We need to first understand the history of websites and web design…The web used Mosaic to the browser and it was very simple in the beginning. It used HTML and used a text editor to build a website. Later, people who were even none-techie want to share “content” so the Contents Management System was created and it was known as CMS. It is a platform that has got structured modularly tools, allowing users to manage (add, edit, delete) the content of a website. Users can manage different types of formats and digital files (files, images, videos) without facing problems with CMS.CMS in DetailsContent Management Systems were developed to resolve this dilemma. A CMS helps you create and store content in a shared repository. It then manages the relationships between content items for you (e.g. keeping track of where they fit into the site hierarchy). Finally, it ensures that each content item is connected to the right style sheet when it comes to being published. Some CMSs also provide facilities to track the status of content items through editorial processes and workflows.CMS’s BenefitsThere are some important Content Management Systems and their typesA CMS can make it easier to create and publish content, to co-ordinate teams of authors and editors, to control branding, and to reuse content across multiple channels. There are numbers of benefits as below:Create and publish content in a standard format without needing to know HTML or other languagesCo-ordinate the work of teams of authors and editors (e.g. by ensuring that only one person is editing any individual content item at any one time)Control the branding and quality of the content (e.g. by ensuring that the correct style sheets are applied and that changes to the content are approved before they are published)Reuse the same content item in multiple different sites and formatsMain CMS’s OverviewA content management system, usually under specific requirements, are developed by specialist companies:1. WordPress, Blogger, TMZ: Used for personal websites and Blog: cost open Source and publication on 20032. Joomla, Drupal: GENERIC platforms3. Typo3: cost open source4. Vbulletin, phpBB, SMF, IPBoard: Forums used to discuss topics of interest.5. Magento, PrestaShop, ZenCart, DigiStore, OsCommerce: Used for electronic commerce (E-commerce Websites)6. Moodle, WebCT, ATutor: Used for educational purposes (E-learning)Important of CMS’s UsagesA CMS that can be as simple as including a module made by third parties, without incurring many changes in the web. The system can grow and adapt the future needs.Maintain a lot of pagesA website with many pages, CMS can provide distributions the work of creating, editing, and maintenance to permits access to different areas. With CMS, users can manage metadata of each document version, publication and expiration pages and broken links, among others.Reuse of Objects or ComponentsA CMS allows the recovery and reuse of pages, documents, and in general any published or stored object.Interactive pagesStatic pages are served to the users that are stored on the webserver. In contrast, dynamic pages do not exist on the server as received in browsers but are generated according to user requests. Thus, when such a search engine is used, the system generates a page with results that did not exist prior to the request. To achieve this interaction, the CMS connects to a database that makes a central repository of all web data.Changes of AppearanceIf there is a good separation between content and presentation, a change in the website may require the review of many pages for its implementation. CMS facilitates changes with the use, for example, the standard CSS (Cascading Style Sheets) so that the independence of presentation and content is achieved.ConsistencyConsistency on the web does not mean that all pages are equal, but there is a (visual) order instead of chaos. A user immediately notes when a page is not like the rest of the same web in appearance, the disposition of objects or changes in the navigation. These differences cause a feeling of disorder and suggest that the website is not designed by professionals. CMS can apply the same style on every page with CSS mentioned, and apply the same structure by patterns of pages.Access ControlControlling access to a website is not simply to allow entry to the website, it is also necessary to control the different permissions to each area of the website, applied either to groups or individuals.The pros and cons of using a CMSWhen building a website with CMS, without coding PHP, or editing HTML, and CSS, there are some pros and cons that are shown below.Pros of using a CMSMany CMS options to choose from, including the most popular choices by web design and online marketing agencies are WordPress, Drupal, and Joomla.Faster development time, as it allows for quicker website design, as well as solutions to many of the development problems that can come up.Cheaper overall cost.Reduced web administration and web development expenses.No need to learn or write code.Choose from a wide variety of templates.Streamlines the process of multiple content contributors.Simple interfaces and easy to use.The straightforward process of creating and publishing content.A CMS has many pre-developed features, appliances, widgets, and plugins, so tailored development costs can be kept down.Customization is still possible.A great start-up option to test an idea with a market.The intermediate solution while a highly customized non-CMS site is being developed.CMS developers can assist with the initial design and then hand it over to the website owner with no further involvement necessary.A CMS is SEO-friendly — they have evolved to include custom page titles and metadata, and adjustable URLs; and helper plugins are available as well (like automated XML site map submits).Cons of using a CMSReduced flexibility.The more specific the features of a website need to be, the less likely a CMS will work for it.Although robust and always improving, CMS website-building tools are still somewhat limited. Full customization is not always possible.Some training is required to use a CMS effectively, as well as keep it updated.It can break if configured incorrectly by an admin.It requires updates – this takes time and needs dedicated people to ensure it is kept updated.There are some malevolent hackers out there who can figure out how to break into these platforms; so, security will require extra precautions.It may make the website an easier target for spammers and hackers if not updated.It uses more server resources than static pages.Not everyone wants to see their data in a database. Outside the CMS administration, it can be a chore to edit database content; however, this is rarely a legitimate issue, as databases are scalable, generally faster, and space-efficient.Final Takeaway on CMS (Content Management Systems)Using a content management system will save significant costs to build the web’s contents, even in just a short time. A CMS can provide much-needed functionality to help you leverage your information assets and get your tech writers collaborating on a fundamental level.Content management systems can contribute to the flexible management of online and offline platforms such as websites. Here, users can edit content such as texts, images, or videos and publish them. Many systems are not only open source, simplifying content publishing; they come with a large and helpful community.

