Process Analysis Techniques Qualitative analysis • Value-Added Analysis • Root-Cause Analysis • Pareto Analysis • Issue Register Quantitative Analysis • Quantitative Flow Analysis • Queuing Theory • Process Simulation Dr. R. Umarani Assistant Professor 4
Purposes of Qualitative Analysis Identify and eliminate waste • Valued-added analysis Identify, understand prioritize issues • Issue register • Root-cause analysis (e. g. cause-effect diagrams) • Pareto analysis Dr. R. Umarani Assistant Professor 5
Eliminating Waste "All we are doing is looking at the time line, from the moment the customer gives us an order to the point when we collect the cash. And we are reducing the time line by reducing the non-value-adding wastes ” Taiichi Ohno Dr. R. Umarani Assistant Professor 6
7+1 Sources of Waste 1. 2. 3. 4. 5. Unnecessary Transportation (send, receive) Inventory (large work-in-process) Motion (drop-off, pick-up, go to) Waiting (waiting time between tasks) Over-Processing (performing what is not yet needed or might not be needed) 6. Over-Production (unnecessary cases) 7. Defects (rework to fix defects) 8. Resource underutilization (idle resources) Dr. R. Umarani Assistant Professor 7
Value-Added Analysis 1. Decorticate the process into steps 2. Classify each step into: – Value-adding (VA): Produces value or satisfaction to the customer. • Is the customer willing to pay for this step? – Business value-adding (BVA): Necessary or useful for the business to run smoothly, or required due to the regulatory environment, e. g. checks, controls • Would the business potentially suffer in the long-term if this step was removed? – Non-value-adding (NVA) – everything else including handovers, delays and rework Dr. R. Umarani Assistant Professor 8

Admission Process Consider the following process for the admission of graduate students at a university. In order to apply for admission, students first fill in an online form. Online applications are recorded in an information system to which all staff members involved in the admissions process have access to. After a student has submitted the online form, a PDF document is generated and the student is requested to download it, sign it, and send it by post together with the required documents, which include: 1. Certified copies of previous degree and academic transcripts. 2. Results of English language test. 3. Curriculum vitae. When these documents are received by the admissions office, an officer checks the completeness of the documents. If any document is missing, an e-mail is sent to the student. The student has to send the missing documents by post. Assuming the application is complete, the admissions office sends the certified copies of the degrees to an academic recognition agency, which checks the degrees and gives an assessment of their validity and equivalence in terms local education standards. This agency requires that all documents be sent to it by post, and all documents must be certified copies of the originals. The agency sends back its assessment to the university by post as well. Assuming the degree verification is successful, the English language test results are then checked online by an officer at the admissions office. If the validity of the English language test results cannot be verified, the application is rejected (such notifications of rejection are sent by e-mail). Once all documents of a given student have been validated, the admission office forwards these documents by internal mail to the corresponding academic committee responsible for deciding whether to offer admission or not. The committee makes its decision based on the academic transcripts and the CV. The committee meets once every 2 to 3 weeks and examines all applications that are ready for academic assessment at the time of the meeting. At the end of the committee meeting, the chair of the committee notifies the admissions office of the selection outcomes. This notification includes a list of admitted and rejected candidates. A few days later, the admission office notifies the outcome to each candidate via e-mail. Additionally, successful candidates are sent a confirmation letter by post. Dr. R. Umarani Assistant Professor 11
Techniques for issue analysis • Cause-effect diagrams • Why-why diagrams • Pareto charts Dr. R. Umarani Assistant Professor 12
Cause-Effect (Fishbone) Diagrams Dr. R. Umarani Assistant Professor 13
Cause-effect diagram (rejected equipment) Dr. R. Umarani Assistant Professor 14
