SCES ‘21 is a dual-mode summit meeting where leaders in the field of software cost estimation from industry, government and research share their insights and experience in forecasting the cost and other resources needed to complete a software intensive project within a defined scope. Since almost everything developed or constructed today involves a significant software component, software cost estimation is becoming increasingly important.

SCES ‘21 will be held on November 9 and 10. The physical part of this summit will take place in the beautiful Philharmonie in Haarlem (the Netherlands), where you can connect physically with the speakers and fellow software cost estimation professionals. Since COVID restrictions limit the number of people that can safely be brought together, most of the summit will be also available online. In this way anyone who is not able to join this summit or does not feel comfortable to travel to the Netherlands can still share in the insights and experiences that will be shared.

In the event that a visitor to the Summit is not allowed to travel to the Netherlands in the period of 6-11 November 2021 according to travel restrictions from the Dutch government, the price of the ticket will be refunded upon request.

The corona rules changed in the Netherlands from September 25. The good news is that 280 people can attend the Software Cost Estimation Summit in theatre the Philharmonie in Haarlem but that also means that the theater has to take the following measures for who will attend the summit: Philharmonie

  • Attendees must show a valid identification (e.g. passport)
  • Attendees must have a corona check app with a QR Code to show that they are vaccinated or recently tested (PCR, Antigen)
  • A self-test is not valid to enter the theater

 These rules apply to everyone who will attend the theater including presenters and organization.

The organization of the SCES ’21 will follow the governance rules to keep the event save for all attendees.

Call for participation

Estimating software development effort is an essential part of getting new or improved software products to its intended end-users. An cost and effort estimate sets the expectations of the end-users as to when the software will be ready and what it will cost. Multiple sources show that estimating software development cost and effort has a bad track-record, despite over fourty years of research on good software cost estimating practices. The Software Cost Estimation Summit is devoted to promote experiences on good software cost estimation practices. To stimulate the use of good cost estimating practices, the summit is now challenging cost estimation practitioners to show their competence in estimating software development cost.

Estimating the cost of software development is intellectually stimulating
and challenging and worth winning an international award!

The aim of this challenge is to provide a rigorous interactive session in software cost estimation presentations by the participating teams on a realistic case study, with the added benefits of cross-learning from teams and insights from a professional expert panel.

The challenge is open

  • To practitioner teams from private and public organizations.
  • Who will be provided with a Case Study with a high-level set of software requirements.
  • Four weeks ahead of the Summit.
  • To present their Cost Estimation solution at the Summit by the team captain.

A professional expert panel will decide which team wins the challenge. Deciding criteria will be:

  • The use of standardized methods to translate requirements to cost
  • Methods to prove the reliability of the cost estimate
  • The use of experience data to substantiate the cost estimate
  • A standardized approach to account for incompleteness of the requirements

Register your team no later than september 30th, 2021 by sending an e-mail to The registration should contain:

  • The name of your team
  • The name and residing country of your organization
  • The names of the team members
  • The contact data (e-mail and phone number) of the team captain
