Explanation

Regression refers to a quantitative measure of the relationship between one or more independent variables and a resulting dependent variable. Regression is of use to professionals in a wide range of fields from science and public service to financial analysis.

To perform a regression analysis, a statistician collects a set of data points, each including a com-plete set of dependent and independent variables. For example, the dependent variable could be a firm’s stock price and the independent variables could be the Standard and Poor’s 500 index and the national unemployment rate, assuming that the stock is not listed in the S&P 500. The sample set could be each of these three data sets for the past 20 years.

On a chart, these data points would appear as scatter plot, a set of points that may or may not appear to be organized along any line. If a linear pattern is apparent, it may be possible to sketch a line of best fit that minimizes the distance of those points from that line. If no organizing axis is visually apparent, regression analysis can generate a line based on the least squares method. This method builds the line which minimizes the squared distance of each point from the line of best fit.

Line of best fit is one of the most important outputs of regression analysis.

Explanation

Overhead variances arise when the actual overhead costs incurred differ from the expected amounts. Managers want to understand the reasons for these differences, and so should consider computing one or more of the overhead variances described below. Each of these variances applies to a different aspect of overhead expenditures. It is not necessary to calculate these variances when a manager cannot influence their outcome.

Fixed Overhead Spending Variance

The fixed overhead spending variance is the difference between the actual fixed overhead expense incurred and the budgeted fixed overhead expense. An unfavorable variance means that actual fixed overhead expenses were greater than anticipated. The formula for this variance is:

Actual fixed overhead - Budgeted fixed overhead = Fixed overhead spending variance

The amount of expense related to fixed overhead should (as the name implies) be relatively fixed, and so the fixed overhead spending variance should not theoretically vary much from the budget.

Fixed Overhead Volume Variance

The fixed overhead volume variance is the difference between the amount of fixed overhead actually applied to produced goods based on production volume, and the amount that was budgeted to be applied to produced goods. For example, a company budgets for the allocation of $25,000 of fixed overhead costs to produced goods at the rate of $50 per unit produced, with the expectation that 500 units will be produced. However, the actual number of units produced is 600, so a total of $30,000 of fixed overhead costs are allocated. This creates a fixed overhead volume variance of $5,000.

Variable Overhead Efficiency Variance

The variable overhead efficiency variance is the difference between the actual and budgeted hours worked, which are then applied to the standard variable overhead rate per hour. The formula is:

Standard overhead rate x (Actual hours - Standard hours)

= Variable overhead efficiency variance

A favorable variance means that the actual hours worked were less than the budgeted hours, resulting in the application of the standard overhead rate across fewer hours, resulting in less expense being incurred. However, a favorable variance does not necessarily mean that a company has incurred less actual overhead, it simply means that there was an improvement in the allocation base what was used to apply overhead.

Variable Overhead Spending Variance

The variable overhead spending variance is the difference between the actual and budgeted rates of spending on variable overhead. The variance is used to focus attention on those overhead costs that vary from expectations. The formula is:

Actual hours worked x (Actual overhead rate - standard overhead rate)

= Variable overhead spending variance

A favorable variance means that the actual variable overhead expenses incurred per labor hour were less than expected.

In the study guide, CIPS splits overhead variance into volume and expenditure variance. They can be understood as variable and fixed overhead variance respectively.

Explanation

There are many types of barriers to entry into a market. Some of these include:

- Economies of Scale: When manufacturing or selling at a large scale, companies are able to avail cost advantages because per unit costs of the product fall. So the more the company produces in quantity the more the benefit. When existing companies have this advantage, it can act as a barrier to entry because a new entrant will have to try to match the scale to achieve the same cost ad-vantage as the existing company. This may not be possible at the initial stage.

- A Differentiated Product: If the product being sold by the existing company or companies is highly differentiated or enjoys strong brand loyalty, then this can act as a strong barrier to entry. The new entrant will have to invest in creating a product with newer and unique features and bene-fits that surpass those offered by the old company. In addition, there will need to be strong efforts to break existing brand loyalties and shift them to a new untested company.

- High Capital Costs: If an industry requires huge capital investments at the onset, then this will act as a barrier to entry for many of the potential entrants. Only those will attempt to enter the competitive fray who have the resources to make this high initial investment.

- Other Cost Advantages: Apart from those cost benefits that come from economies of scale, there are other advantages that an existing firm may enjoy. These include access to the best suppliers, an understanding of existing materials and knowledge of their quality, possession of any necessary and important patents, and proprietary information and technological knowledge. There are also learning advantages, achieved over years of business and experience.

- Cost of Switching: The cost associated with a consumer’s move from one company or product or another is called the switching cost. If there are significant switching costs, then a new entrant may not be able to create means of removing these. Or, they may have to offer significant advantage to counter these switching costs at their own expense.

