Posted on by Imarticus Learning

You will have to hire a web developer and designer as soon as you decide to create a website. However, did you know there are significant distinctions between web design and development? 

Website design and development are essential in creating websites, software platforms, and even the everyday applications used on smartphones and tablets.

best digital marketing course

Understanding the differences and similarities will help you comprehend how they work together and why they are essential for any modern web project.

In this writing, we will discuss the differences between website design and website development.

What is web design? 

Web designing is the organising, conceptualising, and planning process that results in a practical website that offers a satisfying user experience. 

The user experience is at the heart of website design. Various features are presented on websites that make them simple to navigate.

 To make a website user-friendly and efficient, it is necessary to work on every component that users interact with. This enables users to quickly find the information they require and looks visually appealing. 

Together, these elements determine how well a website is designed.

What do web designers do?

A website’s design and layout are put together by web designers using their technical skills and experience while remembering the client’s needs. 

They are skilled in using software for design to produce visual elements and have a proper understanding of UI and UX concepts. 

These professionals use their knowledge and talents to incorporate the company’s identity into the website’s design elements.

Visitors evaluate their engagement with a particular website based on its design and navigational ease. 

To get the attention of their visitors, web designers also pay attention to the website’s creative and aesthetic aspects and use various design concepts like symmetry, colour schemes, and dimensions. 

They also use computer languages to work on image and video placement, fonts, and layout creation.

What is web development? 

Web development is building a website or online application from the ground up. It may involve developing the user interface, designing the website, and adding efficiency. 

HTML, CSS, and JavaScript are just a few of the languages used for programming that web developers frequently use.

Anyone who wants to develop a website or web application needs to have web development skills. Due to the rising need for online services and goods, it’s also one of the abilities in the most demand right now. 

What does a web developer do?

A web developer builds the front end and back end of a website. They are also responsible for ensuring the website complies with all accessibility, technical, and design standards. 

They could also be in charge of modifying or modifying already-existing websites. Most web developers hold degrees in computer science or a closely related subject. 

HTML, CSS, and JavaScript are just a few programming languages they frequently use. In addition to building websites, web developers could also work on developing unique applications for the companies or organisations they’re associated with.

Difference between website development and website design 

The key difference between website development and website design are as follows:

Website development  Website design 
The structural design of websites and writing the code that makes them work are frequently the main goals of web development. Graphics and logos are typical aesthetic elements used in web design. 
Software engineers proficient in writing original code are typically the ones who build websites. Generally, talented designers proficient in Photoshop and other graphic programmes create websites.
Web developers check a concept’s viability from a financial and technological viewpoint before moving on to the next level of website coding. By constructing a mockup based on visual, UX, and UI concepts, web designers create the aesthetic and concept of a website.
These are in charge of switching those designs into functioning websites. To construct a website’s layout and functionality, developers employ web tools.  The majority of web designers study typography and other graphical elements of websites.
A web designer can be hired for far less money than a web developer. A web developer is hired at a higher pay than a web designer.

Similarities between website design and website development 

Now that we understand the differences between web design and development let’s look at their similarities. 

Understanding the similarities, you can better understand why web designers and developers are necessary. 

  • Both will contribute to an engaging user experience.

The user’s experience has to be your first concern if you want to create a good experience for your clients. It also helps ensure that the visitors return to the website. 

Why? Customer satisfaction ensures that customers will positively associate with the website and, consequently, the products. Customers who have a negative experience using your website will become upset and choose to do business elsewhere.

How do web design and programming interact to accomplish this? There is a simple fix. The development ensures the website is functional, while the design ensures users can easily navigate your website. 

No matter how beautiful it may be, a website that doesn’t work properly is useless to users.

  • Both parties must work together for the site to be successful.

If you still need to figure it out, you must invest in website design and development. 

Both parties must work together to create a unified, helpful website. Without design, a website would appear impersonal. 

Websites that need to be built will operate effectively. Together, design and development create a website that is truly exceptional to use.

Conclusion 

A web designer is a visual artist who creates a website’s usability, structure, and aesthetic appeal. On the other hand, a web developer creates and updates a website’s basic framework.

