The chapter also covers topics like project planning, scheduling, controlling, and the roles of project managers. An example case study on a large project by Bechtel is provided to illustrate real-world project management.
Project management involves defining goals, planning, implementing, and evaluating a project. It typically involves short-term projects with specific outcomes and allocated resources. Planning is the most important step and involves assessing time, cost, and scope. Two case studies are described: an executive dashboard project completed on time and budget through defining roles and milestones, and a class agent portal rebuild that met its goals through careful project management. Tools and models for prioritizing projects include matrices and Venn diagrams.
The document discusses a lecture on project management. It covers three topics: project structure, critical path method (CPM), and Gantt charts. For project structure, it describes three organizational structures for projects: pure project structure, functional project structure, and mixed project structure. It then explains the critical path method for mapping out the timeline of a project's tasks and identifying its critical path. Finally, it briefly mentions that Gantt charts will also be covered.
The document discusses project management techniques like CPM and PERT. It provides 3 examples of projects to illustrate what constitutes a project. It then defines key aspects of project management like the work breakdown structure, network diagrams, and critical path method. The critical path method is explained through an example network diagram that is analyzed to find the earliest and latest start/finish times, critical path and project duration.
The document discusses key aspects of services marketing. It notes that the service sector makes up a large portion of economic activity and employment in most developed economies. Services range from those provided internally by organizations to their external customers. There are also four main categories of services defined by whether they process people, possessions, mental stimuli, or information. The characteristics of services, including intangibility and variability, have important implications for marketing strategy. Firms must consider customer involvement in production and the role of employees, as well as how to effectively design service delivery processes and channels.

1. Sampling is the process of selecting a subset of items from a population to make inferences about the entire population. It is often used instead of a complete census or enumeration due to the time, cost, and resources required for a census.
2. There are two main types of sampling: probability sampling, where every item has a known, non-zero chance of being selected, and non-probability sampling, where items are selected in a non-random way based on the researcher's judgment.
3. Common probability sampling methods include simple random sampling, systematic sampling, stratified sampling, and cluster sampling. Common non-probability methods include convenience sampling and purposive sampling. The appropriate sampling method depends on the
Hypothesis testing involves making an assumption about an unknown population parameter, called the null hypothesis (H0). A hypothesis is tested by collecting a sample from the population and comparing sample statistics to the hypothesized parameter value. If the sample value differs significantly from the hypothesized value based on a predetermined significance level, then the null hypothesis is rejected. There are two types of errors that can occur - type 1 errors occur when a true null hypothesis is rejected, and type 2 errors occur when a false null hypothesis is not rejected. Hypothesis tests can be one-tailed, testing if the sample value is greater than or less than the hypothesized value, or two-tailed, testing if the sample value is significantly different from the hypothesized value.
This document discusses statistical inference, which involves drawing conclusions about an unknown population based on a sample. There are two main types of statistical inference: parameter estimation and hypothesis testing. Parameter estimation involves obtaining numerical values of population parameters from a sample, like estimating the percentage of people aware of a product. Hypothesis testing involves making judgments about assumptions regarding population parameters based on sample data. The document also discusses point estimation, interval estimation, standard error, and provides examples of calculating confidence intervals.
1. Sampling is the process of selecting a subset of items from a population to gather information about the entire population. It involves selecting a sample using probability or non-probability methods.
2. Probability sampling methods like simple random sampling, systematic sampling, and stratified sampling ensure each item has a known, non-zero chance of being selected. Non-probability methods like convenience sampling and purposive sampling rely on researcher judgment.
3. The central limit theorem states that as sample size increases, the sample mean will approach a normal distribution, allowing inferences about the population mean from a sample. Sampling error is reduced with larger sample sizes.
L3 sampling fundamentals and estimationJags Jagdish
This document discusses key concepts in sampling fundamentals. It defines statistics and parameters, with statistics describing characteristics of a sample and parameters describing characteristics of a population. It provides formulas for calculating the sample mean, sample variance, population mean, and population variance. It also explains the law of large numbers, where the sample mean gets closer to the population mean as the sample size increases, and the central limit theorem, where the sample mean approaches a normal distribution as the sample size increases.
