5
Comparative to market growth
A market analysis studies the attractiveness and the dynamics of a special market within a special industry. It is part of the industry analysis and thus in turn of the global environmental analysis. Through all of these analyses, the strengths, weaknesses, opportunities and threats (SWOT) of a company can be identified. Finally, with the help of a SWOT analysis, adequate business strategies of a company will be defined
6
Markov Analysis 'Markov Analysis' A method used to forecast the value of a variable whose future value is independent of its past history.

Reducing procurement costs Improving efficiency Monitoring compliance
Spend analysis It is the process of collecting, cleansing, classifying and analyzing expenditure data with the following purpose. Reducing procurement costs Improving efficiency Monitoring compliance
9
Spend analysis Companies perform spend analysis mainly for profitability, In addition to improving compliance and reducing cycle times it helps companies find new areas of savings and maintain savings that they have already negotiated
10
Total Cost of Ownership
Spend Visibility - Applications How much are you spending? Who are you paying? What are you getting in return? Cash Flow Analysis Operating Capital Total Cost of Ownership
11
supply chain dynamics constrained
Just as in project management, supply chain dynamics are mostly defined by the triple constraints of Time, Quality and Cost. Among the four stages of product life cycle (Introduction, Growth, Maturity and Decline), it is usually the Introduction phase that requires most energy and expenditures.
12
Current market value It is the estimated or quoted price if an asset is offered for sale
13
It is the cost at which an asset is acquired.
Original cost It is the cost at which an asset is acquired.
14
Direct Cost and indirect Cost
Direct labour and direct material used to make a unit of product Indirect cost includes factory or manufacturing overheads, represented as total value or cost per unit
15
Fixed Cost Fixed cost is that portion of the total cost that does not change with change in volume within a certain range. Cost of equipment is an example.
16
Variable Cost The portion of total cost that is incurred only when product is made, for example, direct material and direct labour
17
Cost Of Goods Manufactured
Cost Of Goods Manufactured Cost of all good completed at all stages of manufacturing, but not sold yet Expression for COGM for a given period = Work-In-Process opening inventory + Work-In-Process received – Work-In-Process closing inventory
18
Cost of Goods Sold (COGS)
It is the cost of inventory at the finished goods stage, which is an asset and is expensed to the P&L statement at the time of sale Expression for COGS for a given period = FG opening inventory + FG receipts into inventory – FG inventory closing balance.
19
Gross Margin Gross Margin = Sales – Cost Of Goods Sold
20
Depreciation It is the depletion of value of an asset over a period of time. The remaining value at the end of each period is called the Book Value, which may be equal to, higher or lower than the market value at that time, depending on the nature of the asset
21
Replacement cost It is the current cost of replacing an asset.
22
Variance When the Standard Costing method is used for product costing, variance represents the difference between the estimated standard cost and the actual costs incurred. Variance may be positive (favourable) or negative (unfavourable).
23
overheads and profit margin.
Contribution Margin (CM) Contribution Margin (CM) is the difference between the variable cost and sales price per unit, i.e., the balance amount per unit that is contributed to absorb the fixed costs, overheads and profit margin. $ Units CM Table
24
Breakeven Point or Breakeven Volume
It is the volume of sales at which total cost equals total revenue, i.e., no profit, no loss. With a positive contribution per unit, sales beyond the breakeven point start to accumulate profit. Breakeven is represented by the following equation
25
Chapter 2 Sustainable Growth
MODULE 4 GROWING CISCOM Chapter 2 Sustainable Growth Business Research and Service Institute
26
Improvement Focus: NetSuite Survey
A survey was conducted by Netsuite about strategies and methods for cost reduction. Contrary to common belief that employee downsizing is a common way companies pursue to cut costs, it was found out that it at the very low end. Most companies relied on tools and methodologies, employee training and other approaches. The measure is a composite of results realized and the financial outlay. Manufacturers are under pressure to reduce costs and improve productivity. Improvement methodologies start strong, but eventually employees move on to other issues and production line performance suffers. When it comes to managing delays and other challenges, many manufacturers focus on individual operators in the same way they would a piece of capital equipment.
