In an era when physical tail space is still at a premium, constrained by planning restrictions and rising costs, productive use of space is a key indicator of buying and merchandising success, and high space productivity depends on offering the right range, in a logical layout, with products available and easy for the customer to find. Decisions about how much space to devote to each product line and its location in the store play an important role in the pursuit of merchandising success.
Space selling constraint applies to all retailers, but in non-store retailing the constraints are different. A mail order retailer, for example, has page space and the number of pages in a publication as constraining factors, whilst a TV shopping channel needs to break down the airtime to different products. However, internet retailing offers great opportunities for adding space without much additional resource input. The main constraint on the amount of space used in a virtual outlet is the customer’s attention span. In spite of this additional freedom, the objectives of space allocation are essentially the same no matter which retail format is used.
The management of retail space is concerned with a number of key objectives. The first is to optimize both short-term and long term returns on the investment cost of retail pace. The second is to provide a logical, convenient and inspiring interface between the product range and the customer. This can be particularly important in a large store, where customers can quite easily become overwhelmed and lost. Another objective is to make sure that the right selection of products is available; that products fit into the retail space and that stock-outs are avoided. Choice for the customer is maximized when the best selection for them is put into the available space. Space allocation aim has an important role to play in communicating the retail brand, helps a chain of retail outlets to achieve visual consistency, so that customers arc reassured by the similarity of the store layout and shelf appearance.
The Space Management Process
A retailer goes through a number of stages when allocating space to products. These stages are discussed below.
Measuring Space Selling
Although space in a store outlet is three dimensional, retail space is often measured in square, rather than cubic units, Square units arc appropriate where, for example in fashion retailing, a variety of single tier fixtures stand on the shop floor. Many fixtures, however, arc multilevel and so more appropriate ways of measuring space to allocate might be on the basis of linear or cubic footage. Measurements of space that are more specific to individual retailers might be useful, such as the number of pages to be published in a catalogue or the total number of fixtures available in an outlet.
Space Productivity
The two principal measures of retail success arc sales and profits. Sales volume and profitability can also he measured in relation to the amount of space used to generate those levels of sales and profits. This can then be compared with the level of financial investment in that space. The resulting measures express the productivity of retail space. Sales (or profits) per square meter is a commonly used measure of retail space productivity, which is an important concept in the evaluation of retail product management performance.
Dividing the space into selling areas
At this stage, space management is concerned with allocating space to different product areas, defined according to individual retail businesses, but usually on the basis of product (department or category. The amount of space will he determined to a greater extent on previous performance indicators, typically sales values. However, sonic products, because of their physical characteristics may need disproportionate amounts of space in relation to sales. In a department store, home furnishings may need a relatively large amount of space to generate a good level of sales because the products are bulky, a large variety of merchandise is needed for customers to choose from and a lot of display space is needed to do the product justice. On the other hand, jewellery is a high value product category that needs relatively small amounts of space for display and selling purposes. The stage a product category is at in its life cycle is likely to influence the space allocation at this level. If a category is growing, then more space should be allocated, whereas a declining category needs to have its space rationalizes.
Typical ‘hotspots’ In a Space selling
Particularly evident in department stores, where specialist products such as furniture and home entertainment, as well as hairdressing salons and customer service department’s located on basement or upper floors, Customer flow can also be encouraged by locating high demand items throughout the store layout, with plenty of impulse items located in between. Retailers need to find a balance between maximizing sales of high demand products, generating flow around slower selling products (which may have higher profit margins), and providing logic and convenience in the layout for the customer.
Product adjacencies
A logical route through the different product categories or departments is part of a customer focused offer, and can encourage linked sales. For example, in a baby equipment retailer like Mother cares it makes sense for merchandise to be grouped into themes for space planning purposes. These product themes are then presented in a logical way to the customer as they move through the store. Products for immediate needs, such as feeding and general baby care come first, followed by bath time and clothes; and then on to the more expensive, one purchases in the travel and nursery departments.
The barbecue season provides a good opportunity for retailers to generate interest and sell distinctive groups of complementary products. Some of these products are strictly seasonal: the barbecues themselves and the briquettes for example. However, other products can be given additional space allocations in the seasonal aisle as part of the ‘barbecue category’. Firelighters, matches, marinades, sauces, disposable tableware and beer are products that are found around the supermarket throughout the year, but are given a boost In the barbecue season by being merchandised as complementary goods.
It is estimated that guests take an average equivalent of eight drinks when they are Invited to a barbecue, and studies (bulk packed small bottles of beer) are particularly popular for barbecues as they are easy to handle, ‘women friendly’, and easily chilled. Whilst the majority of barbecue beer is bulk purchased In advance from supermarkets, and then chilled down at home, convenience store retailers are often used for guests to buy drinks en route, and so providing chilled beer becomes important for this type of retail format.
Allocation space to individual product
Having made a plan for the layout of departments or categories within the retail outlet, the next stage is to make a decision about exactly how individual product lines should be displayed within the outlet, whether the product is going to sit on a fixture, or be represented by a photograph within a page spread. Various approaches to space allocation are discussed, for example by using sales or profits as a guideline, some practical challenges arc considered, and the relationship between category management and space allocation is explored in this section.
Allocating space on the basis of sale
The guiding principle here is the more a product sells, the more space it should be given. Retaining a high stock service level will depend on retailers ensuring that they devote enough space to a high demand product, such as milk, to prevent replenishment of that item becoming inefficient and inconvenient to the customer. A fast selling item however may not be one that a retailer makes much profit on (again milk is a good example), and so they may decide to allocate more space to their profitable lines. In taking this approach, however, the retailer is likely to encounter the problem of not devoting enough space to fast moving lines, so a balance has to be achieved. Another decision that has to be made is which €˜sales’ figure should he used for the allocation exercise, Alternatives are historical sales figures (for that outlet); market share figures; or projected sales figures.
