The IETF Administrative Oversight Committee (IAOC), on behalf of the IETF, is seeking one or more vendors to provide software development services. The successful bidder(s) will enter into a contract with the Internet Society. The Internet Society (ISOC) desires to enter into an Indefinite Delivery/Indefinite Quantity (IDIQ) Master Services Agreement (MSA) with one or more software development companies with which to accomplish its objectives. The MSA is an Indefinite Delivery/Indefinite Quantity contract because it cannot be determined at this time the nature and number of applications that will be necessary. The MSA shall be for a three-year period with an option for two, one-year extensions. Through the MSA Work Orders will be issued for the delivery of specified software. The Internet Engineering Task Force (IETF) standards development work is supported by several specialized software tools, such as the Datatracker, idnits, xml2rfc, rfcdiff, and many others. New tools and significant changes to existing tools will be needed, for instance, to support the upcoming change in the RFC publication format. These tools may be developed in Python using the Django framework, or other software if there is a significant advantage or requirement to do so. Being selected for entering into a Master Services Agreement will be a two-step process: 1. Responses to this RFP will be used to identify qualified vendors to proceed to step two; 2. Invited vendors will be asked to provide pricing information for the development of a specific application, including the assumptions and analysis used to reach that price. The purpose of this is to evaluate the analysis and pricing. It may not be used to award the development of this application. The Software Development IDIQ RFP can be found at this location: https://iaoc.ietf.org/rfps.html The Proposal period is open ended. Questions may be submitted at any time. Responses will be published online at https://iaoc.ietf.org/rfps.html within one week of question submission. Proposals and questions are to be sent by email to iaoc-tmc@ietf-bids.org.