Why-Why Diagram Dr. R. Umarani Assistant Professor 15
Why-why diagram (equipment rental) Site engineers keep equipment longer, why? • Site engineer fears that equipment will not be available later when needed, why? – time between request and delivery too long, why? • excessive time spent in finding a suitable equipment and approving the request, why? – time spent by clerk contacting possibly multiple suppliers sequentially; – time spent waiting for works engineer to check the requests; Dr. R. Umarani Assistant Professor 16
Issue Documentation and Impact Assessment -Issue Register • Purpose: to categorise identified issues as part of asis process modelling • Output of root cause analysis by providing a more detailed analysis of individual issues and their impact. • The impact of issue is measured quantitatively and qualitatively • Quantitative – time or money lost • Qualitative – perceived nuisances to the customer Dr. R. Umarani Assistant Professor 17
Issue Register 1. 2. 3. 4. Name of the issue : 2 -5 words Description : 1 -2 sentences Priority : 1, 2, 3 Assumptions or input data: made in impact 5. Qualitative impact 6. Quantitative impact Dr. R. Umarani Assistant Professor 18
Issue Register (Equipment Rental) Dr. R. Umarani Assistant Professor 19
Pareto Analysis - Issue register will serve for Pareto analysis - Aim of Pareto analysis is to identify which issues or which causal factors of an issue should be given priority - Sometimes this principle is also called the 80 -20 principle ie. 20% of issues are responsible for 80% of the effect Dr. R. Umarani Assistant Professor 20
Pareto Analysis – Typical approach - Define the effect to be analysed and the measure via which of this effect will be quantified like financial loss for the customer or business, time loss, no. of occurrences. - Identify all relevant issues that contribute to the effect to be analysed - Quantify each issue according to the chosen measure - Sort the issues from highest to lowest - Draw a Pareto chart Dr. R. Umarani Assistant Professor 21
Pareto chart • Useful to prioritize a collection of issues or factors behind an issue • Bar chart where the height of the bar denotes the impact of each issue • Bars sorted by impact • Superposed curve where the y-axis represents the cumulative percentage impact Dr. R. Umarani Assistant Professor 22
Pareto chart (excessive rental expenses) Dr. R. Umarani Assistant Professor 23
PICK Chart - A type of chart that can be used as a complement to Pareto charts in order to take into account the difficult dimension is the PICK chart. Dr. R. Umarani Assistant Professor 24

Quantitative Process Analysis - Is Valuable tool to gain systematic insights into a process. Dr. R. Umarani Assistant Professor 27
1. Performance Measures 1. 1 Process Performance Measures • Link the identified processes to measurable objectives • Quantify the benefits of improvement Dr. R. Umarani Assistant Professor 28
Fill in the blanks If you had to choose between two services, you would typically choose the one that is: • F… • B… • C… Dr. R. Umarani Assistant Professor 29
Process Performance Measures Cost Time Quality Cost per execution Cycle time Error rates (negative outcomes, wrong info) Resource utilization Waiting time / time spent in non-valueadded tasks Missed promise Waste Flexibility Dr. R. Umarani Assistant Professor 30
Key Performance Indicators (KPI) • • Time Cost Quality Flexibility Dr. R. Umarani Assistant Professor 31
Let’s start with time Dr. R. Umarani Assistant Professor 32
Cycle Time Analysis • Cycle time: Difference between a job’s start and end time • Cycle time analysis: the task of calculating the average cycle time for an entire process or process fragment – Assumes that the average activity times for all involved activities are available (activity time = waiting time + processing time) • In the simplest case a process consists of a sequence of activities on a sequential path – The average cycle time is the sum of the average activity times • … but in general we must be able to account for – Alternative paths (XOR splits) – Parallel paths (AND splits) – Rework (cycles) Dr. R. Umarani Assistant Professor 33
Cost - Performance measure in analysing and redesigning a business process that has financial nature - Fixed Cost - Variable Cost - Operating Cost Dr. R. Umarani Assistant Professor 34
Quality - Client side Process participant side External quality Internal quality Dr. R. Umarani Assistant Professor 35
