Outline and summarize this
Ordering (establishing good procedures) It is very unlikely your school has in place the kind of ordering procedures you will need in (i) First acquiring and installing everything for a good, functional lab, and (ii) Continued purchasing of supplies, additional equipment and additional software throughout every school year. Most school budgets are composed largely of staff salaries, handled by accounting. Once classrooms are equipped with furniture, ordering is mainly textbooks (ordered in May for the following school year) and expendable supplies such as workbooks, paper, art supplies.
The computer lab will need its prorata share of these types of supplies. Other things typically forgotten for the computer lab are storage (disk cabinets and boxes, shelving, lockable large cabinets for tools, spares, paper, ink and toner cartridges) shelving (for software boxes, manuals, disk boxes, books). In general, you will be ordering small amounts of these types of things throughout any school year, as needed, and as your budget permits. You will be conferring with subject-matter or elementary classroom teachers, scanning catalogs and reviews, and ordering new software throughout the school year--some for evaluation for site license or quantity purchase, and some just as single items or 5-copy lab packs.
Unlike other types of school purchasing, you may quite often find shipments are defective in various ways. Items arrive broken. Software is defective on its disks and will not load or has some other problem. Manuals are missing. Some tiny part is not in the packing boxes, though you searched the packing material very careffully. Items on an order are not in the box, and you see they are marked BO (back-order) on the packing slip--or you don't see it, you're being billed as if they were shipped, but they aren't there. You will be getting evaluation software, to try out with the students for 30 or 45 days, intending perhaps to buy it on next year's budget, if liked--and this generally will be shipped with an invoice, for which you receive a credit memo after the evaluation materials are returned. If you don't get good procedures in place from the git-go, you will wind up having no recourse for missing or broken things, paying for some things more than once, paying for things you never received, paying for evaluation ware you didn't want after all, and not paying for things so your school's credit record suffers
. Without a purchasing procedure that relates directly to your budget--whatever it is--you will inevitably overrun that budget, for you cannot plan your purchasing--adjust your wishes for the best for the kids--to the reality of what money is budgeted for the computer-lab this year. There will also be budget situations such as "no money was included for repairs" as well as the cost of shipping items in for repair. These procedures should provide your school with solid data that is a handle on budgeting for other years. You can only get a feel for real operating expenses if you have some system in place that lets you examine actual costs.
The first few years costs will be high--but they will never drop to just replacement of expendable supplies. The reason is that software (and hardware) are constantly evolving. Newer--and much better--products are constantly being developed. You will want some of these every year. Some software--though this isn't routine for small educational packages--is routinely upgraded each year. Cost of upgrades is typically about 1/3 to 1/2 the original cost of the software. You won't be eligible for these upgrades--or even notified about them--unless you've registered your software. A reason to write the registration number on the disks is that many software install procedures require you to enter that number at some point. Software does become corrupted in spite of all the protections we try to give it in the student lab (and elsewhere) and you must re-install. You will have to re-install if hard drives required any kind of major surgery, including the kind you do yourself by running disk repair software utilities.
Another aspect of purchasing is software itself, a different type of object than hardware. Though it seems as if you are buying it, actually you are only licensing it, and there are generally some specific conditions for its use (how many copies may be installed for a site license, for example). In every software package, however inexpensive, you will find a registration postcard. Some software--usually not inexpensive kidware--comes serial-numbered, too. Always fill out the registration card, and always keep a record of serial numbers. If a serial number isn't printed on the #1 disk in the set of originals, write it on that disk, as well as in your working lab log. Serial numbers, purchase dates should be recorded for all hardware, and taped conspicuously to the back of it. This info will be required for warranty service and for your school's insurance. When you make calls to technical support, especially about software, they often want to know your serial number, even if you have mailed in the registration postcard. They will generally also want to know the version number of software, especially of device driver software for printers, scanners, cameras and other attachments, but kidware and major applications have bugs in earlier versions, too, that are fixed in later ones. If you are registered, and have trouble caused by bugs, tech support can tell you this and send you the bug fix upgrade (which, annoyingly, you sometimes have to pay for).
Since much kidware isn't serial-numbered, you should enter its purchase date on your budget lab management spreadsheet, so it is tied to purchase order number, invoice or packing slip number, and date, in a way that will let you retrieve this info easily. You cannot count on your school's bookkeeping or accounting people to be able to do this. It is quite unlikely they are using the right kinds of software for it, and their paper procedures were not created with the idea of any kind of inventory management in mind.
