In my research of engineering projects under a quality guide in the engineering departments of public organizations, and after determining a number of indicators for the success of the engineering projects, as well as determining the factors of success. After comparison between the measures of success and success factors through A correlation. It turns out that we need to emphasize three factors of success and they are: co-workers, motivation, and the operation of a quality guide. 1. Employee Involvement. Several Local Authority engineers addressed the inclusion of employees in each new procedure, holding a constructive discourse and then writing down an orderly procedure for use. And thus, they succeed in managing the engineering projects. “Every inclusion of employees in every procedure brings about a good result”, so they say [1, p. 73]. A local Authority engineer from Northern Israel says that the involvement of employees brings about success of over 50% in managing engineering projects as they are those who manage the engineering projects and they are those who need to implement the procedures. Occasionally errors in procedures are revealed, but these are corrected instantly [2, p. 14]. Another member of a small Local Authority in the Galilee shares us as well in his method of employee involvement in writing of engineering procedures. He manages the project management system in a computer, to which any employee of the Authority can log in and correct things. However the correction needs to be shared by all, which means that first he makes a certain remark, and then he shares it with the Authority engineer who in turn consults additional employees in the Authority and they decide on an agreed-upon wording. And that employee who has proposed the correction, updates the procedures according to what was agreed.2. Internal Motives: The subject of internal motives has also received much attention from the City engineers whom the study was sent to, although internal motives complements employee involvement on one hand, it bring about immediate results and current activity on the other hand. One of the Authority engineer in the Nazareth region, explains that one of his employees is considered to be the right hand of Authority Mayor, and he assigns him the difficult jobs. “There will always be a positive result” he explains. Another engineer in a medium-size Local Authority explains that upon assuming of position of a new Authority Mayor, he brought along with him a new engineer (project expeditor), that engineer was able occasionally to wrap things up better than the Authority engineer himself, he would close contracts, approve bills and bring about much benefit to expediting of engineering projects. Manager of a constructions division in a large municipality (about 100,000 residents), explains that the subject of internal motive is a very important one and he uses it constantly. There are 15 project expeditors in his team and when he asks one of them to expedite a certain task he employs internal motive. For example, wage increase, or extra hours or another internal motive, and thus he achieves the purpose faster than what was expected [2, p. 26-28]. 3. Quality Management Consultant: The factor of quality manager also constitutes a factor of success in managing engineering projects. The more professional is a project manager, the more effective are the results of engineering projects. In a medium-size Municipality, the quality manager is constantly pointed out and they learn from him continuously, he is constantly pulled from one task to another. “The secret of success of a quality guide lies in him”, they say. The quality manager brings about benefit and industrial peace to all the Authority. He accepts explanations and constraints, he analyzes them and writes down what is good for the system in order to operate properly. In another small Authority, it was stated that the quality manager does not handle all matters of procedures, he neglects what has been asked to improve and thus the quality guide does not reflect what they want. And it is neglected due to this reason.In summary of implementation Indeed, in all Local Authorities that responded to the study, it is indicated that these are indeed the factors that bring about the best results in all matters of managing of quality in management of engineering projects in Local Authorities.
