Preparations must be made first Issues such as company processes, consultancy requirements, growth perspective, and employee participation should be evaluated.Past projects and lessons learned from experienced users should be discussed and the expectation clarified for each department.Points that waste time, decrease competitiveness.enhancing practices and long-unquestioned habits should form the basis of the search for software. Many terms are used for the area we serve.While terms such as ERP, chain store management or retail information system may be sufficient for corporate companies, smaller businesses often use expressions such as barcode system, barcode automation, store automation or store system.In fact, regardless of its size, every company benefits from innovations to the extent of its capacity. Traditional purchasing method - Product selection Software purchases can be made by determining fixed content, fixed cost and fixed project duration.The reason for the existence of this method, which is the most well-known and applied in the market, is that it is close to the habits in purchasing goods and does not take into account the features of the traditional product purchasing method that are not compatible with software purchasing. When deciding to buy a car, what to expect, price-performance relationship, usage area, maintenance information, driver information.Many issues, such as driver's license, are extremely clear and known to everyone.Considering the fact that software is not a tangible product, the fact that service is always a part of the business in commercial software, the competence of the IT department, and the needs to operate and update the software, it becomes clear how different it is from buying a car.It is coming out. The widespread use and ease of use of products based on consumer technology enable managers who are curious about technology to consider themselves competent in software selection, and may cause illusions when it comes to consulting experts or relevant employees. When we act with the assumption that the size of the company, business processes and technological development will remain constant, the result isIt will most likely fail. Custom software project method - Company selection In this method, purchasing is carried out with a flexible content, according to the analysis of flexible project duration and cost and company-specific processes.The company receiving the service is very knowledgeable about its subject and the process;It is assumed that he can give his recipes in the best possible way.Considering that all critical points are transferred to the software company, it is very difficult for the system obtained as a result of development and adaptation to provide the necessary solutions permanently.Although it has significant advantages over the product selection method with its flexibility in time and cost, the parties managing the project must have the highest level of knowledge of the relevant software product and company.The focus is on fulfilling all of the customer's wishes rather than searching for the truth. Consulting method - Business partner selection When purchasing is done through consultancy, the management of all steps related to the project, such as project management, analysis of company processes, and deciding on the necessary software development steps, are carried out together with the relevant company.Since mutual trust is extremely important, it is very difficult to find the chance to progress with this method.It is essential to work in an environment of continuous improvement without reducing efficiency. The key issue in this method is that the point to receive service is not structured like a pure software company, it is specialized in business processes, It is always focused on improvement in favor of the customer.With the appropriate project plan and cost structure, the software company acts with the mentality of managing its own business and always stays ahead of the users, being alert to points that create inefficiency and meeting their needs.eyes and comments at their best.It does not accept requests as they are, always questions the underlying sources of the requests, and the real automation needs are described together. Taking into account the company's capacity to absorb innovations, a phased project approach is created instead of a single block.After the basic transition is achieved, appropriate modules are put into operation.In the timing of this, trust is again felt in the company from which the service is received.