This is a very good question to ask since many people go into hiring freelancers without understanding the intricate details that can make or break your project and/or budget. The advice provided here applies to people who do not have a technical background and also people with a technical background who are new to hiring freelancers and outsourcing development.The first thing you want to do before you hire a freelancer is to see if there are ready made templates or full solutions that can satisfy a majority of your requirements. This will not only save you money but will also get you thinking as to what you really need in your app from a functional user perspective. Templates for iOS can be found on sites like CodeCanyon, an Envato marketplace (I am not affiliated with them). You can also find hybrid templates that work on iOS, Android and other platforms which will require a different set of skills but will allow you to deploy to many more app stores. Templates can be full apps that need customization on the user interface, content and backend development or they can just be themes/mockups/designs for the front-end like CSS/HTML/Javascript or Photoshop/Illustrator design files styling. The great thing about doing this first is you will be better informed and equipped to negotiate a contract and design requirements. Spend at least 16 hours doing this and you will save hundreds of hours in development and design time.Whether you find a full/partial or no design template at all you will still need someone to customize it and integrate it to a backend if you intend to do any kind of networking and server based database work. The assumption you made is that you only need one software engineer. This will be the first thing you want to avoid. Do not hire just one software engineer that says they can do everything. You will eventually need to hire someone else when they are asked to do something they can't handle within your budget and timeline. It is also better to use the terms front-end, user interface, back-end, integration, developer, programmer, designer, architect than software engineer since software engineer is a vague term and for some people it is a technically incorrect use of the term engineer. So what do you need to do? Since this may be your first iOS app I suggest you work with an agency that has a team of developers and can give you a fixed price on the full project from design, development, testing, deployment and maintenance. This will reduce your costs (not guaranteed) since you can negotiate a better fixed price and also increase (not guaranteed) your chances of the project coming in on time and within budget.Before you create a job post you will want to create a detailed requirements document that can be a simple spreadsheet or text document listing everything you need the app to do from a user perspective. Also create a flowchart to help visualize how your users will flow through the app. The more detail the better. This will serve as your user interface, use case and functional requirements document all in one. There are many online resources that teach you how to do these requirements docs so I won't detail them here. Most well managed projects will have separate documents for each but you will be able to accomplish the same with one or two very well thought out requirements doc. You will not be able to create the technical design unless you have done many of these in the past. This is where the design/template research will come in handy as you will be able to include readymade screenshots of your concept. Without existing readymade designs you will need to at least create wireframe designs which show each and every screen/view your app will have. Everything from login/signup forms, to settings, lists, data entry forms, popups etc... Do not leave any screen/view out. You can draw them by hand or use any drawing/design tool you want. The key is to include everything the user will have to interact with since this will determine how you build the client front-end (what the user sees on their mobile device) and back-end (server and database code that does work). If the team you hire is good they will let you know up-front in their proposal if there are any issues. Spend at least 80 hours on developing your requirements and you will save countless hours in change requests, meetings and overall distress. Get feedback from potential users and modify accordingly until you feel your users are getting what they need. This is very important since they will tell you what they need not what you think they need. The design requirements should be at least half of the effort and be completed before you create a job post.Once you have the design doc(s) with screenshots, user functionality and screen flow requirements you can create the job post. Fill out the form and include a summary description of your app. You don't have to give any details of what the app will be used for just what it will do. Upload your requirements doc(s) and reference them in your summary description. Select that you are only looking for agencies at this time unless you want to hire 3-5 different freelancers and manage them (don't do this). At the end you will be able to ask questions you want answered in your proposal. Some of the questions I like to ask are:Show 1-2 mobile applications (in your case iOS) that are currently in the app store. -Eliminate any proposal that did not provide this.Who will be part of the project team? -Eliminate any proposal that does not include a PM, Business Analyst, Tech Lead-Developer, Mobile iOS Developer, Designer (Optional if you have designs ready made), Back-End Developer, Testers. Some roles can be done by the same person such as PM/BA. Front/Back End developer can sometimes be the same person if the project is not too complicated (judgement call). Developers should not be the testers. You will negotiate with the account manager who will be there if you have any complaints/issues with the quality of work or performance.What is the expected duration (how long from start to finish) of the project?What is the expected effort in hours of the project?What is the guarantee period after delivery of the app?Do you provide app store submission services? -Optional unless you need someone to do the app store deployments with your app store account.Describe your development process and what will be expected of the client.What are some potential issues with the job requirements/description?What technologies will you use for the front and back end? For front end iOS they will say Swift, Ojective-C or Cordova/PhoneGap/Ionic. For full native use swift as that is the language Apple will be solely supporting in the future. Use Cordova for hybrid apps. Objective-C as a last resort. Back-end database and server language can be anything although you will probably want to go with what makes sense for your business/app. You can use something like Parse which provides a full back-end as a platform or build your own on something like Node/MongoDB and host on AWS/Azure/Bluemix or any cloud provider.What online project tracking tool do you use?What online code repository do you use for version management and delivery?Ask anything else you want related to your specific app.Stating your fixed price budget is a bit more involved. If you price it too low you may not get as many quality proposals. Too high and proposals will always be close to your budget without taking into account the true cost. This takes time and experience to get right but here are some numbers based on the costs I have seen to get you started:$1k and below will get you the simplest of apps with little to no back-end integration. Not recommended for full customer facing app. Will be good for proof of concept apps that are not for production use. I will often do these small projects to test out an idea with potential customers. It will have enough functionality to give users something tangible to provide feedback on. This is also a good way to vet a team without risking too much budget.