Approach & Schedule, Stage 1: Supplier Pre-Qualification No.

Step

1.

Demand Analysis Work with Client to define and understand the products and requirements (volumes, materials, production technology requirements, Quality tests, Standards, etc.)

• Kick-Off Report

2.

Supply Market Analysis Identify long list of potential suppliers in the selected markets (China & India) by leveraging B2B Websites, DS Database, Fair catalogues, Chamber of Commerce, Magazines, Network, References.

• Supplier Long List

3.

Telephone Pre-screening Selection of suppliers to be included in the RFI process by telephone pre-screening based on agreed simple criteria (e.g. capability to make the product, Minimum company size, quality certifications, interest in participating, Export capability etc to be defined by Client).

• Shortlist for RFI process

4.

Develop RFI document Prepare an RFI template, with an aligned Balanced Scorecard that has the objective to pre-qualify the capabilities of the suppliers, including: Background, financial, Client and product experience, Quality certification & processes, Social Responsibility, Manufacturing/technology capability)

• RFI Template • Balanced Scorecard

5.

Conduct RFI Administration The RFI is translated to the local languages as relevant, and distributed to the relevant suppliers, with telephone follow-up to push for maximum participation.

• Completed RFI’s

6.

Analyze RFI Responses Analysis of RFI responses and preparation of a report which profiles & objectively ranks the suppliers by capability including a recommendation for those to be audited.

• RFI Report • Supplier Profiles • Proposed Shortlist for Audit.

Result & Recommendation Results

Recommendation

❑ Whole project is carried out in 9 weeks with total 127 suppliers identified in China and India.

DS recommend 11 suppliers for next step, • China: 7 • India : 4

• Total 14 RFI’s received from 21 suppliers passed in pre-screening process.

• Information about rejection during pre screening process & RFI rejection by suppliers are given in the report.

•

1. NDA Process with shortlisted suppliers 2. RFQ process with NDA responders

❑ The top RFI ranking are the Chinese suppliers able to offer dimensions as per Client requirement. ❑ Indian suppliers have limitations on the maximum diameter and weightage to offer. ❑ Nearly all the suppliers are ISO 9001 certified except two Indian suppliers with lowest ranking and most of them are also certified with ISO 14001. © 2019 Dragon Sourcing.
