Until recently, the observation-intensive approach needed for accurate, very short range forecasts, or "nowcasts" , was impracticable. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were beyond overcoming. Fortunately, scientific and technological advance have overcome most of these problems. Radar systems, automated weather instruments , and satellites are all capable of making detailed, nearly continuous observations over large regions at a relatively low cost. Communication satellites can transmit data around the world cheaply and immediately, and modern computers can quickly compile and analyze this large volume of weather information. Meteorologists (气象学家) and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, nowcasting is becoming a reality.

Callisto Retail (Callisto) is an on-line reseller of local craft products related to the historic culture of the country of Callistan. The business started ten years ago as a hobby of two brothers, Jeff and George. The brothers produced humorous, short video clips about Callistan which were posted on their website and became highly popular. They decided to use the website to try to sell Callistan merchandise and good initial sales made them believe that they had a viable business idea.
Callisto has gone from strength to strength and now boasts sales of $120m per annum, selling anything related to Callistan. Callisto is still very much the brothers’ family business. They have gathered around themselves a number of strategic partners into what Jeff describes as a virtual company. Callisto has the core functions of video clip production, finance and supplier relationship management. The rest of the functions of the organisation (warehousing, delivery and website development) are outsourced to strategic partners.
The brothers work from their family home in the rural North of Callistan while other Callisto employees work from their homes in the surrounding villages and towns. These employees are involved in video editing, system maintenance, handling customer complaints and communication with suppliers and outsourcers regarding inventory. The employees log in to Callisto’s systems via the national internet infrastructure. The outsourced functions are handled by multinational companies of good reputation who are based around the world. The brothers have always been fascinated by information technology and so they depend on email and electronic data interchange to communicate with their product suppliers and outsourcing partners.
Recently, there have been emails from regular customers of the Callisto website complaining about slow or non-delivery of orders that they have placed. George has commented that this represents a major threat to Callisto as the company operates on small profit margins, relying on volume to drive the business. He believes that sales growth will drive the profitability of the business due to its cost structure.
Jeff handles the management of outsourcing and has been reviewing the contracts that exist between Callisto and its strategic partner for warehousing and delivery, RLR Logistics. The current contract for warehousing and delivery is due for renewal in two months and currently, has the following service level agreements (SLAs):
1. RLR agree to receive and hold inventory from Callisto’s product suppliers.
2. RLR agree to hold 14 days inventory of Callisto’s products.
3. RLR agree to despatch from their warehouse any order passed from Callisto within three working days, inventory allowing.
4. RLR agree to deliver to customers anywhere in Callistan within two days of despatch.
Breaches in these SLAs incur financial penalties on a sliding scale depending on the number and severity of the problems. Each party to the contract collects their own data on performance and this has led to disagreements in the past over whether service levels have been achieved although no penalties have been triggered to date. The most common disagreement arises over inventory levels held by RLR with RLR claiming that it cannot be expected to deliver products that are late in arriving to inventory due to the product suppliers’ production and delivery issues.
