1)Differences between generic software product development and custom software development.

Generic software can be defined as: ‘stand-alone systems produced for an open market – production controlled by the development organisation’, whereas custom software can be defined as: ‘commissioned systems by a particular customer – production controlled by the customer organisation’.

Generic software has to include as many functions as possible as it will have a very wide use base, and will need to provide functionality and usability to that wider range of users. Generic software also has to be developed to be very reusable and have components that can be easily modified or added to at a later date, making the software as upgradable as possible so it can have a longer useful lifetime.
The development of custom made software differs from this because the uses of the software are for a lot more specific of a customer base, and usually would include components that would need to be freshly written for the software; as if generic components already existed to perform the requirements of the users then they would have brought off the shelf software. Custom software development is usually a lot more based around communication with the specific needs of the users the software is being created for, to insure the finish product will meet the needs of the end user, whilst still being made of separate components that make the software as upgradable as possible. However as custom software is usually developed by one company/group of developers for a specific user, the upgradability and maintainability of the software will always be limited as if the knowledge from the original creators is lost, possibly through hiring of new IT support staff, then the new staff would take a long time to get to grips with the custom software and would risk damage to it when making modifications or upgrades to it at a later date.

Generic software development is the one done for "General Purpose" audience whist "Custom Software Development" is done to satisfy a particular need of a particular client. General Purpose software development is tough as compared with Custom made; not by the skills required to develop the application but by the design and marketing point of view.

In General Purpose application/product design and development, you will need to "imagine" what an end-user require. Here, the term "end - user" has no face; you have to imagine it. Market Surveys and general Customer Demand analysis may help a company to reduce the risk factor and think about some innovations over existing similar solutions.

On the other hand, in Custom Made application/product development, you have a specific face of "end - user" in front of you. You know whom you need to satisfy. Understanding the need and Analyzing it to get the best out of it is a challenge here. Planning and reaching the goals within dead-line adds a value to your software development excellence as a professional service provider.

Inventory

...facility location and design, inventory and distribution planning, capacity and production planning and detailed scheduling. Only a small proportion of this work directly addresses the issues faced in the pharmaceutical sector. On the other hand, this sector is very much ready for and in need of sophisticated supply chain optimisation techniques. At the supply chain design stage, a particular problem faced by this industry is the need to balance future capacity with anticipated demands in the face of the very significant uncertainty that arises out of clinical trials and competitor activity. Efficient capacity utilisation plans and robust infrastructure investment decisions will be important as regulatory pressures increase and margins are eroded. The ability to locate nodes of the supply chain in tax havens and optimise trading and transfer price structures results in interesting degrees of freedom in the supply chain design problem. Prior even to capacity planning comes the problem of pipeline and testing planning, where the selection of products for development and the scheduling of the development tasks requires a careful management of risk and potential rewards. At the operation stage, it is often difficult to ensure responsiveness. Most pharmaceutical products involve primary active ingredient (AI) production (often multi-stage chemical synthesis or bioprocess) and secondary (formulation) production. Both of the stages are...

...Busa 6800: Strategic Management Mid-term 1. Complements – define and apply (pg. 52/53) Complementors: Players with whom a firm interacts but may not necessarily transact. The concept of complementors is perhaps the single most important contribution of value net analysis Complementors typically are products or services that have possible impact on the value of a firm 's own products or services. Those who produce complements are usually referred to as complementors. Powerful computers are of no value to a user unless there is software that runs on them. Similarly, new and better software is possible only if the hardware on which it can be run is available. This is equally true in the video game industry, where the sales of game consoles and video games complement each other. Nintendo' s success in the early 1 990s was a result of their ability to manage their relationships with their complementors. They built a security chip into the hardware and then licensed the right to develop games to outside firms. These firms paid a royalty to Nintendo for each copy of the game sold. The royalty revenue enabled Nintendo to sell game consoles at close to their cost, thereby increasing their market share, which, in turn, caused more games to be sold and more royalties to be generated. 2.

Their strengths include innovative techniques, branding, and design. With strengths, there come weaknesses for companies. Target’s weaknesses include the lack of geographic locations and numerous litigation cases. Competitor competition, along with a recovering economy, serves as threats to the retail industry. There are many opportunities for Target, such as expansion into the global market, continued growth in private label, and broadening their target demographic to increase the market share. II. Company Background and Mission, Vision, and Values Statement In 1962, the first Target store was opened by the Dayton Dry Goods Company in Minnesota. Target is one of the few franchises to have been established for such a long period. In 2002, Target became the second largest retailer in the United States (Target, 2013). Target could do this by adapting to the changing environment and meeting customers’ needs and wants.
