Conclusion: Summarizing the End-to-End Supply Chain
1. Understanding the Basics of a Supply Chain
Definition and Importance
You want your supply chain to run smoothly, efficiently, and profitably from raw materials to final delivery. That involves a complex network of interconnected plan-make-move-buy decisions that impact cost, efficiency, customer satisfaction, and ultimately, EBITDA. How can you ensure that all parts are in alignment?
The more you understand the supply chain, the better you can manage it.
Key Components of a Supply Chain
The key components of a supply chain include:
- Suppliers: They provide a product or service to your business, from raw materials and finished goods to advice and transportation.
- Manufacturers/Producers: They convert the raw materials into finished goods.
- Distributors: They store, transport, and deliver goods to the next link in the chain.
- Retailers: They sell the final product to consumers.
- Customers: The end-users who consume the product or service.
Types of Supply Chains
The type of supply chain your company is involved in depends on your company’s various roles as supplier, producer, distributor, retailer, and/or customer; your company is likely engaged in more than one type:
- Direct Supply Chain: Are you a retailer? You sell directly to customers, without the use of intermediaries.
- Indirect Supply Chain: Are you a wholesaler, distributer, or retailer in someone else’s supply chain?
- Reverse Supply Chain: Do you recycle, dispose of, or resell your own products or those of others?
- Global Supply Chain: Does your supply chain encompass international suppliers, manufacturers, and customers? This type of supply chain can be much more complex due to the need to navigate different laws, customs processes, and shipping methods across borders.
A healthy supply chain is flexible, adaptable, and customer-focused. Its strength lies in data-driven insights that enable you to manage supply chain risks, seize opportunities, and improve performance and customer satisfaction.
2. Planning in Supply Chain
When your demand forecasting is accurate, it reduces the risk of either stock-outs (which result in lost sales) or overstock (which increases storage and potential wastage costs). But accurately forecasting consumer demand, as crucial as it is to supply chain planning, is difficult unless you have sales data, market research, statistical algorithms, and a process for gathering data that you trust.
Product, design, program, and operations excellence contribute to accurate and resilient supply planning that:
- Aligns production schedules with demand
- Reduces inventory costs and wastage
- Ensures products are available when needed.
Supply planning requires collaboration with suppliers, which may not come naturally to your organization.
Sales, Inventory, and Operations Planning (SIOP)
A strong SIOP process that is clearly defined and broadly understood adds value to your company and helps it withstand market turbulence. SIOP provides a strategic direction for all the functions in your company and ensures that the organization works towards a common set of goals and matches management’s appetite for risk.
3. Sourcing and Procurement
Supplier Selection and Management
Some companies feel trapped in unfavorable contracts; worried about their future if a key supplier fails or changes loyalties; or unclear about their options. If this sounds familiar, you do have options.
- Supplier optionality brings new sources into your supply chain and reduces risk by considering location, quality, cost, reliability, financial health, delivery times, and many other key factors during supplier selection.
- Supplier performance management begins with transparency and clarity about requirements, including performance criteria. It establishes a mutually beneficial relationship.
A mature procurement department holds regular informational meetings with suppliers and conducts regular performance reviews. The quality of your supplier selection and management helps determine if you enter contract negotiations in a win-win environment.
Strategic sourcing goes beyond traditional, transactional purchasing. It is a systematic and fact-based approach for optimizing your company’s supply base and improving the overall value proposition.
A thorough analysis of spend, demand, and supply will put you on the road to an optimized strategy. Strategic sourcing is executed through a structured RFQ, RFP, or RFI process; contract negotiations; ongoing supplier performance management; and other initiatives.
Procurement Best Practices
Has your procurement become an equal partner in sales, inventory, and operations planning (SIOP) or is it still considered transactional?
A procurement department that operates at a high level of maturity has strong supplier relationships; continually reviews procurement policies and applies them consistently; and adapts a strategic sourcing approach, aware that upstream decisions have consequences downstream and vice versa.
4. Production and Manufacturing
Network Design and Footprint Optimization
With footprint optimization, your production and manufacturing processes become more efficient, productive, and safe while generating less waste. With greater efficiency and improved asset utilization, you will be able to deliver more with fewer resources. While Lean manufacturing is one methodology, there are many other steps you can take to improve efficiency, quality, and agility in the supply chain.