Flexibility - Ability of resources to execute different tasks within a business process setting - Ability of a business process as a whole to handle various cases and changing workloads - Ability of the management in charge to change the used structure and allocation rules - Ability to change the structure and responsiveness of the business process Ø Run time flexibility Ø Build time flexibility Dr. R. Umarani Assistant Professor 36
1. 2. Balanced Score Card • Financial Measures • Internal Business Measures • Innovation and Learning Measures • Customer Measure Top Down Procedure ØCorporate ØDepartment ØLower Dr. R. Umarani Assistant Professor 37
Case Scenario A restaurant has recently lost many customers due to poor customer service. The management team has decided to address this issue first of by focusing on the delivery of meals. The team gathered data by asking customers about how quickly they liked to receive their meals and what they considered as an acceptable wait. The data suggested that half of the customers would prefer their meals to be served in 15 minutes or less. All Customers agreed that a waiting time of 30 minutes or more is unacceptable. Dr. R. Umarani Assistant Professor 38
1. 3. Reference Models and Industry Benchmarks • Supply chain operations reference model(SCOR) ØPurchase order cycle time ØInventory management • Process classification framework ØStandardised names and definitions for the process Dr. R. Umarani Assistant Professor 39
2. Flow Analysis • Family of techniques that allow us to estimate the overall performance of a process given some knowledge about the performance of its activities Dr. R. Umarani Assistant Professor 40
2. 1. Calculating cycle time using flow analysis A (10) Dr. R. Umarani Assistant Professor B (20) 41
Alternative Paths CT = p 1 T 1+p 2 T 2+…+pn. Tn = Dr. R. Umarani Assistant Professor 42
Alternative Paths – Example - What is the average cycle time? Dr. R. Umarani Assistant Professor 43
Parallel Paths • If two activities related to the same job are done in parallel the contribution to the cycle time for the job is the maximum of the two activity times. CTparallel = Max{T 1, T 2, …, TM} Dr. R. Umarani Assistant Professor 44
Parallel Paths – Example - What is the average cycle time? Dr. R. Umarani Assistant Professor 45
Rework - Many processes include control or inspection points where if the job does not meet certain standard, it is sent back for rework CT = T/(1 -r) Dr. R. Umarani Assistant Professor 46
Rework – Example - What is the average cycle time? Dr. R. Umarani Assistant Professor 47
Rework At Most Once – Example - What is the average cycle time? Dr. R. Umarani Assistant Professor 48
Quick exercise • Calculate cycle time Dr. R. Umarani Assistant Professor 49
2. 2. Cycle Time Efficiency • Measured as the percentage of the total cycle time spent on value adding activities. Cycle Time Efficiency = • CT = cycle time as defined before • Theoretical Cycle Time (TCT) is the cycle time if we only counted value-adding activities and excluded any waiting time or handover time – Count only processing times Dr. R. Umarani Assistant Professor 50
2. 3. Cycle Time and WIP - CT related to arrival rate and WIP - WIP = Arrival rate * CT Dr. R. Umarani Assistant Professor 51
3. Limitations of flow analysis Limitation 1: Not all Models are Structured Dr. R. Umarani Assistant Professor 52
Limitation 2: Fixed load + fixed resource capacity • Cycle time analysis does not consider waiting times due to resource contention • Queuing analysis and simulation address these limitations and have a broader applicability Dr. R. Umarani Assistant Professor 53
Cycle Time & Work-In-Progress • WIP = (average) Work-In-Process – Number of cases that are running (started but not yet completed) – E. g. # of active and unfilled orders in an order-to-cash process • WIP is a form of waste (cf. 7+1 sources of waste) • Little’s Formula: WIP = ·CT – = arrival rate (number of new cases per time unit) – CT = cycle time Dr. R. Umarani Assistant Professor 54
Exercise A fast-food restaurant receives on average 1200 customers per day (between 10: 00 and 22: 00). During peak times (12: 0015: 00 and 18: 00 -21: 00), the restaurant receives around 900 customers in total, and 90 customers can be found in the restaurant (on average) at a given point in time. At non-peak times, the restaurant receives 300 customers in total, and 30 customers can be found in the restaurant (on average) at a given point in time. 1. What is the average time that a customer spends in the restaurant during peak times? 2. What is the average time that a customer spends in the restaurant during non-peak times? Dr. R. Umarani Assistant Professor 55
