Goal modeling techniques plays a crucial role in requirements engineering since they facilitate the reach of requirements to stakeholders in an understandable easy manner and also in a professional well defined pattern to developers. Modeling of goals are encouraged and proposed during requirements elicitation in order to detail, understand and describe problems associated with current organizational structures and behavior. However, a current challenge appears which is how to manage modeling of goals if either these goals were elicited in early or late phases? Eventually if that occurred the rest of the challenge comes in how to model these goals in the presence of uncertainty? This paper presents a systematic literature review of the current goal modeling techniques dealing with both early and late requirements such as: i* framework, tropos, GRL and UML. The results for research in this study show that although there are models for both early and late requirements, most techniques to a great extent are used for modeling early requirements. The findings lead us to identify two future work elicited in the study that might help a lot in modeling goals.