Store A is a branch of clothing retailer XYZ in a medium sized town centre. Ten miles away there Is a regional shopping centre where branch B Is located and twelve miles In the opposite direction, branch store C Is located In the heart of a city centre shopping complex. The policy of retailer XYZ is to offer a returns policy In all of its stores for products bought in any outlet nationwide (including those purchased from its web site). Shoppers from the town where store A is located, often take shopping trips to the neighboring centres, where B and C are located, especially if they are wanting to make a major purchase such as a coat or a suit, and require a wide choice of retail stores to select from. Unfortunately for store A, any unwanted products usually end up being returned to the customer’s local store. This has the effect of distorting the sales figures for store A, upon which space allocation decisions are made. Unfortunately, the retailer’s information system does not recognize the difference between a returned garment from the original store and one returned from a different outlet. In order to counteract this problem, which can be quite widespread, a retailer would need to allocate space on the basis of estimated sales rather than historical sales.
Space elasticity
Allocating space according to a measure of sales assumes that there a relationship between the amount of space and the rate of sales, this relationship is termed the space elasticity of a product and it refers to the extent to which the sales of a product will change in response to a changed. In the amount of space allocated to that product Research suggests that space elasticity not uniform amongst products, or across stores or departmental locations.
Using profit measures as a basis for space allocation ill prevent a business manager from allocating large amounts of best quality retail space to unprofitable products. They could mean, however, that a retailer was allocating unnecessarily large amounts of space to products that would sell as well with a smaller space. Profitable lines may not in fact sell very quickly at all, and allocating extra facings or shelves of the product may have very little impact on the sales of the product. In this case the quality of the space becomes important, so the retailer can locate high profit items in locations around the stare that arc better selling. The relationship between the sales and generated by different products, and suggests how space and ranging decisions should be made accordingly. Allocating space according to sales, and in particular, product profitability, is working with the interests of the retailer, and not the customer in mind and therefore may suggest an illogical and presentation of products. Long term profitability depends on customer loyalty, which is dependent (among many other things) upon being satisfied with the presentation and assortment of products. Fine tuning the allocation of space within a retail outlet therefore requires extensive amounts of high quality data, together with a pragmatic and customer orientated managerial approach at store level.
Productivity and efficiency and towards are visual display improvements. Once an optimum level of efficiency is achieved, space planners can move onto the objective of making their products and fixtures more attractive than their competitors. Some of the latest planning systems are able to simulate the entire store environment, so that the product manager can view an attractive plan in virtual reality and make any adjustments they fed are necessary. Recent space optimization technology applications offer the opportunity to create specific platform.
Space Allocation and Category Management
Although the performance of individual product lines is Important to retailers in terms of the rate of sales which influences availability and the levels of contribution to turnover and profitability, the focus of performance In many’ retail organizations is at product category, rather than individual SKU level. A retailer is more interested in overall levels of sales and profits generated by their product range, rather than the sales of a single line that might be of interest to its manufacturer. The product category has emerged as a manageable classification for most aspects of product management, and certainly applies in the case of space management. In fact, many would argue that space planning and allocation and the systems that drive the process can only be properly implemented in tandem with a category management approach.
Category management seeks to optimize the depth and variety of a product assortment within a specified amount of retail space and to generate maximum profitability by seeking efficiency in the operations that support the depth and variety. This includes replenishing to guarantee availability’ and adding new products and running promotions to generate customer interest and increase short term sales of particular products, without harming the overall profitability of the category. Space allocation systems allow (Inc tuning of a category assortment, provide the means by which product and category performance can be monitored and analyzed. and by using the programme output the plans can he easily communicated and successfully implemented within the various retail out lets. In some categories key brands are dominant, in which case their presence needs to have immediate impact within the space allocation plan. Other categories are very competitive, in which case low price, budget own brand and promotional products strongly on the promotional. Many businesses use the principle that shoppers will a category from bottom to top, and left to right, and so well-known brands arc placed on middle and lower shelves on the left of the category space in order to provide strong cues to the customer. Premium products meanwhile are placed on high level shelves, selecting their high quality positioning, and the fact that the customer for premium products will seek out the better quality product within the category. In some categories the customer decision-making processes are quite unique and nerd to he fully reflected within space allocation plans. For example, the decision sequence for wine is generally as follows:
Colour —— Country of origin ——– Price Level ——- Brand
Whereas the decision sequence for yoghurt might be:
Natural or flavored ——— type (low fat, standard or luxury) —- Price Level —– Brand Name
These decision processes should determine how products arc displayed within the category space.
In certain modes, if the product is maintained in the offer, long-term customer satisfaction will be retained In spite of the Individual poor product performance. Therefore it is the store’s personality traits that determine the core product ranges, and not the size; the size of the outlet determines the width and depth of the selling type that would appeal to the local customers, Stores are empowered with the merchandise that allows them to drive local market opportunities and local suppliers can also be involved in the process of providing tailored products for individual store needs, As retailers offer more formats from which customers may choose to shop, format preferences and product preferences can be matched, For example, Tesco found that its online shoppers tended to from more affluent backgrounds, and so the on-line product offer is tailored accordingly, with a large range of wines and few value lines,
For many small retailers the cost of a computerized space planning is prohibitive, and so many rely on basic sales and profit margin analysis combined with trial and error in space allocation decision making.
