Product planning / production

Product planningChain store-Co-opBy retailers such asGSC-Full eclipse chain-Eight societyBy a joint purchasing organization by multiple chain stores, such asKokubu-Mitsubishi foodIt is roughly divided into three types by major wholesalers such as.

For the production and supply of products, when ordering and supplying from small and medium-sized manufacturers, when ordering and supplying from a manufacturer specializing in contract manufacturing, ordering from a major manufacturer with a national brand and ordering existing national brand productsOEMThere are cases where it is supplied (controlled label) and cases where it is produced and supplied in-house (chain brand).

Manufacturer

Until the 1980s, it was often outsourced to small and medium-sized manufacturers with weak brand power.品質It was one of the causes of inferiority, but in recent years, it is often planned and produced jointly with major distribution groups and major national brand manufacturers.[Source required]..As a result, quality has become stable, leading to a PB product boom from the mid-2000s.[Source required].

Except for some companies, the seller (retail store) handles various inquiries about products, so the manufacturer (manufacturer) is not open to the public in principle.[Note 3][Source required]..However, it will be listed if the product (alcoholic beverages, dairy products, etc.) that the manufacturer is required to list by law or if it is published under the private brand policy.[Note 4][Source required]..In particular, the contents may be the same as those of major national brand products, or the product may be aimed at increasing the sense of security and bargain for consumers by knowing the manufacturer.[Note 5][Source required]..For foods that can be preservedAfter-Sales ServiceIn some cases, the manufacturer in charge of manufacturing may be the contact point for inquiries.[Source required].

However, it was discovered at the end of December 2013Acry Foods pesticide contamination caseThen, because the collection of the target product without the manufacturer's name was hindered, the coping method when a product requiring collection occurred became apparent as a problem.[2]..Because of that, from April 2015, 4Food Labeling LawWith the enforcement, including national brand productsUse of factory-specific symbols only when manufacturing the same product in multiple factoriesFor products manufactured in only one factory, it is necessary to display the manufacturer's name and the name and address of the manufacturing factory (1 year and 6 months for fresh foods and 5 years for processed foods).[3].

Merit

  • Consumer side
    • You can buy products of almost the same quality as national brands at a lower price.
    • You can purchase high quality and value-added products that are not found in national brands.
  • Sales side
    • Since the product specifications can be easily changed, it is possible to sell products that directly reflect the voices of retailers and consumers.
    • Since no advertising / operating costs or wholesalers are required, the gross profit margin is about 5 to 10 points higher than that of national brand products.[1], The selling price can be set freely (≒ ""EDLP)).
    • By specifying raw materials, manufacturing methods, and specifications, it is possible to add original value to products and improve the corporate and brand image.
  • Manufacturer side
    • By guaranteeing a certain amount of sales, it is possible to increase the factory utilization rate and efficiently produce even in the off-season, which makes it possible to reduce costs.
    • By stabilizing sales, the management of the manufacturer will be stable.
    • It can create the soil for national brand development and marketing.

Demerit

  • Consumer side
    • Even if it looks the same as a national brand, the raw materials, blending ratio, processing method, and content may be changed, which may affect the flavor and texture, and the quality may be appropriate for the price or higher.
    • Since retailers give priority to private brand products, the handling of national brand products may be reduced and the range of product choices may be narrowed.
    • Since there are many products with lower prices than national brands from the beginning, it is difficult to become a bargain product (Expiration SoonExcludes discounts on nearby foods).
    • Since most products do not list the manufacturer, it is difficult for consumers to directly convey their opinions to the manufacturer.
  • Sales side
    • Since it is a full purchase, it cannot be returned even if it is unsold, and it cannot be resold to other companies.In addition, if the timing of additional production is incorrect, the product will be out of stock for a long period of time, so inventory risk always occurs.
    • In the event of an accident such as food poisoning or foreign matter contamination, the manufacturer must take responsibility for handling complaints on behalf of the manufacturer.Also after the end of productionAfter-Sales ServiceMust also be done.
  • Manufacturer side
    • Sales of national brand products produced in parallel may decrease.
    • Depending on the product, the gross profit margin may be about 10 points lower than that of national brands.[1].
    • If there is a discrepancy with the standard pointed out by the seller, you may be refused receipt of the product.Especially in the case of food, it is not possible to refill the contents, let alone resell it, and it is necessary to hold a large amount of inventory or dispose of it as it is, and the cost that should be recoverable does not come in, which makes it difficult to raise funds.
    • If the dependence on contract production increases, the development and sales capabilities of national brands will decline, and the factory utilization rate will depend on the order quantity of the ordering party.

Search engine issues and problems

Challenges of multilingualization

The so-called "ratio of the Internet population in terms of the language used" isInternet ArchiveUsingEuro MarketingとGlobal ReachSince the past monthly materials have been organized, the following trends are being followed.

1995 According to the previous Internet Society, English accounted for 85% of the languages ​​used on the Internet.ITAs shown in the table above, due to the progress of2000 At the end of the year, the English and non-English language populations reversed, and that trend continues.

As of February 2005, 2, Google, which is a representative WWW search engine, has registered over 2 billion 80 web pages. Search engine users tend to assume that they can easily get the information they want from over 8,058,044,651 billion web pages, but for example, it is not easy to search Japanese sites using terminals such as computers that cannot input Japanese.

Search engine danger

While search engines are convenient, there are also references and materials regarding the dangers and damage examples. Regarding the research report on the safety of search engines, McAfee, a security vendor that provides anti-virus software, announced on June 2007, 6, "Survey reports on the safety of search engines," saying "Search engines are dangerous. Yes, if you enter a keyword into a search engine and check the risk of sites that appear in the top, sites displayed as advertisements are 4 times as dangerous as sites that are not.”[12][13].

Also, according to a research report released on May 2006, 05, search engine keyword search results have dangerous links, so don't assume that search engines will protect you. On the contrary, search result rankings often don't reflect the safety of the site, and warn users that they are at high risk, especially when visiting search engine ads.[14].. In addition, in a survey report on the risk of search engine sites, McAfee announced the "Search Engine Safety Survey" and stated that "the most dangerous results are in Yahoo."[15].