27
Budget – Roadmap for Development
Budget is the projection of costs, expenses, revenues and margins over a specified period of time, usually the fiscal year. It a very important tool to channel the organization’s resources towards meeting its strategic objectives
28
Measuring Performance - Financial Ratios
Financial Ratios are used to quantify various aspects of business performance in financial terms. Some commonly used ratios are as follows Some Common Financial Ratios Liquidity Ratio or Current Ratio = Current Assets/Current Liabilities Quick Ratio = (Current Asset – Inventory)/Current Liabilities Gross Margin = (Net Sales – COGS)/Net Sales Return On Assets = Net Income/Total Assets Stock Turnover Ratio or Inventory Turns = COGS/Average Inventory
29
P&L Statement P&L Statement measures a company’s performance over a period of time, usually a year. Fiscal year may start from January and end in December, or start in any other month of the year and end 12 months later
30
Balance Sheet It is the snapshot of a company’s financial situation at the end of an accounting period, the same period as for the P&L Statement. On the balance sheet, total assets must equal total liabilities plus owners’ equity, hence the term Balance Sheet.
31
Cash Flow Statement Cash Flow Statement represents the cash inflow and out flow and cash balance for a given period
32
Accrual Accrual is the term used to express a commitment or transaction that crates an asset or a liability, however, the balancing cash flow may not occur at the same time, but may be deferred to a later date. For example, we use electricity, accruing cost every day, although we are billed on a monthly basis
33
Overhead Absorption Overhead absorption is the process of dividing the fixed costs or overheads over the total production volume If the actual volume exceeds the budgeted volume, then the overhead cost is over absorbed or positive absorption variance Conversely, if the actual volume turns out to be less than budget, then the overheads are under-absorbed, meaning that the unabsorbed overhead cost will negatively impact the profit margin
34
Sensitivity Analysis:
A tool or mathematical model to assess the impact of a change in inputs to the output. It is also known as the Uncertainty Analysis as the primary objective is to gauge the impact of uncertainty on the outcome
35
Chapter 3 Best Practices & Bench Marking
MODULE 4 GROWING CISCOM Chapter 3 Best Practices & Bench Marking Business Research and Service Institute
36
Best Practices A best practice is a technique or methodology that, through experience and research, has proven to reliably lead to a desired result
37
Benchmarking Benchmarking is the process of comparing one's business processes and performance metrics to industry bests and best practices from other companies.
38
Measure of sustainable growth
The sustainable growth rate (SGR) is the maximum growth rate that a firm can sustain without having to increase financial leverage. Calculated as: ROE x (1 - dividend-payout ratio)
39
Kaizen – Continuous Improvement
The process of continuous improvement, also referred to as the Japanese term Kaizen, focuses on gradual, steady improvements over a sustained period of time
40
The Toyota Production System (TPS)
The Toyota Production System (TPS) is an integrated socio-technical system, developed by Toyota, that comprises its management philosophy and practices. The TPS organizes manufacturing and logistics for the automobile manufacturer, including interaction with suppliers and customers.
41
Chapter 4 Productivity Tools
MODULE 4 GROWING CISCOM Chapter 4 Productivity Tools Business Research and Service Institute
42
Supply Chain Overview Productivity Basics
Productivity is the ratio between Input and Output Example: comparing two similar machines, producing the same item Machine A: Production = 120 Units, Hours used = 60 Productivity = 2 Units Per hour Machine B: Production = 120 Units, Hours used = 48 Productivity = 2.5 Units Per hour Although both the machines produced the same quantity, machine B demonstrated higher productivity. Supply Chain Overview What is a driver can be an obstacle, depending on how it is managed
43
Supply Chain Overview Productivity Basics (Contd.)
The concept applies to many situations: Material Productivity: Yields on raw materials received from source A versus source B (scrap factor/quality). Capital Productivity: Financial return from investing in Option A versus Option B. Labor Productivity: Effective processes leading to higher results, versus wasteful processes causing productivity loss. Supply Chain Overview What is a driver can be an obstacle, depending on how it is managed
44
Supply Chain Overview Obstacles to Achieving Productivity Complexity
Unclear roles and responsibilities – duplication of effort Lack of Coordination Various part of an organization moving in different directions Lack of training Skills gap to promptly identify and address issues. Supply Chain Overview

47
Lean Process 5S without 5Y is just housekeeping Lean Process refers to elimination of waste, thereby creating more value with less cost and effort.
