Simple Packaging: Your Guide to Branded Design

Packaging. Such a common, everyday word. It has become embedded in the lives of consumers that, unfortunately, many businesses have forgotten just how important and valuable it is. The thing is, even that seemingly simple packaging holds immense power. It can either make a buyer spend money or make them put it back on the shelf and pick up another similar item. After all, consumers, for the most part, see only the packaging when they purchase items directly from a store. Just think about it, packaging covers about 100% of most products you see in stores. There's also the fact that what covers a product - and what's on it - makes up about a third of most purchasing decisions. If you’re having trouble thinking up methods on how to design packaging and custom boxes, worry not, as we’re here to help. In this post, we’ll give you some of the best packaging design tips. It All Starts with Understanding How Packaging Works : First, let's talk about what packaging is and how essential it is to branding. Why it has grown to become a $9-billion industry. At its core, the packaging is the method and the materials used to contain, cover, safeguard, and transport items. The methods can vary from cleaning to preserving. Materials differ too, with the most common being cardboard, paper, plastic, metal, glass, and metal. The thing is, packaging has many more roles than just giving products a pretty face. Indeed, it's a powerful tool to attract the attention of buyers. It's crucial in branding awareness and recall. More than that though, it's vital in helping reduce product waste. For instance, research has shown its great importance in keeping food and beverages edible. In other industries, its ability to protect items significantly reduce potential damages, which then lessens the need to throw them out for replacement products. In the food industry, effective packaging for food products can be made with sustainable materials. In fact, a recent study noted that socially-responsible packaging now plays an important role in buying decisions. More than half (52%) of the study's participants noted they spent money on a product/service from companies using eco-friendlier packaging methods. Also, take note that packaging also has a lot to do with product safety. This is especially true for products that are for human consumption, including food, beverages, and medication (including vitamins and supplements). You want your customers to safely reap the most out of their purchase, and at the same time, remain in compliance with packaging laws and regulations. Simple Packaging and the Immense Branding Power It Boasts Of : You want to make sure your product, as soon as it's ready, goes on display right away. But you can't really say it's ready, not unless you've also made certain that its packaging is 100% ready to go. Whether you go for a box, bag, wrapped, taped, or glued packaging elements, every element of your packaging should incorporate what's mentioned above. You also need to ensure that it possesses all the right components for effective branding. Consider this: The average grocery stores now sell 40,000 more products than they did two decades ago. In a place where your products compete with many of these said items, how you package your brand's offers can make or break the deal. Again, it can either make consumers want to put it in their shopping carts and pay for it or put it back on the shelf and buy a competitor's product instead. Essentially, product packaging is your primary selling tool. After all, it's the most tangible method to represent your product and brand to your target market. Keep in mind that you only have seven seconds to leave a positive impression on consumers, so you need to make them see instantly why they'd want to spend money on your offers. All these said you need your product packaging to have eye-catching features. But it also needs to retain functionality and should be economical. And for eco-friendly consumers, sustainable materials. The Right Elements that Go into Successful Packaging : Just as how you'd carefully review all the elements of your social media marketing campaign on Facebook, the same goes true for inspecting all your product packaging elements. Again, how you package items can instill better brand awareness and recall. For it to help your brand achieve success, it needs to boast of the right elements. What elements are these? Brand logo, color, shape, and typography are the most essential. Brand Logo : The position itself of your brand on your packaging can also make or break a buyer's decisions. Therefore, you want to implement the best positioning strategy for your brand logo for consumers to notice it right away. Also, keep in mind that logo placement affects brand recall. Color : Color affects - either in a positive or negative manner - consumer buying decisions. For instance, studies reveal that 85% of consumers buy products because of its color. They also cite that color can raise brand awareness up to a whopping 80%! Of course, you still need to base the colors you choose on your products/services. For example, if you want to stir emotions of urgency and leave an "energetic vibe," you'd want to consider using red as a primary color. Just check this service and see how your mind and body reacts to it. Shape : Even the shape of your product packaging can already say a lot about the product it contains! You should then use this as another tool to better market your brand's offers. For instance, angular shapes speak to men, while curved shapes are more ideal for female-centered products. Packaging for Ease of Use and Better Branding : These aren't the only reasons you need to be more aware of the great power behind the packaging. Even simple packaging can elicit an "Ooh" from potential buyers rather than just a regular "Ahh." So, as early as now, especially before launching new products to the market, make sure your packaging has all the vital elements for better branding. And for more business tips and tricks that'll help you better shape your brand, make sure you check our blog.

