the bombing of rail and inland water transportation facilities became such a serious threat to national uniformity in food distribution. Of the many kinds of centralised food processing industries known in the United States, only a few played an important role in the food supply of German civilians. The principal examples of these were grain milling, sugar production and refining, and the large bakeries of urban areas. The damage or destruction of these facilities, incidental to air attack on other industrial targets, seriously decreased their production capacity. Bombing destroyed the mills for processing 9 per cent. of the German rye output and 35 per cent. of the wheat output. Of the sugar refineries four plants producing 300,000 tons annually, were destroyed. This represents a 38 per cent. decrease in production of sugar. Similarly bombing of chemical plants was largely responsible for the decrease in the supply for fertiliser nitrogen. In 1939, 718,000 tons of fertiliser nitrogen were available, but by 1945 this had decreased to 140,000 tons. The significance of this destruction of facilities vital to the feeding of a country already on a border‐line diet is ominous. Reliable estimates indicate that aerial bombings destroyed 35 per cent. of Germany's total (approximately 460,000 square metres) cold storage capacity. The increased use of cold storage intensified their dependence on transportation and on the continuity of the power supply. Aerial attack, as a result, not only decreased usable cold storage space, but also seriously interfered with the operation of the remaining space by impeding shipments and interrupting sources of power. It was the constantly reiterated opinion of all food officials that the bomb destruction of the transportation network was the largest single factor contributing to the disruption of the food supply. Bulk shipments which had been carried on inland waterways were seriously impeded by the bombing of canals. Aerial attack against railway lines, bridges and terminal facilities caused widespread interruptions in service and destroyed rolling stock, freight en route and handling facilities at terminals. It is not possible at this time to state exactly in what measure the curtailment of the national diet contributed to the ultimate defeat of Germany. The evidence available indicates, however, that it was an important factor. There is in any case no doubt that strategic bombing is the major element contributing to the present shortage of food in Germany. It was not apparent that the Germans considered the vitamin and mineral content of food in determining the ration allowances of the people. Immediately with the beginning of the war, all the principal foods were rationed, so that the lack of recognition of the importance of the vitamin and mineral content of this ration actually was an additional point of vulnerability for the German diet. With a food economy so vulnerable it is not surprising to have found that the basic food rationing programme was abandoned early in 1945 when the destruction of transport and communications by the strategic air offensive attained major proportions. This necessitated falling back on the inadequate system of regional self‐supply. The destruction of large food stocks, processing plants and cold storage plants by bombing also contributed to the general deterioration of the German food supply. There is ample evidence for the conclusion that as a result of the strategic air offensive the nutritional demands for the continued health of the German people could not be met.

The purpose of this paper is to examine the efficiency and objectivity of current Six Sigma practices when at the measure/analyse phase of the DMAIC quality improvement cycle.

A new method, named process variation diagnostic tool (PROVADT), demonstrates how tools from other quality disciplines can be used within the Six Sigma framework to strengthen the overall approach by means of improved objectivity and efficient selection of samples.

From a structured sample of 20 products, PROVADT was able to apply a Gage R&R and provisional process capability study fulfilling the pre-requisites of the measure and early analyse phases of the DMAIC quality improvement cycle. From the same sample, Shainin multi-vari and isoplot studies were conducted in order to further the analysis without the need of additional samples.

The method was tested in three different industrial situations. In all cases PROVADT's effectiveness was shown at driving forward a quality initiative with a relatively small number of samples. Particularly in the third case, it lead to the resolution of a long standing complex quality problem without the need for active experimentation on the process.

This work demonstrates the need to provide industry with new statistical tools which are practical and give users efficient insight into potential causes of a process problem. PROVADT makes use of data needed by quality standards and Six Sigma initiatives to fulfil their requirements but structures data collection in a novel way to gain more information.

The purpose of this paper is to explore the configurations of supply chain integration.

The authors use qualitative data from manufacturers shortlisted for the UK’s Manufacturing Excellence awards over three years. Detailed processes and policies of 68 manufacturers are analysed.

Process structure and product newness require different supply chain configurations, which change as products mature. Supply chain integration is dynamic, and the extent of collaboration between suppliers and customers will be different at different moments in time. The authors define and discuss four key supply chain configurations: customised; ramp-up; recurring; coordinated.

Future studies on supply chain integration should be controlled for the variation in the configurations. A limitation is the use of data which were derived for an award. The paper explains how the authors have mitigated the associated risks.

The configuration of integration will change as the manufacturing plant becomes more familiar with a product. Additionally, different suppliers may provide better support at different stages of a product’s lifecycle. To yield better performance, supply chain integration would need to take different forms. Efforts to integrate with suppliers should not be avoided as, when certain conditions are met, integration can lead to improved performance.

The authors have identified manufacturers’ main process structures and products’ newness as two strategic characteristics that differentiate integration approaches with customers and suppliers, and defined four integration configurations. To the authors’ knowledge this is the first study to argue that these also define the configuration of supply chain integration.

The British countryman is a well‐known figure; his rugged, obstinate nature, unyielding and tough; his part in the development of the nation, its history, not confined to the valley meadows and pastures and uplands, but nobly played in battles and campaigns of long ago. His “better half”—a term as true of yeoman stock as of any other—is less well known. She is as important a part of country life as her spouse; in some fields, her contribution has been even greater. He may grow the food, but she is the provider of meals, dishes, specialties, the innovating genius to whom most if not all British food products, mostly with regional names and now well‐placed in the advertising armentarium of massive food manufacturers, are due. A few of them are centuries old. Nor does she lack the business acumen of her man; hens, ducks, geese, their eggs, cut flowers, the produce of the kitchen garden, she may do a brisk trade in these at the gate or back door. The recent astronomical price of potatoes brought her a handsome bonus. If the basic needs of the French national dietary are due to the genius of the chef de cuisine, much of the British diet is due to that of the countrywoman.

A representation in relation to a sale—written or in advertisements, films or labels or in the spoken word—may be (a) a mere expression of opinion or commendation by a seller of his wares; or (b) it may constitute part of the description of the thing sold; or (c) consist of a warranty. The law allows a certain latitude in the efforts to gain a purchaser; does not insist on the absolute truth of the commendatory expressions habitually used to induce people to buy. The flourishing expressions used by auctioneers and estate agents—“ this superlatively appointed residence ”—are commonplace examples of this recognised “puffing” of wares. “ Puffing ” in relation to sale is merely an extension of the everyday usage of accepting half‐truths, untruths or the conventional evasion of truth; even as part of the bedside manner, the splendide mendax, of the doctor! What constitutes the upper limit of permissible misrepresentations such as these is by no means clear, either in civil law or in the growing body of statutory law regulating trade descriptions and advertisements of recent years, for here, as with so much law relating to sale, there is that same cleavage between civil rights of action and prosecutions to inflict penalties for statutory offences.

A highly significant action taken by the Minister of Agriculture, Fisheries and Food, reported elsewhere in this issue, could well result in important advances in surveillance and probably legislative control over enforcement of certain aspects of EEC legislation in the Member‐states. The Minister has sent an urgent request to the Commission in Brussels to dispatch inspectors to each country, including the United Kingdom, to examine and report on the standards of inspection and hygiene with detailed information on how the EEC Directive on Poultry Meat is being implemented. Information of the method of financing the cost of poultrymeat inspection in each country has ben requested. The comprehensive survey is seen as a common approach in this one field. The Minister requested that the results of the inspectors' reports should be available to him and other Member‐states.
