Question 2

IBM or International Business Machines has its own internal IT team. And if anyone works with the system analyst what will be the result?

SDLC

SDLC stands for software development life cycle. It actually helps analysts to test and design the high level priority software’s. Sdlc should be under in any organization. It has a method to enhance the quality of software. There are many stages in sdlc. The first one is planning and the second one is deployment, the third one is testing, the fourth one is building, the fifth one is defining and the sixth one is designing. Sdlc follows this stages are-

Stage 1: Analysis of planning and requirement

Requirement analysis is an essential part of the software development life cycle. This is one of the fundamental stages. It is executed by the superior members and takes input by the customers (Li et al. 2018). It helps in technical areas and other researchable areas. By the Department of Sales and the surveys of market and domain members of the company, It is performed. This data helps to plan the project and manage other products in the economic and technological areas.

Plan for the quality control required and identifies the possibility with the material is also done at the stage of the plan. It actually helps to implement the project. It has many technical procedures.

Stage 2: Requirements defining

Defining requirements is one of the essential parts after planning and requirement analysis. It actually helps to define the project. Defining requirements is the most essential part in a software development life cycle (Loo and Mahdavinejad, 2018). AFter requirement analysis is done, the next point is requirements of the customers and it depends on market analysis. This project can be done by srs or software requirement specification. It actually helps to plan the project life cycle. It actually helps to include product requirements.

Stage 3: Designing the product architecture

After defining requirements, designing and product architecture is one of the most important architectures in the software development life cycle. Sirs is the recommendation of the product architectures. For the best architecture developing srs is necessary. It helps to propose the architecture. it helps to implement the document specification.The dds actually helps to make the assessment and also the product robustness. For the design modularity and the time constraints that are pointed to the products.

Stage 4: Product developing or building

After designing the product architecture, building or developing the product is one of the most essential parts in the software development life cycle (Lu et al. 2019). Software development life cycle actually helps to begin the development. Hence, For product building sdlc is must. After that, programming could bring about the stage of DDS. If the plan is handled in a detailed manner, the generation of code is skilled without much effort.

“Stage 5:product testing

After building or developing the product, testing products is one of the most important parts in software development life cycle or SDLC. This stage only helps to test the products of faults, retested etc (Lu et al. 2019). Until the outcome gets higher standards, hence It is defined by srs.

Stage 6:Deployment in the market

After testing the product, deployment in the market is the one of the most essential parts in the software development life cycle or SDLC. After the outcome of the productivity is tested and ready to get released in the market. Hence, the outcome of the products disclosed and maintenance is done at the deployment in the market and maintenance (Lukosch et al. 2018). Hence this is the deployment in the market and maintenance.

Question 3

Development methodology of agile software

In SDLC, There are various kinds of SDLC models and methodologies in the software development life cycle (Luo et al. 2018). It actually needs an IT company to deliver these methodologies. Then various kinds of methodologies are needed to make a project.

1.Development methodology of Agile software

Agile methodology is completely different from the waterfall model. It follows the SDLC method. It does not actually follow the SDLC method consecutively. It actually goes along with incremental development and it makes all the changes. At every step this methodology needs more cooperation (Machnoor et al. 2018). This agile methodology has many advantages and disadvantages also in the software development life cycle. The work is split before making the next step in SDLC.

Advantages

  1. The first transportation of the working assignment
  2. significance of the cooperation of all involved in the assignment
  3. Direct connections based on inputs.

Figure 3: The agile model

Disadvantages

  1. used for only small businesses
  2. documents have to be finished at after stages
  3. high dependence for the customer

2.Development methodology of waterfall software”

Waterfall methodology is completely different from agile methodology. Waterfall methodology should go along without any interruptions. It has inflexible structures. After that, it also has particular procedures (Magana et al. 2018). This methodology also needs requirement and maintenance. In waterfall methodology, demand needs to be introduced and the next step should be followed. After that all the assignments should begin with the starting period.

It also has agencies like government sectors.