48
Value Stream Mapping (VSM)
In Value Stream Mapping (VSM), each cost activity is assessed whether it adds value for the customer or for the business. If any activity does neither, then it is a potential candidate for removal
49
Value Chain The concept of Value Chain focuses on analyzing cost and value added at each step of the supply chain with a view to reducing costs, thereby adding value for the customer
50
Gemba Walk Gemba Walk represents the engagement of senior leader in the manufacturing environment where value is created for the customer. The idea is to break down barriers and open communication with the workers and technicians who have valuable insight about process improvement.
51
…You cannot inspect quality into a product
Quality Management (TQM) TQM aims at building quality in the process, so that the dependence on inspection can be minimized., because… …You cannot inspect quality into a product
52
Supply Chain Overview 7 Tools of TQM
Cause-and-effect Diagram (also known as the “Fishbone" or Ishikawa diagram) Check Sheet Control Chart Histogram’ Pareto Chart Scatter Diagram Flow Chart Supply Chain Overview
53
Pareto Analysis Pareto Analysis is an approach to emphasize the significant few versus trivial many, in order to focus improvement efforts for the biggest return. It is also called the 80:20 rule, meaning that 80% of the effect is caused by 20% of factors
54
TQM Approach
55
Multiplier Effect of Defects
Process 100% = % x % x % WISH or HOPE… 87% = % x % x % REALITY (best guess) 74% = % x % x %
56
Just-In-Time Just-In-Time can be defined as an inventory strategy implemented to improve Return on Investment (ROI) by reducing in-process inventory and associated carrying costs. This process is based on the supply at the time of need only, which is driven by a signal, called Kanban.
57
What is Muda? Muda is the Japanese term for waste – it is used in campaigns to remove any source or cause of waste of material or time, in an effort to improve the quality of products at a lower cost
58
Six Sigma Six Sigma quality or reliability level is achieved when the defects or variability is systematically reduced to only 3.4 defects or errors per million opportunities
59
6 ∑ = .00034% Failure, or 3.4 Failures in 1 Million Opportunities
Measure of Dispersion Sigma = Measure of Dispersion in a Normal Distribution 1 Sigma = 1 Standard Deviation 1 ∑ = 67% Probability of Success (33% Failure) 2 ∑ = 93% Probability of Success (7% Failure) 3 ∑ = 98% Probability of Success (2% Failure) 6 ∑ = % Failure, or 3.4 Failures in 1 Million Opportunities Supply Chain Overview
60
Statistical Process Control
Statistical Process Control is a quality management tool which is based on recording the process parameters and product characteristics in order to determine the source of errors or variability and eliminate the root cause. The two main recording formats are Control Charts and Scatter Diagrams
61
Using SPC Data to Determine Process Capability
Process/Equipment Capability Performance data under various conditions Defining UCL/LCL and Probability of Non-Conformance Compare with product quality spec, customer requirement, regulatory requirement Assign equipment to products accordingly Improve common causes as necessary
62
Regulatory requirement + infusion quality:
Tea Packaging: Filler Calibration Regulatory requirement + infusion quality: 2 grams per tea bag Defining UCL/LCL and Probability of Non-Conformance Volumetric filling Gravimetric filling Setting the process mean at target weight + variation in order to ensure minimum required weight, with estimated overfill, part of the product cost.
