Which design pattern that can be used in integration module?

I am working on an integration module and all the integration code is written in only one class from where I am accessing all the module services. Is there any design pattern that can be used for integration modules or integration classes?

My integration java class contains one method like below:

executeProcess() {

    moduleservice1();

    moduleservice2();

    moduleservice3();

    moduleservice4();
}

Thanks for your help in advance.