Network optimization and design includes route and last mile delivery optimization, fleet management, and make vs. buy decisions that also affect the resilience of your supply chain.
Quality Assurance and Control
Quality assurance and control ensure that specifications are met all along the plan-make-buy-move supply chain, so that a quality product or service is delivered. A quality management system (QMS) can provide a structured framework for continuous improvement, helping your company to meet and exceed customer expectations.
5. Logistics and Distribution
One of the principles of supply chain optimization is that upstream decisions affect downstream productivity and vice versa. All too often, shortcomings in order fulfillment are blamed on poor warehouse management when their true source is further upstream.
For example, if a warehouse must receive items in a timely matter to ensure safe and efficient storage and retrieval of items, which in turn directly impacts order fulfillment times and customer satisfaction.
Inventory management is a major component of warehousing and inventory control, forecasting, replenishment, and demand management of both raw materials (components) and finished goods (products).
Are your raw materials arriving on-time in-full (OTIF)? Are you making items you would be better off buying? Is your inventory filled with obsolete products that customers no longer want? Inventory management requires a systematic approach to sourcing, storing, and selling.
Transportation Modes and Management
Whether you transport by road, rail, sea, or air, logistics optimization and transportation management can reduce delivery timelines, overages, and costs. Transportation management involves overseeing the movement of goods from origin to destination, including route planning, carrier selection, freight auditing, and tracking of shipments.
The mode of transportation you choose depends on decisions made earlier in the supply chain. For example:
- What are the benefits of proximity to suppliers versus proximity to customers?
- Are your carbon emissions in line with regulations or is a change in transportation mode warranted?
- Are you prepared to deal with tariffs, cross-border differences in regulations, and 3PL or 4PL suppliers, among other factors influencing your choice of transport?
Last Mile Delivery
The "last mile" of delivery refers to the movement of a product from the warehouse to the customer’s doorstep. This is often the most complex and costly part of the logistics chain because it involves multiple stops with small deliveries. You might improve the efficiency of your last-mile delivery through route optimization, the use of 3PL or 4PL suppliers, and leveraging technology for tracking and communication.
6. Waste Management
Environmental considerations and regulations exert strong pressure for waste management and recycling. Your company and your suppliers—and your suppliers’ suppliers—all have responsibilities under the Greenhouse Gas Protocol to minimize waste.
Scope 3 of the Greenhouse Gas Protocol covers the carbon generated by the purchase, use, and disposal of products that you buy from suppliers. It also expects you to take some responsibility for how your customers manage the lifetime use and disposal of your products and their packaging.
Reverse logistics come into play when your customer returns products, a process that should be easy and seamless but should not affect your profitability. Whether you ultimately decide to recycle, refurbish, or resell returns, the preferred approach is to prevent returns in the first place.
Reducing order cancellations and returns may involve initiatives in:
- Supply planning
- Supplier performance management
- SIOP processes
- Spend management
- Last mile delivery
- Fleet optimization.
You may choose to resell or recycle raw materials or finished products or dispose of them in a way that reduces the environmental impact. However, the earlier that waste reduction occurs in the supply chain, the less waste is generated later on. Waste reduction is yet another benefit from improvements in:
- The design and packaging of materials
- Supply and demand forecasting
- Inventory management
- Quality assurance.
7. Supply Chain Technologies
Advantages of Technology
Technology enables your company to improve efficiency and transparency and reduce costs.
- A major mining company halted a 1 year slide in its schedule by tracking asset availability and utilization and people availability for the first time
- An organization gained insight into members’ buying behavior and its own spend by using AI to convert data from 40 GB of invoices into structured fields
- A master resource schedule, SIOP reports, and vision boards gave a manufacturer a 240% productivity improvement and $8.8 annualized benefits to P&L.
Enterprise Resource Planning (ERP)
If you need to integrate business processes and functions, ERP systems will bring together data from procurement, inventory, operations, sales, and finance. Priming your ERP with KPIs that align with company goals and then properly mining the data provides insight into your entire plan-make-buy-move supply chain.
