Alpha prototype refinement
Alpha prototype refinement is a type of acceptance testing which is usually carried out at a late stage of product development and involves simulating actual use of the product by in-house developers or a team of QA (Quality Analysis) and QC (Quality Control) specialists. Typically, an alpha prototype refinement consists of systematic verification of all functions of the future product using white box and black box testing techniques.
The most time-consuming part of creating a new product is not creating a prototype, the MPV, but the process of debugging it and correcting mistakes made during the design and creation of the incremental product.
Initial testing of the product goes hand-in-hand with product development and is done by members of the product development team, who check the product against the engineering rules and requirements of the terms of reference.
When the new product is ready, it reaches the Technical Analysis and Testing Department, where the QA (Quality Analysis) and QC (Quality Control) experts begin in-depth comprehensive verification of the MPV using special equipment and testing systems. As a rule, before testing, we specify a certain set of parameters, and we know what the output should be for the proper functioning of the product. If the output is different, the QA specialist starts searching for errors with the help of a debugging engineer or a cordon, which helps to quickly locate the found errors.
Once the individual functional units of a product have been tested, they are combined into a single unit. This is not yet a fully functional product ready for release, but it is already able to work and perform at least partially its main tasks. This version of the product is called an alpha version.
Beta prototype refinement
Beta prototype refinement is the intensive use of an almost finished version of a product in order to identify the maximum number of bugs in its operation for their further elimination before the final release of the product to the mass market.
A beta prototype is the actual working version of a new product with full functionality (full product prototype), therefore the key objective of beta-tests is to evaluate the capabilities and stability of the hardware from the perspective of future users.
Unlike alpha prototype refinement, conducted by in-house QA/QC professionals, beta prototype refinement involves volunteers from the general future users of the product, who have access to the previous version of the product.
These volunteers (beta testers) are given the right to use the new product first and influence the development process to increase their satisfaction with the product. Beta testers are usually people who have already worked with this type of product and are familiar with the beta testing methodology.
Mass market product refinement
The launch of a new product (mass production) is the final stage of the new product development strategy, on the quality of organization and management, of which the commercial success of the product on the market depends.
Owners of a new product at the final stage are faced with many problems of efficient organization of production, which can be expressed in the following aspects:
1. Incorrect technical specifications –Inconsistency in specifications is one of the most common difficulties for any product manager and manufacturer. Therefore, it is important to understand that the more detailed the specification is, the better the result will be, and the less time will be spent on revision or deficiencies elimination. The best option is to involve an experienced specialist to create the requirements specification, who has experience in working with manufacturers and understands the subject.
2. Insufficient due diligence of the potential manufacturer – at the stage of launching a new product, owners tend to move quickly to mass production, and simplify the process of checking the reliability and competence of the potential manufacturer. This subsequently leads to missed production deadlines, financial losses, and a return to a new round of looking for a suitable manufacturer.
3. Mistakes and gaps in analysis of compliance of declared technical specifications of production facilities with the technical specifications of the new product – verification of compliance of actual characteristics of production equipment with technical documentation, and product specifications is not only time-consuming (especially if the manufacturer is located in another country), but also requires highly skilled professionals in the field of QA.
4. Difficulty in sourcing and selecting raw material suppliers – the launch of a new product in mass production is usually organized as part of a strategy to minimize production costs in order to attract new customers at a lower price. This in turn, motivates product owners to look for suppliers in China, which involves both the unscrupulousness of the suppliers themselves and the difficulty of organizing and negotiating with them due to language and cultural barriers.
