What do you like best? I like PDFFIller because it always works, unlike some other PDF tools I've purchased in the past. PDFFiller is my goto tool and will become my exclusive tool once my other package expires. What do you dislike? There's a little confusion when saving to my Google Drive. Now and then, the file can't be found there when on my phone. Recommendations to others considering the product: I've also used Ecopy for several years and just find PDFfiller to be more user friendly and stable. As I said, it's my goto PDF tool. What problems are you solving with the product? What benefits have you realized? I fill in forms, I create forms listing medical issues/histories, electronic signatures are always handy. I also convert to Office Documents if needed.

Easy to learn and easy to use.
What do you like best? Easy to learn and easy to use. I use it for filling in permit application forms from the county agencies we need to apply for permits from. They are extremely frustrating in redundancy, asking for the same information over and over. PDFFiller makes it easy to fill out these forms. What do you dislike? Some of the buttons seem a little clunky but they are easy to use. Recommendations to others considering the product: PDFFILLER is an inexpensive alternative to other vendors. What problems are you solving with the product? What benefits have you realized? Easy to fill PDF forms and easy to share them with other people.

I have tried many different programs.
What do you like best? I have tried many different programs. I find PDFfiller to be the easiest to use for anything re: PDFs and to get signatures on paperwork. What do you dislike? It is a little more expensive than some of the other programs. Recommendations to others considering the product: I highly recommend it for people who are not technical experts. What problems are you solving with the product? What benefits have you realized? Signing documents, converting WORD files, editing PDFs

Questions & answers

A software design document—sometimes called software design specification—is a detailed plan for developing a piece of software. An SDD should outline the finished software's functionality (specs) and your team's plans to build it (timeline, goals, etc.).
Usually, the design requirements (specifications) document includes the following things: Full project overview. Main needs and goals. Target audience. Functional requirements and desired set of features. Aesthetic aspects. Non-functional details. Recommendation and prohibitions. Questions.
The stages of software design process are: Stage 1: Understanding project requirements. Stage 2: Research and Analysis. Stage 3: Design. Stage 4: Prototyping. Stage 5: Evaluation.
What Should an SDD Include? Title. Title of the project. Authors and reviewers. These are the authors of the document. Introduction. General information about the project and its purpose. Roles and responsibilities. Overview. User interface. Functions. Scope.
The purpose of the Software Design Document is to provide a description of the design of a system fully enough to allow for software development to proceed with an understanding of what is to be built and how it is expected to built.
To start, the following is a list of sections that you should at least consider including in your next design doc: Title and People. Overview. Context. Goals and Non-Goals. Milestones. Existing Solution. Proposed Solution. Alternative Solutions.