Advantages

  1. This methodology is not very hard to understand.
  2. This methodology follows organized procedure

3.Well explained the stages that make the assignment very good in advance.

Figure 4: SDLC waterfall model

(Source: https://www.softwaretestinghelp.com/wp-content/qa/uploads/2019/09/SDLC-Waterfall-Model.png)

Disadvantages

  1. Very accurate and rigid process
  2. At first we have to clear the first process then the second one will start.
  3. inflexible and high-pricing methodology

Agile

waterfall

Development in low sprints.

Develop in predefined phrases

Agile must be tensile and also has the alterable methods

The process should be in documents and follow the starting of the process

There should be a future of direction that develops a process

First we have to check the quality and then the requirements

There also has the iterative evolution process

When agreed, the required things are final

In SDLC there are also planning and requirements to grow.

There should be one function group and also has another phase from their job burden in the SDLC

There should be a mindset of significance and to communicate there are so many requirements and challenges.

Assignment focus mindset should be followed.

Structure may be replaceable

Burden in management positions

All the employees be the end of completion

 Employees have their burden in various conditions.

Suitable for small assignments

It suits the straight projects and other conditions.

Figure 5:The difference between AGILE AND WATERFALL

(Source: https://www.easyredmine.com/ER/media/images/News/Waterfall_vs._Agile_What_is_the_Best_Approach_for_a_Software_Development_Project.jpg)

Issues with the waterfall approach

There are so many issues with the waterfall point of view. There is a comparison with the basic things of agile methodologies and waterfall methodologies in software development life cycle (Maylawati et al. 2018). There are too many things to explain more about these contents. They have to communicate but they are lacking.

The communication that actually lacks

It has highly varied interpretation and also has documents of team members.

Adaptability that lacks

There are many focused software projects that require the lack of adaptability that there is to go from unpredictable and growing exotic dependable units.

Focusing to fulfill original requirements

It demoralizes the changes. Innovations are suppressed. The elasticity prohibits the memory and that actually helps to improve better.

The communication that lacks

The consumers cause technical empathy. After that, many costly creatures gained the market. Hence, the startup companies comprehend the consumer's problem and actually gain the favor.

Issues with Agile

In recent times, the agile software development life cycle methodology doesn’t prove to be a silver bullet. After that, various kinds of offices don't obtain the advantages of the SDLC. Though agile models actually aim to solve the problems.

Organization for planning

It is actually called a fast waterfall. It needs to be implemented. This agility is truly planned and it happens in the meantime of execution in SDLC. The most suitable applications with regard to chosen organizations may approach each.

System design with no coherent

There’s no coherent system. Design is one of the top most essential parts of the software development life cycle (Qianyi et al. 2018). They have to increase the functionality of the design. There have to follow the consumer’s feedback.

Organization of agile mindset

Change system was introduced. It restricts the collaboration truly in the software development life cycle. There are many offices that have cooperation machines and are agile.

Accumulation

There have to improve functionalities in accumulation fast in software development life cycle.

Rating the mistaken metrics

The assignment also gives the image of perfection. Performance has to be found in the software development life cycle.

