Loose Ends Introduction Requirements and specifications are very important components in the development of any embedded system. Requirements analysis is the first step in the system design process, where a user's requirements should be clarified and documented to generate the corresponding specifications.
As implied above, the initiative and further procedure for the preparation, implementation and management of the documents is a procedure in itself which should be described. These SOPs should at least mention: It should be established and recorded who is responsible for the proper distribution of the documents, the filing and administration e.
Finally, it should be indicated how frequently a valid SOP should be periodically evaluated usually 2 years and by whom. Only officially issued copies may be used, only then the use of the proper instruction is guaranteed. In the laboratory the procedure for the preparation of a SOP should be as follows: In principle, the author is the person who will work with the SOP, but he or she should always keep in mind that the SOP needs to be understood by others.
The author requests a new registration number from the SOP administrator or custodian which in smaller institutes or laboratories will often be the HoL, see 2. The administrator verifies if the SOP already exists or is drafted. If the SOP does not exist yet, the title and author are entered into the registration system.
Once the writing of a SOP is undertaken, the management must actively support this effort and allow authors adequate preparation time. In case of execution procedures for investigations or protocols, the project leader or HoL could do the testing.
In this phase the wording of the SOP is fine-tuned. Revisions of SOPs follow the same procedure. The make-up of the documents should meet a minimum number of requirements: Categories can be denoted with a letter or combination of letters, e.
The first page, the title page, should mention: It is possible to record the authors centrally in a register ; f. The necessary equipment, reagents including grade and other means should be detailed.
A clear, unambiguous imperative description is given in a language mastered by the user. It is recommended to include criteria for the control of the described system during operation.
It is recommended to include a list of contents particularly if the SOP is lengthy. It is recommended to include a list of references. However, once the draft is made, with the use of word processors and a simple distribution scheme of persons and departments involved, the task can be considerably eased.C (/ s iː /, as in the letter c) is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.
