Hello, I’m Darlene Pike. I’m dedicated to agile ways of working. I love coaching teams, and (very) occasionally I write about it here. To know what’s on my mind today, connect with me at @darlenepike. Finger Focus allows you to create blur effects on your photos just by tracing your finger through the photo. Even if you roughly trace over the photo to apply the blur effect, the border of the effect will be automatically corrected, and the app will easily give a natural photo effect. The FINER method can be a useful tool for outlining research criteria used in the construction of a research question. Due to the flexibility of the criteria, this method may be used for a variety of research scenarios. The FINER method prompts researchers to determine whether one has the means and interest to conduct the study.
This calculator will find either the equation of the parabola from the given parameters or the axis of symmetry, eccentricity, latus rectum, length of the latus rectum, focus, vertex, directrix, focal parameter, x-intercepts, y-intercepts of the entered parabola.
To graph a parabola, visit the parabola grapher (choose the 'Implicit' option).

- In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`.
- In general, you can skip parentheses, but be very careful: e^3x is `e^3x`, and e^(3x) is `e^(3x)`.
- Also, be careful when you write fractions: 1/x^2 ln(x) is `1/x^2 ln(x)`, and 1/(x^2 ln(x)) is `1/(x^2 ln(x))`.
- If you skip parentheses or a multiplication sign, type at least a whitespace, i.e. write sin x (or even better sin(x)) instead of sinx.
- Sometimes I see expressions like tan^2xsec^3x: this will be parsed as `tan^(2*3)(x sec(x))`. To get `tan^2(x)sec^3(x)`, use parentheses: tan^2(x)sec^3(x).
- Similarly, tanxsec^3x will be parsed as `tan(xsec^3(x))`. To get `tan(x)sec^3(x)`, use parentheses: tan(x)sec^3(x).
- From the table below, you can notice that sech is not supported, but you can still enter it using the identity `sech(x)=1/cosh(x)`.
- If you get an error, double-check your expression, add parentheses and multiplication signs where needed, and consult the table below.
- All suggestions and improvements are welcome. Please leave them in comments.

Some Scrum Teams find it difficult to stick to the commitments they make. While it can be for many reasons, a common one is that a team is being interrupted with urgent tasks that take attention away from the work that they planned.
What are some of the tools we can use as Scrum Masters to confirm that interruptions are really a problem for our teams, and to help them adjust to a more predictable way of working? Here are three tools that I’ve used with some success:
1. Make the “interruption” work highly visible to the team, and also to those who are doing the interrupting.
Making things visible is usually a good idea in general. Going on the idea that interruptions potentially cause a slowdown or drag in the pace of work that was planned, making it easy to notice the interruptions can help people to notice the resulting drag. When everyone can see the drag, we can have more productive conversations, and consider course corrections that might help.
During a sprint, I might use different colored cards on the Scrum Board to make additional work or scope changes more prominent. At the end of a Sprint, I might show a report during Sprint Review, showing what the Scrum Team actually worked on that was different from what they originally committed to. Most tracking tools can generate reports when stories are added to sprints after Sprint Planning, for example.
It sounds easy, right? In fact, tracking interruption work can be very easy. The difficulty usually comes in with the discussions that need to happen. In order to get to a place where the team can work more productively, we need to attend to the needs of the people who are causing the interruptions.
One thing that can get in the way of the needed discussions is a team’s own awareness and fear that, by calling attention to the extra interruption work they are doing, they will solicit disapproval. People who feed the team extra work are often powerful and influential. It’s hard to say “no” to a favor from your boss. Being sensitive to this, as a Scrum Master, you might ask the team itself for ideas about what might help in their unique situation. You might work towards better connections and relationships between the team’s Product Owner and adjacent stakeholders. Through conversations, everyone may come to better understandings and agreements about how best to interact with the team, and get the urgent interruption work done without adversely affecting the planned work. This brings me to the second tool.
2. Coach the team in application of the Scrum Values (Commitment, Courage, Focus, Openness, Respect).
The Scrum Values are always a handy tool. A Scrum Master can help to build an environment of trust by teaching these values. Acronis true image 2020 mac download. That awareness of the values, and the trust that is built, goes a long way towards resolving problems related to work interruptions.

- Clearly, Commitment applies here. The Scrum Team has made a commitment at Sprint Planning, and the goals of the Scrum Team may be at risk whenever new work is inserted into the Sprint.
- With Courage, the Scrum Team members will be able to speak up and escalate when interruptions cause a loss of Focus on their goals. It may take some intervention on the part of the Scrum Master to ensure that the message that the team should not be interrupted gets to the people who need to hear it.
- The team should be able to display Openness with stakeholders and also with themselves about the challenges of the work. This may happen through ongoing transparent reporting. A conversation could be triggered at a retrospective. A Sprint Review may not be the place to go into a deep dive about why work was not completed, but it can be a place to bring to light some of the challenges that otherwise would be hidden. Once noted, other actions may be initiated.
- Respect (the idea that the team members are all capable and independent) is always essential. On a team that lacked maturity, I overhead one team member disparage their teammates for being “lazy” and not completing tasks soon enough. What was overlooked was that those team members had been asked to do side work for another initiative for their manager. In this case, respect (of the goals of the Scrum Team) was lacking from the organization, and also within the team.

3. Coach the team to understand its velocity and to make the most realistic commitments possible.

Finally, once the “interrupt” work is visible, and we have done all we can to apply the Scrum Values, we should turn our attention to the reality of how much work the team has proven it can complete in a sprint (the velocity).
Even if the interruptions are not formalized as user stories and brought into sprints, it may be possible to quantify and predict the rate of interruptions. Knowing this as a range will help the team to be more accurate when planning new sprints. If we know, for example, that we have a “drag” rate of about 30-40 hrs of team time per sprint, then we could reserve that time as a buffer during planning. By committing to fewer planned stories during a sprint, there will be a greater chance that the stories we do take on will be completed. We may even come to a place where we can set a service level agreement and communicate that out to other people and teams who make unpredictable requests of us. For example, we may be able to communicate out a lead time for new requests. It may be acceptable to the requestor and everyone may realize that what is being asked is not as urgent as originally thought.