Exercise (cont. ) - The restaurant plans to launch a marketing campaign to attract more customers. However, the restaurant’s capacity is limited and becomes too full during peak times. What can the restaurant do to address this issue without investing in extending its building? Dr. R. Umarani Assistant Professor 56
Why flow analysis is not enough? Flow analysis does not consider waiting times due to resource contention Queuing analysis and simulation address these limitations and have a broader applicability Dr. R. Umarani Assistant Professor 57
Why is Queuing Analysis Important? • Capacity problems are very common in industry and one of the main drivers of process redesign – Need to balance the cost of increased capacity against the gains of increased productivity and service • Queuing and waiting time analysis is particularly important in service systems – Large costs of waiting and of lost sales due to waiting Prototype Example – ER at a Hospital • • • Ø Patients arrive by ambulance or by their own accord One doctor is always on duty More patients seeks help longer waiting times Question: Should another MD position be instated? Dr. R. Umarani Assistant Professor 58
Delay is Caused by Job Interference Deterministic traffic Variable but spaced apart traffic Queuing occurs every time user demand exceeds server capacity. Delays are due to several reasons. Let’s Dr. R. Umarani examine some of them… Assistant Professor 59
Burstiness Causes Interference - Queuing results from variability in service times and/or interarrival intervals What does “bursty traffic” mean? Dr. R. Umarani Assistant Professor 60
Job Size Variation Causes Interference Arrivals are deterministic (e. g. the intervals between 2 consecutive arrivals are always the same), however some jobs are longer than others Dr. R. Umarani Assistant Professor 61
High Utilization Exacerbates Interference The queuing probability increases as the load increases Utilization close to 100% is unsustainable too long queuing times Delay probability is higher under heavy loading conditions than when the traffic is light Dr. R. Umarani Assistant Professor 62
The Poisson Process • Common arrival assumption in many queuing and simulation models • The times between arrivals are independent, identically distributed and exponential – P (arrival < t) = 1 – e-λt • Key property: The fact that a certain event has not happened tells us nothing about how long it will take before it happens – e. g. , P(X > 40 | X >= 30) = P (X > 10) Dr. R. Umarani Assistant Professor 63
Negative Exponential Distribution Dr. R. Umarani Assistant Professor 64
Queuing theory: basic concepts Arrivals waiting service c Basic characteristics: • (mean arrival rate) = average number of arrivals per time unit • (mean service rate) = average numberof jobs that can be handled by one server per time unit: • c = number of servers Dr. R. Umarani Assistant Professor 65
Queuing theory concepts (cont. ) Dr. R. Umarani Assistant Professor 66
M/M/1 queue Dr. R. Umarani Assistant Professor 67
M/M/c queue - Now there are c servers in parallel, so the expected capacity per time unit is then c* Little’s Formula Wq=Lq/ L= W W=Wq+(1/ ) Little’s Formula Dr. R. Umarani Assistant Professor 68
Tool Support • For M/M/c systems, the exact computation of Lq is rather complex… • Consider using a tool, e. g. – http: //apps. business. ualberta. ca/aingolfsson/qtp/ – http: //www. stat. auckland. ac. nz/~stats 255/qsim. html Dr. R. Umarani Assistant Professor 69
Example – ER at County Hospital Ø Situation – Patients arrive according to a Poisson process with intensity ( the time between arrivals is exp( ) distributed. – The service time (the doctor’s examination and treatment time of a patient) follows an exponential distribution with mean 1/ (=exp( ) distributed) The ER can be modeled as an M/M/c system where c=the number of doctors Ø Data gathering = 2 patients per hour = 3 patients per hour v Question – Should the capacity be increased from 1 to 2 doctors? Dr. R. Umarani Assistant Professor 70
