What are the specific advantage

Answer
The external team can draw a wealth of experience from having worked with different types of organizations that have had the same or similar types of problems .this wide range of experience would enable them to think both divergence and convergence (分歧与融合）rather than coming to a solution immediately on the basis of the apparent facts in the situation .they would be able to think of several alternative ways of looking at the problem because of their situations .having looked at the situation from several possible angles and viewpoints ,they would then critically assess each of these ,eliminate（除去） the less viable options and alternatives and focus on selected feasible（可行的） soulutions.
The external teams especially those from established research and consulting firms might have greater knowledge of current sophisticated /sefitificid/（复杂的）problem solving models through their periodic(周期的） training programs which may or may not be the case with the teams within the organization .because knowledge obsolescenceis（退化） a real threat （威胁）in the consulting area ,external research institutions （体系）ensure that their members are current on the latest innovations through organized training programs .the extent to which internal team members are kept abreast （并驾齐驱，了解最新情况） of the latest problem solving techniques may vary considerably from organization to organization .

Question 2
How can a good literature survey help the researcher in problem solving ?

Answer :
A good literature survey thus provides the foundation for developing a comprehensive theoretical framework from which hypotheses can be developed for testing
A good literature survey thus ensure that :
Important variables that are likely to influence the problem situation are not left out the study
A clearer idea emerges (浮现）as to what variables would be most important to consider ,why they would be considered important and how they should be investigated to solve the problem .thus ,literature survey helps the development of the theoretical framework and hypotheses for testing
testability and repeatability of the findings of the current research are enhanced .