This document provides examples and explanations of common hypothesis testing techniques including:
- Z tests for large samples with known population variance to test claims about population means
- T tests for small samples with unknown population variance
- Tests comparing two population means using Z tests for large samples and T tests for small samples
- One-tailed and two-tailed tests at various significance levels (e.g. 5%, 10%)
Step-by-step solutions and calculations are shown for multiple examples testing claims about means, differences in means, and whether sample data is consistent with hypothesized population parameters.
This document discusses different methods for collecting primary data, including observation, interviews, questionnaires, and schedules. It provides details on each method, such as advantages and limitations. Some key points covered include:
- Primary data is originally collected for the specific research purpose, while secondary data was previously collected by others.
- Observation allows collecting data without respondent bias but provides limited information. Interviews can obtain more depth but are more expensive and time-consuming.
- Questionnaires standardize responses but response rates may be low. They are cheaper than interviews and can reach more geographically dispersed respondents.
This document discusses the chi-square test and how to calculate expected frequencies. It provides an example of using a chi-square test to analyze observed vs expected frequencies of blood types in children with one parent of type A and one of type B. It also gives another example using a chi-square test to analyze the effectiveness of vaccination in preventing smallpox attacks using a 2x2 contingency table.
Distribution channel &_physical_distribution.pptx [repaired]Jags Jagdish
Distribution channels involve intermediaries that make products available to consumers. They include manufacturers, distributors, wholesalers and retailers. Physical distribution systems contain elements like warehousing, transportation, inventory control and order processing. Warehousing involves storage and redistribution of goods. Transportation choices affect costs and delivery. Inventory decisions balance risks of stockouts and carrying costs. Order processing prepares and fulfills customer orders.
This document outlines the new product development process, including 7 key stages: 1) idea generation, 2) idea screening, 3) concept development and testing, 4) business analysis, 5) product development, 6) market testing, and 7) commercialization. It describes the activities that occur at each stage, such as generating ideas from customers and employees, evaluating ideas, developing product concepts, analyzing business feasibility, testing concepts with customers, and launching the product in select markets. The goal is to systematically evaluate and refine new product ideas before full commercialization.
1) Marketing communication is how firms inform, persuade, and remind consumers about products and brands using communications processes like advertising, publicity, personal selling, sales promotion, and direct marketing.
2) The promotion mix refers to these promotional tools and considers objectives, audiences, costs, and strategies for each element.
3) An integrated marketing communications plan links marketing and communication functions to deliver effective and coordinated messages across different channels.
Supply chain management involves integrating suppliers, manufacturers, warehouses, and distribution centers so that the right products are delivered to the right places at the right time for the lowest system-wide cost. It is challenging due to uncertainties in factors like travel times, weather, and politics. McDonald's success demonstrates effective supply chain management through its tiered supplier system and distribution centers that ensure fast delivery to restaurants while managing return logistics and quality.
Chapter 10. distribution channel & logistics managementJags Jagdish
This document discusses key concepts in distribution channel and logistics management. It defines distribution channels and marketing strategies like push and pull. It also outlines categories of buyers, levels of distribution channels, functions of channels, and decisions around selecting and managing channel members. The document then discusses marketing systems like vertical marketing systems and franchising. It concludes by covering logistics elements such as warehousing, transportation, inventory control and order processing.
This document discusses the concept of services and service quality. It defines what a service is and highlights some key distinctive characteristics of services, including intangibility, inseparability, variability, and perishability. It contrasts services with goods. The document then discusses three types of marketing for service industries and identifies five key dimensions of service quality - reliability, responsiveness, assurance, empathy, and tangibles. It provides examples of determinants of perceived service quality and outlines a commonly used framework for measuring service quality called SERVQUAL.
This document discusses key concepts in personal selling and sales management. It defines sales management as planning, directing, and controlling personal selling activities like recruiting, training, and motivating salespeople. It also distinguishes marketing from selling, outlines qualities of a successful salesperson, and describes the personal selling process from prospecting to closing the sale. Finally, it identifies important functions in sales force management.
Customer Relationship Management (CRM) is a business strategy that aims to understand, anticipate, and manage customer needs. It involves strategic, process, organizational, and technological changes to better manage a company around customer information. CRM can help companies retain existing customers, attract new customers, improve response times, meet customer requirements, and increase customer satisfaction and revenue while reducing costs. Successful CRM relies on understanding customer expectations, building service partnerships, empowering employees, and implementing total quality management.
