Key tradeoffs of different structures are presented to help managers design an optimal structure.
HR at SYSCO contributed strategically, operationally, and administratively. As the largest food services company in the US with over 40,000 employees, SYSCO previously had regional HR administering practices separately. To better serve regional needs, corporate HR adopted a "market-driven" approach, identifying ways to assist regions and developing tailored programs. HR gathered data on activities using a virtual resource center to develop initiatives. This included increasing safety to reduce compensation claims by 30% and saving $10 million annually, as well as boosting night shift retention by 20% for $15 million in annual savings. HR also revised pay and incentives for drivers, improving safety records, retention, and customer satisfaction while lowering delivery costs.
This document provides an overview of key topics from Chapter 1 of a research methods textbook.

This is a presentation given in the MBS MSc Innovation Management course taught by Prof. Silvia for group assignment to introduce and discuss the paper Dynamic Capabilities and Strategic Management by Teece D., Pisano G., and Shuen A. in 1997.
The document discusses the role and importance of business research. It defines business research as the systematic and objective process of generating information to aid business decision making. There are two main types of business research: basic research aims to expand knowledge without directly solving problems, while applied research addresses specific real-world problems businesses face. The document outlines factors managers consider when deciding whether to conduct business research, such as time constraints, available data, the nature of the decision, and whether the benefits of research outweigh the costs. It also provides examples of areas of research importance to businesses.
Research begins with identifying a problem or question. It requires a plan to address the main problem through sub-problems. Research seeks direction through hypotheses and assumptions to study facts and their meanings in a circular process. It can be basic or applied, using deductive or inductive approaches with quantitative or qualitative methods. A hypothesis guides the research by suggesting a statement to test through relevant facts and an appropriate design.

Applications of MVA in fields like marketing, quality control, process optimization, and research are also mentioned.
The document describes a study that examined the effects of four different diets on weight gain in rats. Twenty-four rats were given one of four diets that varied in vitamin and protein content over two weeks. The weights were recorded and analyzed using one-way ANOVA and post hoc tests. The analysis found that diet 1 (0.1% vitamin, 10% protein) resulted in significantly greater weight gain than diets 2-4. Diets 2, 3 and 4 were not significantly different from each other in terms of weight gain. Therefore, diet 1 was determined to be the optimal diet for promoting weight gain in rats based on the statistical analysis.
This document discusses statistical analysis using SPSS. It describes descriptive statistics, which present data in a usable form by describing frequency, central tendency, and dispersion. Inferential statistics make broader generalizations from samples to populations using hypothesis testing. Hypothesis testing involves research hypotheses, null hypotheses, levels of significance, and type I and II errors. Choosing an appropriate statistical test depends on the hypothesis and measurement levels of the variables. SPSS is a comprehensive system for statistical analysis that can analyze many file types and generate reports and statistics.
This document outlines a course on multivariate data analysis. It introduces key topics that will be covered, including matrix algebra, the multivariate normal distribution, principal component analysis, factor analysis, cluster analysis, discriminant analysis, and canonical correlations. The course workload consists of 40% theory and 60% practice, including a group project and weekly presentations. R will be the main software used. Examples of multivariate data and applications in various fields like business, health, and education are also provided.
The document discusses factor analysis as an exploratory and confirmatory multivariate technique. It explains that factor analysis is commonly used for data reduction, scale development, and evaluating the dimensionality of variables. Factor analysis determines underlying factors or dimensions from a set of interrelated variables. It reduces a large number of variables to a smaller number of factors. The key steps in factor analysis include computing a correlation matrix, extracting factors, rotating factors, and making decisions on the number of factors.
Factor analysis and cluster analysis are techniques used in research methodology. Factor analysis is used to identify underlying constructs in the data and reduce the number of variables. It uses principal component analysis or common factor analysis. Cluster analysis groups objects into clusters based on correlations or distances between objects. Hierarchical clustering divides objects into clusters while non-hierarchical clustering allows objects to change clusters. Determining the appropriate number of clusters can be done by specifying the number in advance, specifying clustering levels, examining generated clusters, or plotting within and between group variance.
An Introduction to Factor analysis pptMukesh Bisht
This document discusses exploratory factor analysis (EFA). EFA is used to identify underlying factors that explain the pattern of correlations within a set of observed variables. The document outlines the steps of EFA, including testing assumptions, constructing a correlation matrix, determining the number of factors, rotating factors, and interpreting the factor loadings. It provides an example of running EFA on a dataset with 11 physical performance and anthropometric variables from 21 participants. The analysis extracts 3 factors that explain over 80% of the total variance.
This document discusses using one-way ANOVA in SPSS to compare mean salaries among employee age groups. It finds a significant difference in monthly salaries between the three age groups. Post hoc tests show that all three group means are significantly different from one another. Two other examples are presented: the first finds no significant difference in the importance of growth and development between age groups, while the second does find a significant difference in the importance of a safe work environment between the youngest and oldest age groups specifically.
This document discusses analysis of variance (ANOVA) and experimental designs, including complete randomized design (CRD), randomized complete block design (RCBD), and Latin square design (LSD). It provides details on the procedures for ANOVA calculations for one-way and two-way classifications and outlines the advantages and limitations of different experimental designs. The key steps in layout and analysis of a CRD are also demonstrated with an example.
Factor analysis is a technique used to reduce a large set of variables down to a smaller set of underlying factors or components. It can identify hidden constructs or dimensions in a set of data that may not be obvious. For example, when a bank asks customers many questions, factor analysis can group related characteristics like dependability, honesty and reliability into a single "trustworthiness" factor. It provides a concise representation of the data while also identifying interrelationships between variables.
The document provides an overview of factor analysis, including:
- Factor analysis is a statistical technique used to reduce a large number of variables into a smaller number of underlying factors or components according to patterns of correlation between variables.
- The two main types are exploratory factor analysis, which is used when the underlying factors are unknown, and confirmatory factor analysis, which is used to test hypotheses about a predetermined factor structure.
- Key steps in factor analysis include determining the appropriateness of the data, extracting factors using various criteria, rotating factors to improve interpretation, and interpreting the results including factor loadings and communalities.
Factor analysis is a statistical technique used to reduce a large set of variables into a smaller set of underlying factors or dimensions. It examines the interrelationships among variables to define common dimensions called factors that can help explain correlations. Factor analysis is used to identify the underlying structure in a data set and reduce many variables into a smaller number of factors for subsequent analysis like regression or discriminant analysis.
This document discusses various types of analysis of variance (ANOVA) statistical tests. It begins with an introduction to one-way ANOVA for comparing the means of three or more independent groups. Requirements for one-way ANOVA include a nominal independent variable with three or more levels and a continuous dependent variable. Assumptions of one-way ANOVA include normality and homogeneity of variances. The document then briefly discusses two-way ANOVA, MANOVA, ANOVA with repeated measures, and related statistical tests. Examples of each type of ANOVA are provided.

Statistical Power Analysis
• Researchers should always design the study to achieve
a power level of .80 at the desired significance level.
• More stringent significance levels (e.g., .01 instead of .
05) require larger samples to achieve the desired power
level.
• Conversely, power can be increased by choosing a less
stringent alpha level (e.g., .10 instead of .05).
• Smaller effect sizes always require larger sample sizes
to achieve the desired power.
• Any increase in power is most likely achieved by
increased sample size.
