Here are six steps to reverse engineering your customer experiences.

In California, reverse engineering does not prove to be a wrongful act in the eyes of law, and similarly in Texas, unless reverse engineering is not prohibited, it is considered as a “fair and legal means” to obtain information.

Examples of LCE reverse engineered components include: Fire-fighting sprinkler valves. Air-conditioning and refrigeration system packed and packless valves (see below) Mechanical seals. Air conditioning system dryer housing assembly.

• 1) Understand Customer Needs.
• 2) Assess Where You Stand For Customer-Centric Experiences.
• 3) Realign Your Organization.
• 4) Establish New Methodologies And Processes.
• 5) Create A Marketing Mission Control Center.

Reverse engineering is the design process in which a product is analyzed or recreated using a physical part as a starting point. During the design process for a new product, modeling can be used in order to test, evaluate and validate the conceptual design.

3.2 Reverse Engineering It is a process of examination, not a process of change or replication. The overall goal of reverse engineering is to facilitate understanding of software systems, whether tools themselves undertake to understand their subjects or simply provide aids to help a human user to that end.

6 Benefits of Reverse Engineering

• Exploring existing designs and maneuvers.
• Reconstructing a product that is outdated.
• Discovering any product vulnerabilities.
• Bringing less expensive & more efficient products to the market.
• Creating a reliable CAD model for future reference.
• Inspiring creative minds with old ideas.

Reverse engineering broadly take several forms. Identify the four types of Reverse Engineering (RE) in semiconductor-based products and briefly explain each. This is the simplest type of RE in the electronics arena.

Reverse engineering can be performed from any stage of the product cycle, not necessarily from the functional end product. There are two components in reverse engineering: redocumentation and design recovery. Redocumentation is the creation of new representation of the computer code so that it is easier to understand.

8. ______________ comes under tools for reverse engineering (RE). Explanation: Disassembler is the opposite of assembler. As assemblers are used to convert code written in assembly language to binary/machine code, disassembler does the reverse for cracking purpose & it comes under reverse engineering tool.

Explanation: Users are always the most important stakeholders.After all, without users or customers, what’s the point of being in business?.

The main types of requirements are: Functional Requirements. Performance Requirements. System Technical Requirements.

A Functional Requirement (FR) is a description of the service that the software must offer. It describes a software system or its component. A function is nothing but inputs to the software system, its behavior, and outputs.

Functional requirements capture the intended behavior of the system. This behavior may be expressed as services, tasks or functions the system is required to perform. The document should be tailored to fit a particular project’s need.

Functional requirements are product features or functions that developers must implement to enable users to accomplish their tasks. So, it’s important to make them clear both for the development team and the stakeholders. Generally, functional requirements describe system behavior under specific conditions.

10 Tips for Successful Requirements Gathering

1. Establish Project Goals and Objectives Early.
2. Document Every Requirements Elicitation Activity.
3. Be Transparent with Requirements Documentation.
4. Talk To The Right Stakeholders and Users.
5. Don’t Make Assumptions About Requirements.
6. Confirm, Confirm, Confirm.
7. Practice Active Listening.

How do you discover and elicit non-functional requirements?

1. Stakeholder goals, values, and concerns – Talk to the stakeholders!
2. Legacy system and/or existing platform constraints – the analyst takes a look at constraints dictated by the environment into which the new system must fit, the existing systems with which it must integrate, and the technical platform(s) it must use.

Requirements Gathering Steps

• Step 1: Understand Pain Behind The Requirement.
• Step 2: Eliminate Language Ambiguity.
• Step 3: Identify Corner Cases.
• Step 4: Write User Stories.
• Step 5: Create a Definition Of “Done”

Types of Non-functional requirement are Scalability Capacity, Availability, Reliability, Recoverability, Data Integrity, etc. Example of Non Functional Requirement is Employees never allowed to update their salary information. Such attempt should be reported to the security administrator.

Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

Recoverability – Logical Requirement: The ability of the system to resume business functionality upon logical failure of application managed business data.

Non-functional requirements are typically found within their own section in an FRD. This section usually follows the functional requirements and will be labeled “non-functional requirements”.

Scalability is a non-functional property of a system that describes the ability to appropriately handle increasing (and decreasing) workloads. Scalability competes with and complements other non-functional requirements such as availability, reliability and performance.

The architect might not be responsible for defining the non-functional requirements, but they’re definitely responsible for fulfilling them. I agree, typically the architect will fulfil the requirements rather than define them, although sometimes you need to define them too.

Usability is a non-functional requirement, because in its essence it doesn’t specify parts of the system functionality, only how that functionality is to be perceived by the user, for instance how easy it must be to learn and how efficient it must be for carrying out user tasks.