$1k-5k will get you most simple (1-2 database sets without advanced user management) data driven apps (not high end games or large database/back-end integrations) for one native platform or hybrid app.$5k-10k will allow you much greater flexibility in terms of what you can build and allow you to target iOS and Android native apps.$10k-20k will get you most anything data driven.$20k+ I would not put a budget of this size. Best approach is to break down your project into separate jobs with short 3 or less months duration.Leave your job open for at least one week but no more than two weeks. Once you start getting proposals eliminate all proposals that do not meet your criteria for budget, timeline, process, team etc... You will get a sense of the of the right price after getting about 12 proposals. Get rid of the top and lowest bids right off. Ask additional questions based on the answers provided from your initial questions. Narrow down your list to a 3-4 finalists. Schedule a Skype or phone interview for an hour and get to know how they speak, communicate and overall how you get along. If they say yes to everything you ask eliminate them. For people without a technical background I recommend you hire another freelancer with a lot of experience on an hourly basis ($50-80 per hour, 5 star reviews, similar projects to your own) to evaluate the agency during your interview. This freelancer can be your on-demand consultant when you need objective technical advice. After many projects you may have more than one go-to people who you trust.Once you select a proposal it's time to negotiate terms. Send them your NDA doc to sign as part of the agreement. Clearly state how long the vendor will provide fixes for any issues found after delivery of your app. Clearly state that your milestones will be considered delivered once the code has been checked into via your Github or similar code repository. You can have someone review the code if needed at this point before payment. Collect any tax documents/info like an I-9 if needed. I don't think this will ever be used to sue someone but it let's them know you don't want anything shared outside their company for any reason. Price can still be negotiated but typically I don't do that if the price is not an issue and will only save you a couple hundred dollars as it just wastes time and provides a tiny bit of incentive to the vendor to under deliver/perform. You can set bonus (5-10%) contingencies for early or on time delivery of your app. This provides a good positive motivation and return on your investment if your timeline is strict. Break your milestones into 2 week deliverables. Only fund the first two milestones. Do not pay anything upfront although some will ask for an initial fee to get started. Do not release payment until the milestone has been met. Use your requirements doc to break up the work and make each requirement part of one of the milestones. If the requirements is not met then do not move forward. Have them agree to the milestones or have them provide their suggested milestones and hold them to it. Stop working with the agency if they do not deliver the first 2 milestones as required and on time.While working with team make sure they are always available on Skype or on the phone for whatever reason. Use an online project management tool to keep track of requirements and dates. I use Asana to keep things simple and allow the vendor to create and manage tasks as well. There are other tools with more technical functions but those should be used and managed by the vendor and not the client. Your concern is with the requirements and timeline not bug tracking. Meet at least 2 times a week with the PM/BA to go over any issues and review changes to the timeline. Nothing should be a surprise. Keep archives of all chats and emails not done through the Upwork system. End the project if they consistently take more than a day to get back to you. Use the first two weeks as a probationary period if you have never worked with them before. At the end of two weeks decide if you want to keep working with them or let them go. If you have any doubts let them know your concerns within a few hours of experiencing your issue with written proof. Give them time correct the issue or let them go if they do not improve. Make sure you have a good reason though. If you start having issues with more than a couple of teams it may be that you are the problem and not the team.At the end of your project when everything has been delivered as required determine if there are any changes that came up during the project that you need implemented. You can address these changes during the project timeline but keep into account that your initial timeline will be affected. If you start doing more than a few change requests during your project it is best to stop the project and start it over again once you figure out your requirements again. During the guarantee period (should be at least 30-90 days) make sure you report issues immediately and keep track of them using your project management tool. At this point you have already provided all payments so fixes will be dependent on the vendor to abiding by their guarantee.Treat your vendor team members well but if you are having to many unresolved issues early on it is best to cut them loose within a couple of weeks and find another team. There should not be any need to threaten or micro-manage any of your teams if they are professional and listen to your concerns. Let them know when they are doing something well. If you have to cancel a project due to an issue that is not due to the vendor you should provide an appropriate review and let them know as soon as you can when you will end the project. Provide a bonus at the end of the project if they exceed your expectations. You get reviewed as well.There is a lot more not covered but this should provide a good starting point for your endeavors. Feel free to ask any other questions.