Supply Chain Management Software (SCM)
If you need more visibility into the movement of a product or service, SCM systems bring efficiency and clarity to supply chain planning, execution, and collaboration; supplier relationship management; and order management.
AI and Machine Learning in Supply Chain
Artificial intelligence (AI) in the supply chain and machine learning technologies analyze large amounts of data, uncover patterns, and make predictions. Applications can include demand forecasting, inventory optimization, logistics routing, and predictive maintenance for equipment. While they improve accuracy and efficiency, they also require significant investment and expertise to implement effectively.
8. Risk Management in Supply Chain
Identifying and Evaluating Risks
What types of risks worry you?
- Length and potential disruption of your supply chain
- Transport delays and distance from customers
- Supplier failures due to economic, political, or natural disasters
- Quality failures
- Regulatory changes
- Demand variability and consumer pivots
- Geographic and capacity constraints
- Equipment failures and poor utilization
- Post-merger or post-acquisition integration.
Once risks are identified, they should be evaluated based on their potential impact and the likelihood of occurrence.
Strategies for Risk Mitigation
Risk mitigation strategies might include diversifying suppliers to reduce dependency on a single source, maintaining safety stock to guard against demand or supply volatility, implementing robust quality checks to minimize the risk of product defects, or operational due diligence. The optimal strategies will depend on your risk profile and business context.
Disaster Recovery and Business Continuity
Despite the best mitigation strategies, some disruptions may be inevitable. In these cases, having a robust disaster recovery and business continuity plan is critical. This plan should outline the steps to be taken to recover operations quickly and effectively in the event of a disruption. It could include backup plans for critical operations, emergency response procedures, and communication plans to keep all stakeholders informed.
9. Sustainable Supply Chain Management
Importance of Sustainability
Sustainability in the supply chain encompasses long-term environmental, social, and economic impacts on people, the planet, and profitability. Sustainable supply chains are becoming increasingly important due to regulatory pressures, consumer expectations, and the recognition that sustainable practices can also improve efficiency and reputation.
Green Supply Chain Practices
Green supply chain practices include efforts to reduce energy consumption, minimize waste and emissions, improve recycling and reuse, and reduce the overall environmental footprint of supply chain activities. These practices include changes in product design, materials sourcing, manufacturing processes, logistics, and end-of-life product management.
Social Responsibility in the Supply Chain
Social responsibility in the supply chain begins with fair labor practices, promoting health and safety, supporting diversity and inclusion, and contributing positively to the communities where the business operates. To encourage social responsibility, you should set clear standards for suppliers, conduct audits, and engage in initiatives to support local development.
You achieve economic sustainability when your supply chain activities contribute to long-term economic success, not just short-term profits. Investments in technologies, improvements in efficiency and resilience, strong relationships with suppliers and customers, and considering the full life-cycle costs and benefits of products are all practices that build economic sustainability.
10. Supply Chain Analytics
The Role of Analytics in Supply Chain Management
The amount of data available to a company increases every year. It is time to ask:
- How much trust do I put in the data I receive?
- How easy is the data to understand and format?
- Where is the data coming from?
- Is there additional data we should have but don’t?
- Is the data sufficient for planning and decision making?
- Do we make data-driven decisions or intuitive ones?
- How current is our data?
- Is it timely enough for demand forecasting, logistics optimization, and other time-sensitive functions?
- Is our data able to identify patterns and trends and predict future scenarios?
Types of Supply Chain Analytics
There are four primary types of analytics used in the supply chain:
- Descriptive Analytics: This involves analyzing historical data to understand what has happened in the past.
- Diagnostic Analytics: This is focused on understanding why something happened in the past.
- Predictive Analytics: These are techniques used to forecast future events based on historical data.
- Prescriptive Analytics: This is the use of models to suggest the best course of action among different alternatives.
Implementing Supply Chain Analytics
Implementing supply chain analytics involves setting clear objectives, gathering and cleaning the necessary data, selecting the appropriate analytical methods, and building the capabilities to interpret and act on the analytical insights. This often requires investment in technology and skills, as well as a culture that values data-driven decision making. The goal of supply chain analytics is not just to produce interesting insights, but to drive better decisions and outcomes.