63
Supply Chain Overview Six Sigma Process: DMAIC Define
selecting high-impact projects and understanding which underlying metric(s) will reflect project success. Measure documenting the current process, validating how it is measured, and assessing baseline performance. Analyze isolates the top causes behind the effect, no more than three in most cases. Improve Controlling or eliminating the causes; focus on process redesign. Control Sustaining the improvement, by irreversible design change – minimum need for monitoring. Supply Chain Overview
64
DMAIC steps C = Control I = Improve A= Analyze M = Measure D = Define
In Six Sigma process improvement, DMAIC steps represent the following. C = Control I = Improve A= Analyze M = Measure D = Define
65
Bull Whip Effect Bull Whip Effect occurs when information is communicated from one step to another in a silo fashion, as it causes distortion and inaccuracy to creep in. Each stage in the supply chain therefore has its own set of numbers which may be different from the actual end-requirement. The Bull Whip Effect can cause inventory excesses or shortages

67
Lean and Six Sigma Together
Together, Lean and Six Sigma have the greatest impact, as Lean focuses on reducing cycle time while Six Sigma focuses on reducing process variability, thereby targeting high, consistent quality at low cost
68
SMED – Single-Minute Exchange of Die
Originate from plastic molding: Dies are pre-hated and cooled off-line, without holding the expensive machine hours. Previous Situation: Injection Molding Press Cost Per Hour (mostly depreciation + allocated factory overhead) = $650/Hours Old Die cooling off before removal = 6 hours Removal time = 1 hour New die installation = 2 hours Heating time = 3 hours Total Unproductive time = 12 hours x 650 = $7800 per exchange of dies Number of die changes in a year = 65 Total Cost die changes per year = 65 x $7800 = $507,000 Side effects: Less flexibility due to large lot size necessary to absorb high switchover cost. Capacity lost to unproductive (wait) time.
69
SMED – Single-Minute Exchange of Die
Improved Situation: Old Die removal (while hot) = 1 hour New Die installation (preheated) = 2 hours Total Unproductive time = 3 hours x 650 = $1950 Number of die changes in a year = 65 Total Cost die change = 65 x $1950 = $126,750 Off-line cooling station = 6 hours x $ 25/hour = $150 x 65 changes = $ 9,750 Total cost per year = $ 126,750 + $ 9720 = $ 136,470 Saving of $ 507,000 - $ = $ 370,530 Side benefits: More flexibility due to smaller lot size possible with shorter set-up time (less hours to absorb). Capacity recovered due to reduction of wait time.
70
SMED – Single-Minute Exchange of Die
The concept applicable to any process which presents a potential for concurrent processing
71
Airbus patents designs for convertible plane
SMED – Single-Minute Exchange of Die Airbus patents designs for convertible plane After two years of scrupulous research, the United States Patent and Trademark Office accepted a patent for one of the strangest designs we've seen for a plane. Airbus's 'convertible' plane designs show a detachable cabin, which would allow passengers to board quickly before being attached to the rest of the aircraft. In a business that's all about timing, the newly patented designs could allow airlines to cut turn around times considerably. The detachable cabin would be removed from the roof with the help of a specialized crane, allowing boarding and disembarkment to happen in record time. The cabin full of arriving passengers would be extracted and replaced by another, already full of people going in the other direction. Speedy!
72
Constraints Management
It is a powerful tool to identify the bottlenecks in a process and apply strategies to resolve the constraints Buffer: Inventory cushion for constrained resources in order to avoid disruption in case of a delay in supply from an upstream process. Rope: The communication going back from the key gateways to the releasing processes, advising them if the pace needs to be increased or decreased, depending on the inventory build at the control points. Drum: The pace of manufacturing or average Takt time – which needs to be maintained in order for the operations to be cost effective and customer oriented Three elements in the process
73
Theory Of Constraint (TOC)
Theory Of Constraint (TOC) developed by Eliyahu M. Goldratt provides a systematic approach to identifying and resolving constraints in business. It is a five-step process Identify the constraint Exploit the constraint Subordinate other resources to the constraint Elevate performance of the constraint Repeat the process for the next constraint
74
Theory Of Constraints - TOC
Constraint is “Something” that is blocking your business from achieving its goal of making more profits Dr. Eliyahu M. Goldratt
75
Types of Constraints Physical Machines Materials Skill Sets People
Money Managerial (Nonphysical) Policies Mindset Culture and Attitude Measures Perception of how to measure progress Behaviors Methods Rules and Procedures Environmental (Nonphysical or Physical) Infrastructure Climate/Weather

BRASI’s 3 Levers for sustainable growth
Bull Whip Effect BRASI’s 3 Levers for sustainable growth If the demand information is not shared centrally, rather in silo fashion from one step to another, then it can get distorted in the process and cause imbalance in inventory and customer service. This is caused Bull Whip Effect. Cash Flow Capacity Customer service
77
What is TOC? Organizations are systems analogous to chains
Resources are links; processes connect them. The weakest link determines the strength of any chain. The constraint determines the strength of the organization: ability to achieve its goal/purpose make more money now and in the future
78
The TOC Process STEP 1: IDENTIFY the system’s constraint(s).