Software Development Team

The development of any intellectual product is initially aimed at success in its implementation. In this regard, it is extremely important to ensure the proper quality of the software, application, or another result of the work. A properly selected Software development team is several professionals who can organize the work of creating software in a short time and at minimal cost to the investor, and also guarantee the relevance of the product. How to choose the correct development team? The level of professional training and work experience of specialists involved in the development of an intellectual product depends on the complexity of the work, as well as on the budget of the investor. Among all specialists actively offering their services on the market, development companies choose the following team members: 1. Universal specialists In the labor and services market, you can meet craftsmen who position themselves as highly qualified specialists who can solve any issues. As a rule, these people have extensive experience and knowledge in the matter under consideration. They can easily handle the development of a simple application. At the same time, when creating complex software, you will need deeper knowledge that generalists don’t possess. 2. Profile specialists These team members can be designers, programmers, content managers, or just engineers. They have the appropriate education and have extensive knowledge and experience in some competitive fields. They require the expert opinion, as well as full management of a specific part of the project, well-coordinated work in a team, and timely transfer of data and development results to related specialists. 3. Combined team Recruited to create the most complex applications or software. The team includes both generalists and specialized specialists. When developing an intellectual product, a horizontal control system is used. Each member of the team reports directly to the top management. When developing software, the worthwhile ideas of each employee are taken into account, and cross-checking is also provided. This project management technique is considered the most effective, as it allows you to minimize costs and achieve the expected results. Market experts and representatives of large IT companies recommend that when recruiting a team for a development team, ensure an approximately equal balance of generalists and specialized specialists. Moreover, each team must have either an official or an informal leader, who will be able to coordinate all tasks between other members of the collective. How to determine the optimal number of team members? There should be exactly enough team members to ensure the implementation of the project and the fulfillment of the technical task from the customer with the utmost accuracy, strictly on time. The following important factors influence the team size: The complexity of the task. The uniqueness of the development. Deadlines, defined by the customer and technical restrictions. The allocated budget for the implementation of the project by the investor. Provided resources to complete the task. In practice, to develop primitive software, no more than 2 – 4 people will be required. if it is necessary to implement a project of increased complexity, 7 or more team members may be required. What are the functions of team members? Most often, members of a pre-selected team perform the following roles in the development of a smart product: The key link is the investor or the customer of software development. It is he who provides information about what the final product should look like. Managing person – a team member who has experience in project management. He coordinates all specialists, combines ideas, draws up calendar schedules, conducts meetings, and issues final or intermediate results to the customer. The software architect is the most important specialized or generalist specialist. It provides the primary implementation of the general idea in strict accordance with the terms of reference. Subsequently, such a person is an assistant to the head, and he is sent for verification, as well as the assembly of all the developments of the work of the entire team. Engineers and ordinary developers – there may be several such members in the team. They are responsible for product development and software uptime. Designers – the area of responsibility of these specialists includes the design of attractive templates for users, as well as interfaces. Their work is related to how the product will be perceived by the end consumer. The main task of the designer is to create an easy-to-use and attractive product that will attract the interest of as many users as possible. The controller is a quality control engineer or an audit specialist. It checks the operability of the product, the compliance of the developments with the technical task, and also ensures the elimination of errors, which helps to improve the quality of the software. Analyst – a person who works in a team as an expert. He owns the needs of the market, as well as the industry for which the application is being developed. The demand for the software depends on this person, as well as its competitiveness, in comparison with other similar programs. Regardless of the assigned functions, the main degree of responsibility of the leader is to maintain a healthy spirit and friendly relations in the team. All team members should periodically come together for an online or face-to-face briefing, share results and problems. Upon discovering the first difficulties, each of the developers must notify all other team members about this. A focus on results is the main key to success. Requirements for the team in software development To achieve positive results, each team member must obey the internal regulations and follow the following important rules: Communication is carried out only in real-time, without delay in responding to a question or a task. All issues should be put up for public discussion – the principle of business transparency. All team members must trust each other. Each team member performs only their function. The composition of the team remains unchanged until the completion of development. In the collegiate discussion of questions, all of them are reflected on the board. Despite the above principles and examples, there is no single formula for creating an effective team in practice. To create a team, it is recommended to contact experts or recruitment agencies, and if the company already has the personnel, it is recommended to select developers not only according to the criteria of knowledge and experience but also according to the principle of psychological compatibility. An effective result is achieved only with a healthy spirit in the team and a competent distribution of tasks.