For hardware, it is also a good idea to record "connectivity info" about cables and ports by each port and tape that to the machine. School computers tend to get moved around a lot, especially during summers when buildings get a major cleaning and sometimes some remodeling or painting, and some computers may travel into classrooms for parts of the school year. Networking computers--reconnecting a device to an existing network--is a time-consuming nightmare if you don't have the info right on the machines themselves.
If you don't set up good paper and spreadsheet lab management procedures, purchasing will soon be a nightmare, as almost no orders will be complete or exactly the total bottom line they quoted you, plus the idea of certified checks laying around in somebody's desk for weeks is fundamentally a bad idea. So is credit card purchase, for a school or business. So the rather bureaucratic business of setting up good procedures for purchasing--ordering, recording, checking it off, registering and marking it, certifying invoices as OK to pay, and writing down your operating budget as you place the orders (correcting it afterwards) is quite essential.
The basics are:
Of course all original disks of application and educational and game software should be secured too, but that's just school property security, this other is essential (and sometimes dangerous to the system) tools.
How much time does all this take? About 20-30 hours/week will be spent in the type of tasks described above during the first year the computer lab is functional--that is, you walk in the door, and computers are sitting on workstations, wiring is in, someone has networked them (sort of) and supposedly everything is all ready to go. I hope in fact you have a budget, because there won't be much software, and if someone other than the computer teacher did the ordering it wont be what you want for the students, and most of it won't be installed anyway; a bunch of packages in shrink wrap will be lurking somewhere. If that's your situation, don't expect to be presented with a neat log detailing system setup; you'll have to figure that out by experiment. The first time something goes wrong, it will be many hours before you can figure it out. In staffing the computer lab, school administrative people must take account of these time-and-task facts. If there is just one computer teacher responsible for all this, that person will either be putting in 60-70 hour weeks or will be available for teaching only half-time. Administrative tasks--paperwork, tinkering, repairs, purchasing--will never occupy less than 10 hours/week in the functioning all-school computer lab that is running smoothly.

How long does it take? If you are starting from scratch--scratch being even a few computers scattered about here and there--it takes one full calendar year--starting the previous school year and ending at the beginning of the next school year--to have a lab in place. Construction--wiring and cables in the floor, new circuits, phine installation-- that can be done only during the summer is nearly the last step. You shouldn't try to plan this as occurring during any mid-year school break. As well as floors torn up in the room that will be the lab, you will also have bulky workstations and charis arriving--20 to 30 of them. These are truck-shipped "KD" or "knocked down" in pieces. They come in bulky boxes, generate incredible amonts of packing trash, and have to be screwdriver-assembled. If you try to do this during the school year, halls and any open spaces such as gym or cafeteria are going to be filled with boxes and partly-assembled workstations and chairs. The computers and printers are bulky and packed with plastic too. Software seems to be typically shipped in big boxes filled with bulk packing materials. You will be knee-deep in plastic peanuts each time a medium-sized order arrives.The whole summer will be required for wiring, getting and assembling the furniture, putting the computers together, networking them, installing software--with all the checkoffs, complaints to vendors, and final paper OK's suggested above in the purchasing procedures. The last stage--the summer setup of the lab--is really a full-time job for 2 people, assisted by the building's maintenance staff who help unpack, assemble, carry, and carry out junk. To assemble an allegedly EZ-to-assemble workstation of the recommended dropped-keyboard-tray type takes a handy person about 45 minutes if there are no serious mismatches in pre-drilled holes. Usually there is. Assembly goes faster if 2 people can do it, one holding pieces together, the other putting in the screws. Chair assembly is also required, but usually goes faster, because seats and backs are usually wood, so screws can be forced through pre-drilled metal frames into mismatched holes in seats and backs, where in metal-to-metal mismatches, you have to use a metal drill to ream out matching holes. Return of such defective workstations or chairs--the defects are very common--is such a hassle that you should instead prepare to fix those mismatches. Assuming you have more than 2 nasties, complain bitterly to Customer Service, mention how many extra work-hours it was for maintenance to fix them, and try to negotiate a discount on the invoice.
Unpacking tip: Try to stash at least one complete set of boxes with internal foam packing materials for each type of machine. These will be required (forever) if you have to send them off for repairs. Unless there is a large lockable closet in your lab where you can hide this packing box stash forever, you won't find the box you need when you need it. Most warranties on hardware specify in the fine print that the original packing must be used on items returned for warranty service or other repairs. Of course you don't have to keep 20 of them! What you do have to (try to) keep is one of each kind. This is quite hard if they're somewhere that you can't keep an eye on them.