STEP 2: Decide how to EXPLOIT the system’s constraint(s). STEP 3: SUBORDINATE everything else to the above decision. STEP 4: ELEVATE the system’s constraint(s). STEP 5: If in a previous step a constraint has been broken, go back to step 1, but do not allow INERTIA to cause a system’s constraint.

Finished Material Goods A B C D E FG RM 10 9 5 7 8 Capacity (units/day) +/- 2 +/- 2 +/- 2 +/- 2 +/- 2 Which Station is the Bottleneck? Backlog Example
80
Drum, Buffer & Rope DBR: The generalized process used to manage resources to maximize throughput The Drum is the rate or pace of production set by the system’s constraint. The Buffer is the amount of work in front of the bottleneck resource in order to ensure full utilization, eliminating idle time. Rope is the signal from the bottleneck station to the prior stages/material release to regulate the amount of work flowing to it, in order to maintain a manageable work in process.
81
Drum Buffer Rope The Drum-Buffer-Rope elements
The pace of production, which sets the level of activity for the plant or process Drum Predetermined amount of surplus inventory in front of the constrained resource so that it always has work to do and there is no idle time Buffer It is the signal to release material from the upstream process or station, in keeping with the pace set by the Drum Rope In Theory Of Constraints, the Drum-Buffer-Rope elements represent the following.

86
More of the Same???
87
Or a Refreshing, New Idea?
88
Need for Change Change is a fact of life. Organizations, like organisms, must adapt or die. Neither course is comfortable. In its operations, an organization evolves a way of thinking about itself, its competitors, and the environment with which it and they must cope.
89
Resistance to change Do people resist change?
Resistance to change is the action taken by individuals and groups when they perceive that a change that is occurring as a threat to them. Do people resist change? Or it something else that they resist about change? People resist being changed! People don’t resist change if it is of their liking or if they are involved in making it and feel to be a part of it. Respect for people is a precondition for meaningful and long lasting change.
90
Change Enablers Clarity of Purpose The single most effective motivator
Making adjustment as needed – not being stubborn Persistence Never giving up What works, what doesn’t Asking tough questions Facing challenges Managing conflict to bring out the best Knowledge and Information Invest in learning and sharing Encourage exploration Mutual respect and Trust Non-judgmental Mistakes taken as steps towards improvement
91
Leadership A manager is best when people barely know he exists
Not so good when they obey and acclaim him Worse when they despise him Fail to honor people, they fail to honor you But of a good manager When his job is done, his aim fulfilled They will all say, “We did it ourselves”. Lao Tzu 4000 BC
92
Phases in Learning or Change
1 Unconscious Incompetent I don’t know and I don’t know that I don’t know. Diving? 2 Conscious Incompetent I Don’t know but I know that I don’t know. 3 Conscious Competent I am learning and it shows that I am learning. Bike? 4 Unconscious Competent I am practicing effortlessly. Diving!
93
Phases in Team Work FORM
Team is formed, as in a project, comprising different skills backgrounds. STORM Everyone sees the project from their own perspective, friction and conflict occur NORM Common grounds are found and adjustments are made to achieve the – Risks and Benefits are realized PERFORM Team develops working processes and flows, metrics to track performance
94
Motivation Motivation can be understood not as something that one has but rather as something one does. It involves recognizing a problem, searching for a way to change, and then beginning and sticking with that change strategy. There are, it turns out, many ways to help people move toward such recognition and action. Miller, 1995
