External supplier development process

The following process is applicable for changes to any component of computer technology that performs functions on regulated products, including hardware, peripheral devices, system software and utilities, application software, documentation, and communications hardware and software. These components can be either purchased from an external supplier or developed in house by the company or its designee. 

Key players that can be identified in this process are as follows all levels of management, the persons responsible for the processes and activities to be performed under GxP, suppliers (external suppliers as well as internal system developers), IT/system managers (including service providers, if applicable), system users and Quality Assurance (QA). It is highly recommended to also involve the Purchasing and/or Legal departments in the process if new modules, updates or extensions are required. Table 13.3 indicates the basic roles, responsibilities and tasks for the key players in order to validate systems and to keep them validated. Most of the responsibilities and tasks are equally relevant for the period prior to initial validation and for keeping the systems validated. 

The same can be said for the procurement and supply function which places the greatest emphasis on those operational effectiveness business activities associated with performance management (28.75%), process enhancement (27.62), IT and Internet solutions (22.79%). The function also puts considerable effort into its key functional role and responsibility associated with supplier selection and negotiation (22.60%), supplier development (19.11%) and segmentation of spend (11.62%) activities. The function clearly understands that it must deliver external resources efficiently and effectively at the operational level. This is borne out by the fact that it devotes least effort to the more strategic make/buy (9.20%) business activities. 

The findings here seem to confirm that there is some duplication of effort across functions, but also that performance management, product and competence development, process and system improvement and external environmental analysis (of markets, competitors and suppliers) are the primary business activities for which tools and techniques are being used within companies as a whole. This seems to support the view that, when managers use tools and techniques, they appear to understand by and large what are the right tools for the job. This is clearly a good part of the metaphorical curate s egg of tool and technique use. 

The laboratory shall identify the inputs that affect the design and development of the laboratory processes and facihtate their effective and efficient performance. Inputs are defined from external as well as internal needs and expectations. External inputs are drawn from customers, suppliers, users of the laboratory output, statutory and regulatory requirements, international or national standards, industry codes of practice etc. Internal inputs are drawn from policies and objectives, needs and expectations of people, technological development, past experience etc. 

A critical but often overlooked aspect of the technical service function is the value of relationships that develop between more senior members of the technical service staff and their colleagues at customer sites. Professional relationships provide value both to supplier and customer by virtue of the tmst and respect generated in a successful technical service interaction, analogous to the types of mutually valuable relationships that can develop between supplier sales personnel and a customer s purchasing personnel. A more efficient process of gathering and dispersing new and useful technical information can result from these relationships, because the persons involved work in different environments and are exposed in the course of their work to different external sources of information. 

The computer system specification includes information on how the operation can be controlled using the features in the selected application package. A review of the process must be conducted to familiarize the computer technology supplier and/or developer (external or in-house) with the requirements defined in the requirements specification deliverable. This system view is essential, particularly when the software must interface with other elements such as hardware, people, and databases. The review of the process includes the further gathering of requirements at the system level, and top-level design. 

The expected time to execute home appliances development projects in man-year is longer than for modules or elements. Bigger core teams should be collocated in the same office to enable smooth inter-team communication. Some of the activities for vacuum cleaner motor development, which were managed before by external team members located in functional departments, are now managed by core team members. For example, industrial designers inside a core team communicate directly with end users, a specialist for process planning has direct contact with tool suppliers. Direct communication reduces the probability of wrong data interpretation and improves the transfer of information inside the core team. It is known that increased physical distance between employees workplaces dramatically reduce the frequency of informal communication and data transfer [2]. 

Box and Tiao (1975) subsequently developed a procedure for analysis of a time series in the presence of known external interventions. In their approach, there are two types of interventions - pulses and steps. A pulse is an intervention with a finite duration (typically one time period), while a step involves a permanent change or intervention (e.g., the introduction of a new governmental regulation or the permanent loss of a supplier). Intervention analysis is a statistical procedure that enables the researcher to evalnate the impact on a time series, as represented by an ARIMA (Autoregressive Integrated Moving Average) process.