Retailing involves activities used to sell products or services to consumers for personal use. Key aspects of retailing include selecting store locations, sourcing and buying merchandise, store management, and building customer relationships. Successful retailers understand customer interests, apply technology to improve operations, and provide good service. Major retailers worldwide include Walmart, Amazon, Tesco, and Carrefour. India is also a major retail market, though smaller than markets like the US and China.
Marketing research involves the systematic design, collection, analysis and reporting of data to help solve specific marketing problems. It uses both primary and secondary data collected through various methods like questionnaires, interviews and observations. The data is then analyzed using statistical tools to help marketing managers make better decisions regarding segmentation, targeting, and developing effective marketing strategies and programs.

What is project management
• The application of a collection of tools and techniques
to direct the use of diverse resources towards the
accomplishment of a unique, complex, one time task
within time, cost and quality constraints.
• Its origins lie in World War II, when the military
authorities used the techniques of operational research
to plan the optimum use of resources.
• One of these techniques was the use of networks to
represent a system of related activities
7. vikramthadeshvar@hotmail.com 7
Project Management Process
• Project planning
• Project scheduling
• Project control
• Project team
– made up of individuals from various areas and departments within a
company
• Matrix organization
– a team structure with members from functional areas, depending on skills
required
• Project Manager
– most important member of project team
• Scope statement
– a document that provides an understanding, justification, and expected result
of a project
• Statement of work
– written description of objectives of a project
• Organizational Breakdown Structure
– a chart that shows which organizational units are responsible for work items
• Responsibility Assignment Matrix
– shows who is responsible for work in a project
8. vikramthadeshvar@hotmail.com 8
Work breakdown structure
• A method of breaking down a project into individual
elements ( components, subcomponents, activities and
tasks) in a hierarchical structure which can be scheduled
and cost
• It defines tasks that can be completed independently of
other tasks, facilitating resource allocation, assignment
of responsibilities and measurement and control of the
project
• It is foundation of project planning
• It is developed before identification of dependencies and
estimation of activity durations
• It can be used to identity the tasks in the CPM and PERT
10. vikramthadeshvar@hotmail.com 10
Project Planning
• Resource Availability and/or Limits
– Due date, late penalties, early completion
incentives
– Budget
• Activity Information
– Identify all required activities
– Estimate the resources required (time) to complete
each activity
– Immediate predecessor(s) to each activity needed
to create interrelationships

History of CPM/PERT
• Critical Path Method (CPM)
– E I Du Pont de Nemours & Co. (1957) for construction of new
chemical plant and maintenance shut-down
– Deterministic task times
– Activity-on-node network construction
– Repetitive nature of jobs
• Project Evaluation and Review Technique (PERT)
– U S Navy (1958) for the POLARIS missile program
– Multiple task time estimates (probabilistic nature)
– Activity-on-arrow network construction
– Non-repetitive jobs (R & D work)
14. vikramthadeshvar@hotmail.com 14
Project Network
• Network analysis is the general name given to certain specific
techniques which can be used for the planning, management and
control of projects
• Use of nodes and arrows
Arrows An arrow leads from tail to head directionally
– Indicate ACTIVITY, a time consuming effort that is required to perform a
part of the work.
Nodes A node is represented by a circle
- Indicate EVENT, a point in time where one or more activities start and/or
finish.
• Activity
– A task or a certain amount of work required in the project
– Requires time to complete
– Represented by an arrow
• Dummy Activity
– Indicates only precedence relationships
– Does not require any time of effort
15. vikramthadeshvar@hotmail.com 15
• Event
– Signals the beginning or ending of an activity
– Designates a point in time
– Represented by a circle (node)
• Network
– Shows the sequential relationships among activities using nodes
and arrows
Activity-on-node (AON)
nodes represent activities, and arrows show precedence
relationships
Activity-on-arrow (AOA)
arrows represent activities and nodes are events for points in
time

For clarity, this list is kept to a minimum by specifying only
immediate relationships, that is relationships involving activities
that "occur near to each other in time".
21. vikramthadeshvar@hotmail.com 21
Questions to prepare activity network
• Is this a Start Activity?
• Is this a Finish Activity?
• What Activity Precedes this?
• What Activity Follows this?
• What Activity is Concurrent with this?