Website design and development are both essential parts of building any website. Creating a good website for any business is one of the first steps for marketing the brand to its targetted audience.

Risk Management and Analysis in Investment Banking

Posted on by Imarticus Learning

Investment banks face a variety of threats that can affect their economic viability and performance as a whole. Analysing and managing risks in investment banking, thus, has a vital function in maintaining the financial stability of the institution. 

Investment Banking analyst

Simply put, risk analysis entails assessing the probability and potential effect of a negative event, such as market volatility, operational failures, or legal and regulatory non-compliance. Risk management pertains to spotting and preventing risky behaviours or tactics in order to safeguard financial assets from loss.

This article will explore these two crucial components of investment banking in detail.

What is risk management?

In investment banking, risk management refers to recognising, evaluating, and addressing risk factors that occur all through the business life cycle.

The risk appetite, which is based on the current and prospective risk profile as decided by the Investment Bank’s Council [2], is the key element of the investment bank’s risk management plan. The risk appetite serves as a decision-making framework, ensuring that the risks are taken in accordance with the investment bank’s goals and level of risk tolerance.

Investment banks must employ strong and effective risk management frameworks to ensure resilience and survival in a fast-changing economic landscape. According to McKinsey research, technological advancements, macroeconomic shocks, and banking scandals will determine the future of bank risk management. 

The research suggests that by 2025, investment banks will focus on building resilience and improving their risk culture, governance, and data management capabilities to address these challenges effectively.

Types of risks in investment banking and how to manage them 

Some common types of investment banking risks include market, credit, operational, and liquidity risks. Read below to learn the risks and ways to manage them.

  • Market Risk – Potential risk of loss arising due to market variables such as currency rates, inflation, and interest rate risk. To manage this risk, investment banks could rely on a variety of approaches, such as hedging, diversification, and portfolio optimisation. 

Hedging involves taking positions in securities that offset the risk of other positions in the portfolio. Diversification involves spreading investments across different asset classes to reduce risk. Portfolio optimisation involves using mathematical models to allocate assets in a portfolio to minimise risk while maximising returns.

  • Credit Risk – Another critical risk that investment banks face is credit risk. Credit risk is the risk of default by borrowers or counterparties. Investment banks use various techniques such as credit analysis, credit limits, and collateral to manage credit risk. 

Credit analysis involves assessing the creditworthiness of borrowers and counterparties. 

Credit limits involve limiting the maximum exposure investment banks can have to individual borrowers or counterparties. Collateral involves taking assets from borrowers or counterparties to secure loans or other transactions.

  • Operational Risk – It is the risk of loss caused by insufficient or failed internal organisational procedures, systems, or human error. Investment banks can mitigate this risk through the application of various approaches such as risk evaluations, internal surveillance, and crisis management.

Risk assessments involve identifying potential risks and assessing their likelihood and impact. Internal controls involve implementing procedures and policies to mitigate operational risk. Contingency planning involves preparing for potential operational disruptions and having plans in place to respond to them.

  • Cyber Risk –  The probability of loss resulting from online threats, data breaches, and other incidents concerning cybersecurity is referred to as cyber risk. To manage cyber risk, investment banks can adopt a range of tactics such as analysing cybersecurity risks, employee training, and planning crisis responses.

Risk analysis in investment banking

Risk analysis is used in investment banking to detect, examine, and control various types of risk to assure that the banking institution’s risks are within permissible limits and do not compromise its financial stability or image.

Typically, investment banks use complex risk analysis models utilising statistical and financial data to calculate the likelihood and extent of different risk events. These models can assist in identifying potential hazards and opportunities as well as providing insights into the best course of action for risk management.

Overall, risk analysis plays a critical role in investment banking by helping to identify potential risks and opportunities and guiding the development of effective risk management strategies.

Conclusion

Managing risks in investment banking is an inherent part of the financial system. Regulations and fines imposed after the financial crisis have transformed risk management in banking, and the next decade is expected to bring even more sweeping changes to the field.