Question 4

Smartphone application's exact purpose of the application is the use the business application process to improve and accessibility of their level increases the customer. The mobile application points to a seamless connection and customer interaction, valuable tools that make the business modern. Having the benefits of mobile application, referred to as the most common application, types of software application run to be designed on the device mobile, tablet, Smartphone and computer such as (Reiskarimian et al. 2018). Frequently the mobile application serves users with similar services accessed on the PCs. Purpose of the primary condition of the identify smart phones of the use and the mobile application. Research of the technical issues on focused, one hand, the operating system of the Smartphone particular the consideration, and evaluated other hand smart phones are the used both in the everyday life and the economics. Finding the present compared to the study of results conducted, Smartphone uses the current analysis and shows that the Mobile application trends in particular observe the stability specificity, significant of the lack due to impulse of the new product (Sharma and Obaid, 2020). Threatened by the development of the intermediate smart phones and personal computers between the forms, size of the compact, specialization with the combined. Smartphone’s are represented by the mobile used possesses the device of multimedia mobile phones both the functions and computer portable fully, functionalities of the number of increasing the device others such as the recorded voice, cameras electronic, navigation GPS, consoles game computer, notebooks and controlled the health sensor. Mobile application software for the type of Smartphone used and devices of other mobile devices, including and services of mobile specialized software, services streaming to the client and the games of the computer.Stakeholders' uses in the involvement and application of that operation are that of the mobile project, each of two nontechnical or technical features such as the user, procedures, content or the customers (Siwakoti et al. 2019). The group of people refers to stakeholders as pretentious about the development of the software project. The stakeholders exist both in the organization and on the outside. End-user may be affected by the simple might of the process. Vested interests have a way either into product or final. Stakeholders typically are employees, suppliers, investors, customers, governments, communities, or trade associations. Stakeholders' entities internal can be both an organization to the external. Stakeholders to the key involved in planning strategy are the vested interests in the organization. Employees include the customers, union, shareholders, vendors, agency regulations, chain supply partners, owners, community members, and dependents of the organization.

IBM of the stakeholder importance engagement can help the people of the empower- stakeholder get to the involved in making the decision process. Change the sustainable stakeholders engaged in the decisions to inform the help and support to the providers needed for the long-term in sustainability. Influences the stakeholder making the decision process. Organisational that the ensure environment work remains the dynamic, rewarding, and stimulating and this is the working the good condition available organisation in the can the perform well. Stakeholders in the benefits engagement are the education that directly communicates with and allows the stakeholder perspective not only to learn, but new insights can provide to issues or the product gain to give competitive advantages (Sun et al. 2019). The decision of effective making, trust, savings cost, management risk, accountability. The first step of creating the stakeholder plan the engagement identify to clear everyone included should be. The plan includes the engagement of the stakeholders identified. Management of the stakeholder list of the stakeholder is established, The stakeholder's power on the place grid, Stakeholders define what motivates, The stakeholder influences that precise, Engagement, the strategy of the build. Five steps of the engagement plan are identifying the stakeholders. Putting in the 1st step together with the plan in engagement identifies the stakeholders, interested in the identity, influences and the power of identity, the stakeholder creates a strategy engagement matrix, choosing the software and tools for the execution. Stakeholder assessment of the engagement matrix: the stakeholder monitors the engagement changes through the tracking engagement level in the changes of each stakeholder. Used that the techniques of the communication process can be used. Ensure to use the feedback information that the stakeholder is the understood vans received. Engagement of the stakeholder matrix assessment: engagement of the stakeholder monitors the level in the tracking changes of all the stakeholders. The techniques of communication used can include process. Engagement is the stakeholder control of the process overall, the monitoring of the project relationship and the stakeholders and strategies of the adjustment and stakeholders engaging for the plans. Compares the process of the management stakeholder plan results with the stakeholders' engagement.Defines the requirement functional “ What is the system to do”, Non-functional defines the requirement “ how are they supposed the system to do ''. Non-functional are the requirements of the mobile application are the non-functional of the nine example requirements speed the determines application is fast to the response of the commands, Portability of the non-functional requirements, security of the non-functional requirements, Capacity of the non-functional requirements, Environment of the non-functional requirements, reliability of the non-functional requirements, Localization of the non-functional requirements, and usability of the non-functional requirements (Trischler and Charles, 2019). The Functional requirements are the inclusion of the Business of the functional requirements, the Functional of requirements, and the User of the functional requirements.

Testing is the non-functional usability such as stress, performance, security, etc. Functionality is the requirement of the example to use the Authentication log to try in the system. Non-functional are the requirements, for example the colour of the background screens light blue should be. Differences between the non-functional and functional requirements explain the functional requirements must work of the system, whereas Non-functional explain the while requirements the system, how should the perform. Some of the examples of the functional requirements are business core, authentication, authorization, Checkouts, transactions, and Historical data. Non-functional examples of some requirements are loading speed, a severe response to the time taken to deliver, Response to the user time, and consumption to the data limits. The functional requirements of ordering the food apps, restaurants displaying the area, menus displaying, orders placing and the transaction processing, etc. Non-functional food delivery requirements include listing the refresh box every five minutes, ten seconds within the load menu or clicking buttons; confirmation of the order must be the payment of the two seconds.