- Distribution Network: Often, distribution relationships are well established and may prove to be a strong barrier to entry for a new company. A new entrant will obviously need access to these dis-tribution channels but will need to invest extra in order to engage distributors who have established relations with existing competitors.

- Suppliers: As with distributors, suppliers may be vital to the operations of a new business. Exist-ing suppliers may have contracts or loyalties with existing companies and may prove to be difficult to form relationships with.

- Legal and Government Created Barriers: Government and regulatory requirements such as permits and licenses may be a strong barrier to entry. There may also be laws governing ways to conduct business that may conflict with a company’s practices in other countries.

- Barriers to Exit: Interestingly, barriers to exit may act as a deterrent to entry by new companies. If a company is unable to easily leave a competitive environment in case business does not work out, then it will have to stay and compete even if that is a detrimental business practice. In this case, the company may choose to not enter the market in the first place.

Explanation

Kano model of excitement and basic quality (Kano et al, 1984; Berger et al, 1993; Matzler et al, 1996) brings a different perspective for the analysis of improvement opportunities in products and services because it takes in consideration the asymmetrical and non-linear relationship between performance and satisfaction. The Kano model classifies customers requirements in three categories (figure 3):

a) Basic Requirements (or Must-be requirement). The basic requirements fulfill the basic func-tions of a product. If they are not present or their performance is insufficient, customers will be extremely dissatisfied. On the other hand, if they are present or have sufficient performance, they don't bring satisfaction. Customers see them as prerequisites. For instance, for luxury automobiles, "air bags" are considered basic. A customer won't feel satisfied if the automobile has "air bag", however he/she will not buy it if “air bag” is not present.

b) Performance Requirements (or One-dimensional requirements). As for these requirements, satisfaction is proportional to the performance level – the higher the performance, the higher the customer's satisfaction will be and vice-versa. Gas consumption in automobiles is an example of these requirements. Usually customers explicitly demand performance requirements.

c) Excitement Requirements (or Attractive requirements). These requirements are key to cus-tomer satisfaction. If they are present or have sufficient performance, they will bring superior satisfaction. On the other hand, if they are not present or their performance is insufficient, customers will not get dissatisfied. For instance, a surprise gift at the end of a dinner in a restaurant will certainly bring satisfaction, but it will not cause dissatisfaction if not offered. These requirements are not demanded nor expected by customers.

Two other types of requirements may be identified in the Kano model: neutral and reverse ones. Neutral requirements do not bring either satisfaction or dissatisfaction. Reverse require-ments bring more satisfaction if absent than if present.

Explanation

An Outcome Based Specification (OBS) focuses on the desired outcome of a service in business terms, rather than a detailed technical specification of how the service is to be provided; this allows providers scope to propose innovative solutions that might not have occurred to the procurement team. Outcome should be distinguished from output, which is the measurable results of a set of inputs. The example of difference between outcome and output is written at the bottom of page 123 in the study guide.

Outcomes should be the starting point in making new specification. However, using outcome-based specification has some setbacks:

- First, it is not easy to measure the outcomes. Usually, outcome of a project is a statement like 'increase customer satisfaction', 'maintain ambient temperature' or 'provide a convenient way to do something'. They are not easy to measure as output.

- Second, sometimes the desired outcomes require time to be materialised

- Third, outcomes can be ambiguous

Detailed Explanation:

While substitute products are an important factor, other forces such as new entrants, buyer and supplier bargaining power, and industry rivalry also significantly influence market dynamics. These forces are part of frameworks like Porter’s Five Forces used in market analysis. Reference: CIPS Level 4, Market Environment Analysis.

Detailed Explanation:

Conformance specifications are appropriate when the buyer has precise requirements that must be met. This ensures the final product aligns perfectly with the company’s needs, even if it limits supplier flexibility. Reference: CIPS Level 4, Conformance Specification in Procurement.

Explanation

Internal stakeholders may contribute to defining needs and drafting the specification by using their technical expertise. In this scenario, IT team may consult procurement team on the technical specification of the software, including compatibility with company's current IT system.

With through-life management, buyer not only cares about the physical asset but also other factors like customer services and maintenance.

Explanation

A business case is developed during the early stages of a project and outlines the why, what, how, and who necessary to decide if it is worthwhile continuing a project. One of the first things you need to know when starting a new project are the benefits of the proposed business change and how to communicate those benefits to the business.

Preparing the business case involves an assessment of:

- Business problem or opportunity

- Benefits

- Risk

- Costs including investment appraisal

- Technical solutions

- Timescale

- Impact on operations

- Organizational capability to deliver the project outcomes

These project issues are an important part of the business case. They express the problems with the current situation and demonstrate the benefits of the new business vision. Making business case with multiple options and choices also prompts the procurement and senior management to consider alternatives. As a result, the organisation may opt out the best option.

The business case brings together the benefits, disadvantages, costs, and risks of the current situa-tion and future vision so that executive management can decide if the project should go ahead.