Queuing Analysis – Hospital Scenario • Interpretation – To be in the queue = to be in the waiting room – To be in the system = to be in the ER (waiting or under treatment) • Is it warranted to hire a second doctor ? Dr. R. Umarani Assistant Professor 71
Process Simulation • Drawbacks of queuing theory: – Generally not applicable when system includes parallel activities – Requires case-by-case mathematical analysis – Assumes “steady-state” (valid only for “long-term” analysis) • Process simulation is more versatile (also more popular) • Process simulation = run a large number of process instances, gather data (cost, duration, resource usage) and calculate statistics from the output Dr. R. Umarani Assistant Professor 72
Process Simulation Steps in evaluating a process with simulation 1. Model the process (e. g. BPMN) 2. Enhance the process model with simulation info simulation model • Based on assumptions or better based on data (logs) 3. Run the simulation 4. Analyze the simulation outputs 1. Process duration and cost stats and histograms 2. Waiting times (per activity) 3. Resource utilization (per resource) 5. Repeat for alternative scenarios Dr. R. Umarani Assistant Professor 73
Elements of a simulation model • The process model including: – Events, activities, control-flow relations (flows, gateways) – Resource classes (i. e. lanes) • Resource assignment – Mapping from activities to resource classes • Processing times – Per activity or per activity-resource pair • Costs – Per activity and/or per activity-resource pair • Arrival rate of process instances • Conditional branching probabilities (XOR gateways) Dr. R. Umarani Assistant Professor 74
Simulation Example – BPMN model Dr. R. Umarani Assistant Professor 75
Resource Pools (Roles) • Two options to define resource pools – Define individual resources of type clerk – Or assign a number of “anonymous” resources all with the same cost • E. g. – 3 anonymous clerks with cost of € 10 per hour, 8 hours per day – 2 individually named clerks • Jim: € 12. 4 per hour • Mike: € 14. 8 per hour – 1 manager John at € 20 per hour, 8 hours per day Dr. R. Umarani Assistant Professor 76
Resource pools and execution times Dr. R. Umarani Assistant Professor 77
Reminder: Normal Distribution Dr. R. Umarani Assistant Professor 78
Arrival rate and branching probabilities 10 applications per hour (one at a time) Poisson arrival process (negative exponential) Alternative: instead of branching probabilities one can assign “conditional expressions” to the branches based on input data Dr. R. Umarani Assistant Professor 79

Process Redesign - Rethinking and Reorganising business processes with the specific purpose of making them perform better. Dr. R. Umarani Assistant Professor 84
1. The Essence of Process Redesign 1. 1. Why Redesign? -Business process creates and delivers a certain product or service that customers are after. -If someone like to improve the quality of such a product or service from the perspective of a customer, arguably the best way to do that is to improve the related business process. - For Eg. - clerk forgets to carry out a particular quality check - Marketing department introduces a special offer for a particular type of customers - Internal auditing department demands at some point that the monetary value of certain financial activities are reported when it is carried out Dr. R. Umarani Assistant Professor 85
1. 2. What is Redesign? Important reasons for redesign; - Internal and external customers of the business process - Business process operation view - Business process behaviour view - Organisation and participants in the business process - Information that the business process uses or creates - Technology the business process uses - External environment the process is situated Dr. R. Umarani Assistant Professor 86
1. 3. The Devil’s Quadrangle Dr. R. Umarani Assistant Professor 87
Devil’s Quadrangle - Ideally a business process redesign decreases the time required to handle a case, it lowers the required cost of executing the process, it improves the quality of the service delivered and it increases the ability of the business process to deal with variation Dr. R. Umarani Assistant Professor 88
1. 4. How to Redesign? Methodology : as a collection of problem solving methods governed by a set of principles and a common philosophy for solving targeted problems. Technique: a set of precisely described procedures for achieving a standard task. Tool: Computer software package to support one or more techniques. Dr. R. Umarani Assistant Professor 89
