Conclusion

• We at Brainpool have found that the Erlang
  System/OTP is a reliable and usable platform.
• We look forward to working with Erlang in the
  future, as well as increasing our cooperation
  with Ericsson.
• We intend to train a larger group of consultants
  in Erlang to meet this goal.