Diagram of the context is sometimes called level a to the zero data flow with the diagram, Inorder is drawn to clarify and define the system software to the boundaries. Identifies information of the flows between the external entities and the system. System software throughout the single process is shown. The current state of the context object to the application. Created new ways to understand what was going on. Information gets in the call regarding the program of your other party.

Data flow diagram is the depiction of the visual steps that will take the user goals on their achievement of the website (Zakeri and Antsaklis, 2019). The flowchart of the hybrid captures the wireframe of the major actions the user will take. A data flow diagram is the flow of the maps out in any process for information or to the system. Defined uses symbols are like the circles, rectangles and the arrows, labels of the short text plus, show that the inputs data, outputs, point storage and between the route's destinations each. 

The case diagram describes the functions of the high level and system of the scope. Diagrams also identify the interactions of the actors and the system. The case use and the use case in the actors of the diagram describe the actor how to use it, the system what the dose, but operate the systems how internally (Yeh and Taira, 2019). List of the action's use case or the step event, typically between defining the interactions of the actor and the goal of a system. Useful in the case of the techniques for clarifying, identifying and organizing system requirements. Set the possibility of the make-up of the chase sequences or the interactions between users and the system features that define the implementation and any errors of the resolution may be encountered.

 ERD application is the understanding of the help between the relationship entities within the system such as products or the order IDS. An entity-relationship diagram is composed of the 3 elements: attributes, entities, and relationships (Yang et al. 2019). Rectangle displays typically represent the entities represented by the concepts, persons, objects or the content data of events. ERD applies symbols of the sets to rectangles such as the ovals, and diamonds, and depicts the lines of interconnected attributes of their relationship. The Grammatical Structure of the mirror structure, nouns as the entities and verbs, the relationship.

Question 5

Evaluate stakeholders of the analysis are three steps of the involves the stakeholders are the identify, stakeholders are the brainstorm. Stakeholders are the prioritized, stakeholder is the prioritized level of the assessment to influence and interest of the level. Key to understanding stakeholders (Wei et al. 2019). The process of the analysis and the stakeholder identifying the project is according to the participation of the level, project into the influences and interest and project into the influence and involvement of the best determining and stakeholder of each communication throughout the groups.

The original requirements are the support are the applications objectives and the goals of the business, the Stories and the user persons of the application, the Functional, Application features, and the requirements of the non-functional, User flow, application UX, and the design notice of the application, Constraints and the dependencies with the assumptions to the application, Stakeholder and the crucial interviews. The application documents the requirements of the plan. Outline the contents of the specifications, or the goals, technical details, and the features to execute the needs of the application. Performances of the requirements of the product system: Workload, response time, platform, and Scalability.

Semantically, the complete and the correct are the interaction and the mine design from the mobile application. Captured data interaction during the capture is descriptive, the design exposes the semantics of the UIs: Screen means the elements used. Automatic and introduces the paper generating approach to the annotations of the semantic for the mobile application. Iterative and coding open the seventy-three of the elements UI and the Screens of the seven twenty (Xu et al. 2019). And the icon classes shared the application of one thirty-five icons.

There is no missing part of the Smartphone application.

Extended or improved Smartphone applications are the application size of the reduce, Networking the optimize the Smartphone application, Videos and the images optimize the Smartphone application, Screen size of the optimize, Offline the model optimizes the Smartphone application, Memory usage the improve the mobile application, The application launch time the scale down, Frame rate the smooth hit, with threads the work of efficiency.

IBM chose the organization that connects to them instantly with the applications and existing data systems and the technology of the modern environments across the. Recognized as the IBM leader in the application of the cloud management of the service with expertise in managing the all application cloud on the run, and private.
