Outsourcing is usually used to reduce the costs of the company. Additionally, it adds specific expertise needed for a product or service without the requirement to invest more in in-house experts.

Now that we reviewed outsourcing, let’s now discuss what multiple sourcing is. Multiple sourcing or multi-sourcing is a type of outsourcing that is used by numerous companies.

Unlike traditional sourcing which deals with a single vendor, multi-sourcing makes use of numerous different vendors.

Typically, A company will handle some of the IT operations and outsource the rest of the other duties. The idea behind multi-sourcing is to make IT operations more effective in the process.

Through multiple-sourcing, a company can select the best possible vendor for a given IT task. By outsourcing other operations, the company can focus more on its most important duties internally.

When a company chooses the multiple sourcing approach, it must ensure that an in-house employee is monitoring the vendors. One of the best ways to find vendors is that you have a similar corporate culture.

What is Single Sourcing?

Single sourcing is a practice where you can select one supplier out of the numerous ones. The suppliers that you select provide the same products or services. Your requirements will determine who among the suppliers will suit your company best.

The company may also choose based on what it thinks it needs. It may choose the other as it has lower prices than the rest of the suppliers.

HowDoes Multi-Sourcing Work?

In many companies, the IT vendor management office takes charge of managing multiple sourcing arrangements with help from the legal team, IT staff, and other executives. To begin, it’s wise to choose service delivery providers that share similar corporate cultures.

Moreover, organizations adopting multiple sourcing should establish strong internal corporate governance strategies for IT vendor relationships and share these details with all service providers. This helps improve cooperation and ensures smoother service delivery throughout the organization.

Why You Should UseMulti-Sourcing

Multiple sourcing is a procurement strategy embraced by companies, which involves obtaining goods or services from multiple suppliers rather than depending solely on a single source. This strategic approach offers numerous advantages that contribute to the overall efficiency and success of a business.

One of the major benefits of multiple sourcing is cost reduction. Engaging with multiple suppliers enables companies to tap into a competitive environment where suppliers vie for the business by offering more favorable pricing and terms. As a result, the company can negotiate better deals, leading to significant cost savings and improved financial performance.

Enhanced quality assurance is another compelling advantage of multiple sourcing. Different suppliers may adhere to varying quality standards and production processes. By sourcing from multiple suppliers, companies can carefully assess and compare the quality of products or services, ensuring they opt for the best options available.

Furthermore, multiple sourcing provides a buffer against potential risks and disruptions. Relying solely on a single supplier can leave a company vulnerable to supply chain disruptions caused by various factors, such as natural disasters or economic downturns. However, by diversifying their sources, companies spread their risks, making them more resilient and capable of navigating unforeseen challenges effectively.

Using Multi-Sourcingin Procurement

Multiple sourcing in procurement involves acquiring goods or services from different suppliers, which can save costs and improve product quality.

To implement multiple sourcing effectively in procurement, consider your needs and what each supplier offers. Use clear contracts to specify suppliers’ roles and contributions to costs. Regularly assess suppliers’ performance to ensure they meet your expectations.

Maintaining strong communication and backup plans is essential. Building good relationships with suppliers and having alternative options ready can lead to better outcomes and smoother operations.

Advantagesof Multi-Sourcing

Multiple sourcing can benefit businesses that spread their demand across different suppliers. This is also necessary when a supplier cannot meet the total requirements of the organization. 

Common advantages of multi-sourcing include:

1. Reduced reliance on a single supplier

By engaging multiple suppliers, a company becomes less vulnerable to potential difficulties or disruptions that could arise from unforeseen events impacting a single supplier. This diversification ensures a continuous supply of goods or services even if one supplier faces challenges.

2. Improved flexibility

Multiple sourcing provides companies with the flexibility to adapt to uncertain events that may disrupt the capacity or supply of goods and services. Having alternative suppliers enables quick adjustments to changing market conditions, safeguarding against potential bottlenecks in the supply chain.

3. Reduced bottlenecks

Relying on a single supplier can lead to bottlenecks when the supplier’s capacity cannot meet the demand. Engaging more suppliers ensures a more efficient distribution of orders, preventing delays and ensuring a smooth flow of goods or services.

4. Enhanced supplier competition

With multiple suppliers vying for business, healthy competition emerges. This competition incentivizes suppliers to enhance their cost-effectiveness and service quality to attract and retain clients, benefiting the company with improved offerings.

5. Improved bargaining power

The competition among suppliers enables the company with greater bargaining power. With multiple options available, the company can negotiate better terms and prices, leading to cost savings and improved contractual conditions.

6. Easier access to higher product and service quality

A diverse pool of suppliers provides the company with a broader range of options, allowing them to choose suppliers renowned for high-quality products or services. This enhances the overall quality of the goods or services offered by the company to its customers.

These may include product quality, delivery capabilities, customer reviews, supplier performance history, diversity aspects, and other relevant factors.

By identifying potential risks associated with suppliers, such as breaches of contract, late deliveries, quality issues, or financial instability, the company can implement risk mitigation strategies to avoid any unexpected disruptions.
