piling up at the bottleneck.” Resource Utilization “The wait time is the ‘percentage of time busy’ divided by the ‘percentage of time idle.’ In other words, if a resource is fifty percent busy, then if a resource is ninety percent busy, the wait time is ‘ninety percent divided by ten percent’, or nine hours. In other words, our task would wait in queue nine times longer than if the resource were of the time, the tasks would spend in queue a total of nine hours time the seven steps…” Change Control  “We need to tighten up our change controls… what’s preventing us from getting there?”  “That

Template syntax A Tornado template is just HTML (or any other text-based format) with Python control sequences and expressions embedded within the markup: render("template.html", title="My title", items=items) Tornado templates support control statements and expressions. Control statements are surrounded by {% and %}, e.g. {% if len(items) > 2 %}. Expressions surrounded by {{ and }}, e.g. {{ items[0] }}. 6.1. User’s guide 27Tornado Documentation, Release 6.5.1 Control statements more or less map exactly to Python statements. We support if, for, while, and try, all

practices does not guarantee program success, as many variables that affect success lie outside the control of the government program manager and his team. In the government context, Agile represents a good This approach focuses on an integrated government-contractor release team, but could be more resource intensive. Figure 7 Multiple Release Team Example Management of Agile development requires dependencies on existing or planned capabilities must be understood. Some programs may use a Change Control Board for some of the larger backlog grooming decisions. In an Agile environment, users often

If you use multiple threads it is important to use IOLoop.add_callback to transfer control back to the main thread before finishing the request, or to limit your use of other threads to IOLoop

QA?Two types of resources ● Bottleneck - any resource whose capacity is equal to or less than the demand placed upon it ● Non-Bottleneck - any resource whose capacity is greater than the demand placed bottleneck produces in that time. And that makes an enormously expensive lunch break” Story - Quality control Jonah: “Make sure the bottleneck works only on good parts by weeding out the ones that are defective divide that time into four elements: ● Setup - the time the part spends waiting for a resource, while the resource is preparing itself to work on the part ● Process time - the amount of time the part

accelerate scientific research could result in cures for disease and solutions for climate change and resource shortages. As Demis Hassabis, CEO of Google DeepMind, has suggested: ‘First we solve AI, then use Assistant – 6/18-2/25, per Bank of America Erica acts as both a personal concierge and mission control for our clients. Our data science team has made more than 50,000 updates to Erica’s performance relative to prior analytical techniques with the remainder relative to a random baseline or holdout control.’ We indicate 2020 as the start year for JP Morgan’s AI Modernization (2020 Letter to Shareholders:

dominated the IT world because it appears to offer predictability, control, and efficiency, the key values of the contractor-control model. But it doesn’t. Requirements: Requirements are a way of controlling used to set boundaries for developers when they began a project. In other words, a vehicle for control. But standardization also imposes costs by:  limiting agility and adding bureaucratic waste: exceptions project sponsors (1) developing a formal proposal that incorporates estimated benefits, risks, and resource requirements and (2) submitting the proposal to decision makers who select preferred investments
