A review of orbit improvement for spectroscopic and eclipsing binary stars is presented. Specifically, capabilities for orbital and line profile analyses of these systems using the KOREL disentangling program (Hadrava 1995; 1997) are discussed. After a short literature review, criteria and possible paths for orbital improvement are presented, namely a procedure for including visual data in a disentangling solution, along with possible optimization algorithms. A solution ``template'', based on the study of V578 Mon by Hensberge et al. (2000), is presented. Analyses of specific systems are presented, showing explicitly how disentangling has resulted in improved orbits and a better general understanding of each system. Comparisons with more traditional methods such as cross - correlation are made for this purpose.