22. vikramthadeshvar@hotmail.com 22
CPM calculation
• Path
– A connected sequence of activities leading from
the starting event to the ending event
• Critical Path
– The longest path (time); determines the project
duration
• Critical Activities
– All of the activities that make up the critical path
23. vikramthadeshvar@hotmail.com 23
Forward Pass
• Earliest Start Time (ES)
– earliest time an activity can start
– ES = maximum EF of immediate predecessors
• Earliest finish time (EF)
– earliest time an activity can finish
– earliest start time plus activity time
EF= ES + t
Latest Start Time (LS)
Latest time an activity can start without delaying critical path
time
LS= LF - t
Latest finish time (LF)
latest time an activity can be completed without delaying
critical path time
LS = minimum LS of immediate predecessors
Backward Pass
24. vikramthadeshvar@hotmail.com 24
CPM analysis
• Draw the CPM network
• Analyze the paths through the network
• Determine the float for each activity
– Compute the activity’s float
float = LS - ES = LF - EF
– Float is the maximum amount of time that this activity can be
delay in its completion before it becomes a critical activity,
i.e., delays completion of the project
• Find the critical path is that the sequence of activities and events
where there is no “slack” i.e.. Zero slack
– Longest path through a network
• Find the project duration is minimum project completion time
33. vikramthadeshvar@hotmail.com 33
PERT
• PERT is based on the assumption that an activity’s duration
follows a probability distribution instead of being a single value
• Three time estimates are required to compute the parameters of
an activity’s duration distribution:
– pessimistic time (tp) - the time the activity would take if
things did not go well
– most likely time (tm) - the consensus best estimate of the
activity’s duration
– optimistic time (to) - the time the activity would take if things
did go well
Mean (expected time): te =
tp + 4 tm + to
6
Variance: Vt =σ 2
=
tp - to
6
2
34. vikramthadeshvar@hotmail.com 34
PERT analysis
• Draw the network.
• Analyze the paths through the network and find the critical path.
• The length of the critical path is the mean of the project duration
probability distribution which is assumed to be normal
• The standard deviation of the project duration probability
distribution is computed by adding the variances of the critical
activities (all of the activities that make up the critical path) and
taking the square root of that sum
• Probability computations can now be made using the normal
distribution table.

Cost consideration in project
• Project managers may have the option or requirement to crash the
project, or accelerate the completion of the project.
• This is accomplished by reducing the length of the critical
path(s).
• The length of the critical path is reduced by reducing the duration
of the activities on the critical path.
• If each activity requires the expenditure of an amount of money
to reduce its duration by one unit of time, then the project
manager selects the least cost critical activity, reduces it by one
time unit, and traces that change through the remainder of the
network.
• As a result of a reduction in an activity’s time, a new critical path
may be created.
• When there is more than one critical path, each of the critical
paths must be reduced.
• If the length of the project needs to be reduced further, the
44. vikramthadeshvar@hotmail.com 44
Project Crashing
• Crashing
– reducing project time by expending additional resources
• Crash time
– an amount of time an activity is reduced
• Crash cost
– cost of reducing activity time
• Goal
– reduce project duration at minimum cost
46. vikramthadeshvar@hotmail.com 46
Time-Cost Relationship
Crashing costs increase as project duration decreases
Indirect costs increase as project duration increases
Reduce project length as long as crashing costs are less than

Benefits of CPM/PERT
• Useful at many stages of project management
• Mathematically simple
• Give critical path and slack time
• Provide project documentation
• Useful in monitoring costs
•How long will the entire project take to be completed? What are the
risks involved?
•Which are the critical activities or tasks in the project which could
delay the entire project if they were not completed on time?
•Is the project on schedule, behind schedule or ahead of schedule?
•If the project has to be finished earlier than planned, what is the best
way to do this at the least cost?
CPM/PERT can answer the following important
questions:
51. vikramthadeshvar@hotmail.com 51
Limitations to CPM/PERT
• Clearly defined, independent and stable activities
• Specified precedence relationships
• Over emphasis on critical paths
• Deterministic CPM model
• Activity time estimates are subjective and depend on judgment
• PERT assumes a beta distribution for these time estimates, but
the actual distribution may be different
• PERT consistently underestimates the expected project
completion time due to alternate paths becoming critical
To overcome the limitation, Monte Carlo simulations can be
performed on the network to eliminate the optimistic bias
