    If you choose to buy electronic equipment, its disadvantages are: 1) high initial cost; 2) limited functions; 3) limited compatibility with existing systems. However, the advantages are 1) faster implementation, 2) support from vendors, and 3) universal software. The advantages of building custom software are: 1) customization for the business; 2) stronger scalability; 3) different from competitors. The disadvantages are 1) the time to build, 2) also need to pay upfront costs, and 3) the software may malfunction during the development process.

    Advantages: It can not only eliminate the trouble of data transmission through tape and floppy disk, but also make the data transmission immediately, so the data itself can arrive in real time.
    Disadvantages: There is no precedent and no industry benchmark, the ready-made products bought in the open market are expensive, there are compatibility problems with the existing system, need to be customized, high cost and long research and development time.

    Advantages:
    At mudra, ES aims to provide managers and leaders of the organization with real-time data so that they can take timely action to ensure business profitability.
    Network oriented ES is a logical way forward, because it can not only eliminate the trouble of data transmission through tape and floppy disk, but also make the data transmission immediately, so the data itself will arrive in real time.
    A high degree of customized development (internal es to meet the needs of customers (advertisers and media), even in normal times).
    The development of ES system, contrary to the choice of purchase, people can purchase an integrated package from the shelf and customize it – the construction route promotes the modular method in essence. Since each component can be built and tested separately before final integration, it provides flexibility for the design and development process, which is a valuable advantage.

    Disadvantages:
    The task of launching es also needs to work hand in hand with employees. companies need trainers who understand both the new system and the old system. They must also be internal and have a strong it orientation; however, If the internal IT resources composed of a large number of full-time employees are not only limited, but also stretched.

    benefits (“pros”) and risks (“cons”) of a buy:

    pros:The ES Package is developed in standard mode. After repeated debugging, it has been widely used and its quality is guaranteed. The purchase of commercial software can speed up the development progress of information system.

    cons: Standardized software can greatly promote the transformation of the organization, especially the process, which brings difficulties and risks to the success of the enterprise.

    benefits (“pros”) and risks (“cons”) of a build:

    pros; The ES package design can be carried out according to the business characteristics and management functions of the enterprise itself, which can effectively avoid the complex setting and configuration functions in the general software, and is most close to the actual business and simple to use. Also The ES package design can be carried out according to the business characteristics and management functions of the enterprise itself, which can effectively avoid the complex setting and configuration functions in the general software, and is most close to the actual business and simple to use.

    Cons: Develop the ES package by yourself and work on other aspects, the implementation cycle will be longer.Thus, not only the cost of software development must be considered, but also the opportunity cost of delaying the implementation of the ES Package.
