Proposal of a web application of virtual letters for restaurants as a prevention measure in time of covid-19

The COVID 19 pandemic and the health crisis that today has affected the entire world, has forced many companies to make the use of technological tools essential for them to compete in the market. All this has made mobile applications or web systems the most appropriate solution to implement in your business model. The present investigative work aims to propose the analysis and development of an order management system, digitizing the menu for restaurants and allowing the ordering process to be quick and interactive. Following the guidelines provided by the Government of Peru, in which they recommend, the digitization of traditional letters as it is considered a source of the spread of the coronavirus and to be replaced by menus or virtual letters which can be scanned through QR codes. The development of this project allows customers to view in detail the available dishes offered by the restaurant and proceed to order the food they want, on the other hand, the restaurant can keep track of all orders and relevant information about the business. To develop the prototype, an analysis and information gathering of the technologies to be implemented will begin.


Introduction
Today the use of technologies has spread greatly in the industry, since this represents an opportunity for improvement for any type of business because it enhances the effectiveness of its processes (Jaime et al., 2014).However, (Nhamo et al., 2020) tells us that the pandemic caused by COVID -19 has greatly affected the tourism and gastronomy industries, since these types of businesses are susceptible to natural disasters because they affect the infrastructure and also to any situation that affects human movement, particularly if it is an outbreak of a pandemic such as the one that occurred in 2020. Similarly, it mentions that Ministerial Standard No. 822-2018-MINSA must be complied with, where the "Sanitary Standard for the Operation of Restaurants and Related Services" is ratified, which indicates all the preventive measures that must be taken by both the restaurant and the customer.
Measures that range from complying with the policies of not having contact during the service, disinfection, the use of an application that serves as a means of contact and that the sale is made digitally.It is a way of reinventing themselves that must be chosen by restaurants that have not yet done so (Bernal & Artunduaga, 2020). That is why the performance of delivery applications is of the utmost importance, since due to their characteristics they allow the restaurant to offer a good service and, at the same time, comply with the preventive measures of COVID-19 (Silipo et al., 2020).
Likewise, customer demand is increasing, so it is necessary for restaurants to opt for this type of solutions to return to the market and be competitive with the rest, he mentions (Nhamo, Dube, Chikodzi, 2020). Therefore, it can be said that from now on the new normal radically changed the traditional business model in restaurants. Encouraging the implementation and use of new digital tools in your business process.
That is why, through this article, the purpose of this article is to identify the incidence generated by the use of this digital tool in restaurants as a preventive measure in contact with the pandemic that we are experiencing.
Also, this article will explain the technical terms for the design, Nowadays organizations, due to the contextual situation, have found it necessary to reinvent their business so that it can cope with the health crisis and for this they must adapt to all safety protocols, respecting health regulations. Therefore, companies have increasingly made use of technological tools, in which through innovative proposals they can adapt their businesses, so that they benefit their customers and can continue as they previously carried out their activities with greater profits.
Research question statement: How will the proposal to implement a virtual menu web application for restaurants have an impact as a preventive measure in times of covid-19? Developing a prototype of a web application that replaces the conventional menus or menus of restaurants, supported by the opinions of end users to obtain a product in which information on the dishes offered is known, investigated and interacted with.
-Investigate the impact of the web application regarding the reduction of contact between people within the restaurant as a preventive measure against COVID -19.
-A virtual menu will help restaurants to cope with the health crisis that is being experienced in order to comply with the measures implemented by the Government.
-Identify the appropriate tools to develop the web application complying with the necessary requirements and making it understandable for all types of audiences. -Deliver a web application that allows diners to have more detailed information about each dish that will be offered within the restaurant.

Methodology
The type of research of this project is applied with a descriptive design, which aims to specify the impact of the implementation of a virtual menu system for restaurants.
For software development, the XP methodology was used as a basis, which is an agile software development methodology developed by Kent Beck in 1996, which is based on a set of values that guide development.
This methodology is based on the values of simplicity, communication, feedback and value. XP greatly seeks customer satisfaction (Anwer et al., 2017).
Prototype development: It can be considered as that process of development of a device or system that reveals the viability of a treatment proposal to a problem.
Typically, prototypes are handled only by their designers or by those who understand their underlying technology (Reiser and Anbar, 1984).
The conception takes place on a prototype, in other words, a model or the trial version of the product. Later, after different iterations, the prototype is improved and refined into the finished product (Thomas, 1993).

Balsamiq Mockups:
It is a program in which you can design all kinds ofprototypes and sketches that will be useful for the development of a project that is as close as possible to our designed prototype. Likewise, the easy-to-use interface allows you to select between different predesigned models: status bars, menus, progress bars, among others.
Extreme Programming (XP): XP consists of a series of activities, also called life cycle, which is displayed below: The phases of the XP Methodology are described below.
-Planning, in this phase the system requirements are identified. -Design, in this phase it is explained how the sketch will be, it is not necessary to show the structure or functionalities. -Coding, in this phase the completion of the pending activities for the elaboration of the system is detailed taking into account the user's requirements. -checkIn this phase, those activities prior to implementation are verified. Unit tests must pass tests before being implemented. There are also the acceptance tests, which consists of the deliverables satisfying the previously agreed upon user requirements.   3 -Would you be willing to share your information about your tastes and preferences in a virtual letter web application?
