Compressing the schedule

If you have three weeks or less before the exam, you have your work cut out for you. Carve half an hour out of every day for study. This schedule assumes that you have the whole three weeks to prepare in if you have less time, you will have to compress the schedule accordingly. Study only the chapters that are relevant to the type of exam you will be taking.

Trying to compress the schedule by more than 10% could be very dangerous. Studies on the subject suggest that while a 10% reduction would impact the project cost by 3-5%, a 20% reduction could be unaffordable for most projects. 

Incorporate the costs of compressing the schedule into the estimate and adjust the contingency to reflect the related risks. 

In most situations, the backup software that comes with most operating systems is adequate. However, you can buy backup software that has more features than the included software. Some of those features include data compression, backup scheduling, and greater hardware device support. 

These are the phases that a capital project passes through from inception to dedication. Overlapping of the phases and compression of schedule is commonly achieved through an approach called fast tracking. It... 

History has a tendency to repeat itself, which in this case meant that due to a compressed delivery schedule, there was only very limited time available to gain a good understanding of the new route and, furthermore, to improve on some of the underperforming steps. A quick scale-up to satisfy the needs for API, to initiate clinical phase I studies, resulted in a yield of only 0.3%, which did not compare favorably to the laboratory yield of 5%. This batch produced 2 kg of robaizotan of outstanding quality with an enantiomeric purity >99% ee. The major flaws in the chemistry (expressed as poor yields) occurred exactly where they had been projected as mentioned previously, and it was obvious from working on pilot scale that virtually all steps were hampered by low volume efficiency (amount of material produced per unit reactor volume) and complicated workup procedures. 

Although many commercial technologies have been developed using this strategy, resource and time constraints may limit the scope of the development efforts. Often a compressed development schedule will require... 

The critical path is identified for two reasons. First, if unexpected issues or changes occur to a given task after the project begins, the impact, if any, on the overall project schedule can be determined quickly. Second, knowing the critical path enables the project manager and team to consider quickly where the schedule can be compressed to accommodate project imperatives and unexpected changes. 

Based on our experience as we have been associated with the design and construction of many slipformed concrete headframes in the past, including designing four within a three year period, we expected this was another area where schedule could be compressed. The remaining portion of concrete above the foundation beams was 53 m high, and was slipform constructed in only nine days (refer to Figure 6). 

There may be a desire to use up more time in commercial negotiation in order to get better deals from suppliers and contractors, thereby effectively compressing the engineering schedule to maintain the overall project schedule. 

One example of the compression-molding process is outlined in Table 12.7 [28]. Polyamide-imide powder particles with a maximum particle size of 150 jm and a median particle size in the range of 10 to 50 pm are preheated in an oven for 1 to 24 h at 260 to 316°C. The purpose is to increase molecular weight and complete the imidization processes, both of which create water and can lead to voids in the compression-molded article. The compression-molding schedule depends on the size and geometry of the mold. A pressure-molding schedule for a 14.0 cm X 1.6 cm disk mold is shown in Table 12.8, where the mold temperature is set in the range of 315 to 329°C. 

The effects of the compressed schedule were evident in other areas. Five of the seven flight controllers who were scheduled to work the next mission lacked certification, but as a result of the schedule pressure, managers either were willing to delay recertification or were too busy to notice that deadlines for recertification had passed ... 

Example 8 Compressible Flow with Friction Losses Calculate the discharge rate of air to the atmosphere from a reservoir at 10 Pa gauge and 20 G through 10 m of straight 2-in Schedule 40 steel pipe (inside diameter = 0.0525 m), and 3 standard radius, flanged 90 elhows. Assume 0.5 velocity heads lost for the elhows. 

The gut bubbles in adult brine shrimp did appear, however, to form from gas nuclei (ref. 419) these presumably were incidentally ingested by the animals during filter feeding. Thus a slow compression schedule increased the number of bubbles by apparently preserving nuclei during compression to the equilibration pressure. At each pressure level, gas could diffuse into the gas nuclei, tending to stabilize them against collapse when further compressed. Prepressurization had the opposite effect, as it would tend to reduce the number of bubbles as a result of presumed dissolution of many gas nuclei (ref. 419 see also Sections 1.3.1 and 1.4.3). 

If the cost of execution were the only consideration, the optimum schedule would also be the minimum cost case, and any schedule compression would automatically result in a cost increase. When that is not the case, the obvious explanation is that the initial schedule was not the optimum one. 

Evaluate the various schedule/cost trade-offs to develop a reasonable risk compressed schedule and estimate the associated cost penalty. 

HPI AF is a 55-year-old woman who is scheduled to undergo left hip replacement surgery. While in the operating room and postanesthesia care unit (PACU), she has on thromboembolic deterrent (TED) stockings and sequential compression devices (SCDs). On postoperative day 1, the SCDs are discontinued, and she is started on enoxaparin for deep vein thrombosis (DVT) prophylaxis. On postoperative day 7, as AF is getting ready for discharge, she becomes acutely short of breath and develops a painful and swollen left leg.
